Windows 7 - how to remove "Install updates and shutdown" option from the power button

2011-09-08T14:14:00.001+03:00

How many times were you forced to quickly shutdown the computer but couldn't because Windows needed to install updates first and then shutdown?
Sometimes I just don't have time to wait for Windows 7 to install updates and then shutdown. This happens at my workplace where due to the fact that electricity stops after work hours are done I must turn off the computer before power outage. So, to get rid of this awful feature (for me) I chose a simple solution. This works by modifying an option from Windows Update Policy Settings. Here are the steps to follow:

- Open Start menu, enter gpedit.msc in the search box and launch gpedit
- go to User configuration > Administrative templates > Windows components > Windows update
- double click on Do not adjust default option to 'Install Updates and then Shut Down' in Shut Down Windows dialog box to edit option.
-after the edit window opens, click on Enable and then Apply. Close everything and you're done!

Opensuse 11.4 - Install flash player 64bit on Firefox 4 x86_64

2011-03-28T20:43:00.007+03:00

Since I started using Firefox 4 beta x86_64 on OpenSuSE 11.3 I noticed that some flash players from different websites were not working properly. On some flash players or flash animations I had white rectangles appearing over images. I hoped that this would be fixed when Firefox 4 would be released or after I upgraded to OpenSuSE 11.4, but the problem persisted.
One solution for this flash player problem would be to uninstall the 64 bit version of Firefox and install the 32 bit version, but this would result in a decrease of speed for Firefox.
The second option is to uninstall the 32 bit version of the flash player which comes with OpenSuSE 11.4 and install a 64 bit version of Adobe Flash which is available from Adobe Labs. They developed Adobe Flash Player "Square" which is a preview release that enables native 64-bit support on Linux, Mac OS, and Windows operating systems.
Before installing flash player "square" you must uninstall the previous version of flash player. To do this, open kick-off menu, go to Computer and click on Install/Remove Software. After the software manager opens, search for "flash" and select to uninstall flash-player and pullin-flash-player.
Now go to http://labs.adobe.com/downloads/flashplayer10_square.html and click on "Download plug-in for 64-bit Linux (TAR.GZ, 4.1 MB)".
Next step is to install the flash player "square":

- go to the location you saved flashplayer10_2_p3_64bit_linux_111710.tar.gz and extract the .tar.gz archive
- copy libflashplayer.so to /usr/lib64/browser-plugins (note that you must do this as root):

sudo cp libflashplayer.so /usr/lib64/browser-plugins

Restart Firefox and open a web page that contains flash animations or a flash player that you know previously didn't work.

Important: Please note that if you install the Flash Player "Square" preview, you will need to keep this version up to date by manually installing updates from the Flash Player "Square" download page on Adobe Labs. You will not receive automatic update notifications for future final releases of Flash Player, and you will need to manually uninstall Flash Player "Square" before installing a final shipping version of Flash Player.

Opensuse 11.3 - instalare TV-Maxe, program pentru linux cu posturi tv romanesti online

2011-02-17T15:35:00.004+02:00

Intr-un articol anterior prezentam aparitia TV-Maxe, un program romanesc, bazat pe pluginul sopcast, care ofera posibilitatea vizionarii online de posturi tv romanesti in Linux. Dupa cum e scris si in acel articol, TV-Maxe este impachetat de catre autorul sau in pachet .deb pentru Ubuntu si .tar.gz. In acest ghid va voi arata cum sa instalati TV-Maxe in Opensuse 11.3.
Dupa cum stiti Opensuse foloseste pachete .rpm pentru instalarea de softuri, de aceea va trebui sa convertim pachetul tvmaxe.deb in pachet .rpm pentru a-l putea instala.

Intai de toate navigati pe aceasta pagina pentru a descarca ultima versiune a TV-Maxe.

De asemenea, pentru a rula corect programul trebuie instalate urmatoarele dependinte: libstdc++5 si sp-sc-auth (executabil sopcast in versiune linie de comanda). Pentru a le descarca faceti click aici (mergeti la sectiunea Sopcast 3.2.6 for Linux) sau faceti click pe urmatoarele linkuri: http://download.easetuner.com/download/sp-auth.tgz si http://www.sopcast.com/download/libstdcpp5.tgz .

Deschideti acum un manager de fisiere (Dolphin daca folositi KDE sau Nautilus pentru Gnome) si navigati spre cele doua fisiere descarcate (de obicei ele sunt salvate de Firefox in folderul /home/nume_utilizator/Downloads). Faceti click dreapta pe fiecare si alegeti Extract here... Vor rezulta 2 foldere, unul intitulat sp-auth care contine executabilul sp-sc-auth, iar celalalt va fi usr si va contine un subfolder numit lib, in care veti regasi fisierele libstdc++.so.5, de tip shortcut si libstdc++.so.5.0.1.

Deschideti un terminal linux si logati-va ca root (tastati su si introduceti parola de administrator).

Navigati catre folderul in care s-au descarcat cele doua dependinte:

cd /home/nume_utilizator/Downloads

Inlocuiti nume_utilizator cu numele dumneavoastra sau cu numele ales la instalarea sistemului de operare.

Tastati urmatoarele comenzi pentru a instala dependintele:

cd sp-auth
cp sp-sc-auth /usr/bin/
cd usr/lib
cp libstdc++.so.5 /usr/lib
cp libstdc++.so.5.0.1 /usr/lib

Pentru a transforma pachetul tvmaxe.deb in pachet .rpm vom folosi programul alien care ar trebui sa fie disponibil deja in repertoriile software ale Opensuse 11.3. Pentru a instala alien tastati urmatoarea comanda:

zypper in alien

Dupa instalarea alien, putem trece la convertirea pachetului .deb al TV-Maxe in pachet .rpm, dar inainte de aceasta ne intoarcem in folderul Downloads unde este descarcat pachetul tvmaxe.deb:

cd /home/nume_utilizator/Downloads

alien -r tvmaxe.deb

Aceasta comanda va crea un pachet numit tv-maxe-0.04.1-2.noarch.rpm

In acest moment avem instalate dependintele pentru TV-Maxe si avem disponibil un pachet .rpm pentru instalarea TV-Maxe in Opensuse 11.3. Pentru a instala si TV-Maxe tastati urmatoarea comanda:

zypper in tv-maxe-0.04.1-2.noarch.rpm

Apasati enter in momentul in care veti fi intrebat daca doriti instalarea programului tvmaxe si asteptati terminarea instalarii.

Acum puteti lansa aplicatia TV-Maxe din meniul Kickoff la sectiunea Multimedia>More Programs>TV-MAXE

Windows 7 - How to share a folder

2011-02-01T00:17:00.001+02:00

In the previous article we learned how to enable file sharing in Windows 7. Now you will see how to share a folder in Windows 7.
There are more than one way to share a folder and in this tutorial I'll show the one I consider the fastest and simplest.
Navigate to the folder you wish to share and right-click it and choose Properties. After the properties window appears, go to the Share tab and click on Advanced Sharing...:

In the Advanced Sharing window click the Share this folder check box, enter a name for your share and
then click on Permissions to set the folder's permissions:

In the Permissions window you can set the network users rights on your shared folder. You can give full control over folder meaning read/write access or you can make it read only. To give full access to your network folder click the Full control check box. To make it read only make sure only the Read check box is checked:

Now click OK to close the Permissions window, then click Apply and then OK to close the Advance Sharing window and your folder will appear in your network.

Windows 7 - How to enable files and folders sharing

2011-01-31T00:29:00.004+02:00

In this tutorial I would like to help Windows 7 users who migrated to 7 straight from Windows XP, how to join a network and share files and folders on the network.

First of all you need a Windows 7 computer connected to a local area network. Network computers must be on the same workgroup so you can easily share files and folders between them.
To join the workgroup in your local network:

Open the Start menu and then right click Computer and choose Properties:

In the Properties window navigate to Computer name, domain and workgroup settings and click Change Settings:

A new window will appear. Here you can enter a brief descriprion of your computer (optionally). To join a workgroup click on Change button:

In the new window enter you computer's name and the workgroup's name and click Ok.

A welcome to the workgroup message will appear and click Ok. Then a warning message will pop up and click Ok to close it. Now click Close on the System Properties window and restart your computer.

Now your computer is on a Workgroup in your local area network but due to Windows 7 default network settings your computer is not yet ready to share files and folders. To enable file sharing you must:

Open Control Panel from the Start button and then go to Network and Sharing Center:

In the Network and Sharing Center window click on Change Advanced Sharing Settings from the left panel:

To enable file sharing and make you computer discoverable on the network make sure you check the settings like in the picture below:

Restart computer for all the changes to take effect.

Windows XP - How to add your computer to a workgroup

2011-01-27T13:35:00.002+02:00

If your computer is already part of a network, you can join a certain workgroup so you can see all the computers on the network. To join a workgroup follow some simple steps:

Windows cannot start because the following file is missing or corrupt: vgaoem.fon (EN)

2011-01-24T13:36:00.001+02:00

Few days ago my Windows XP Professional failed to start due to a power blackout and showed the following error:

Windows failed to start because the following file is missing or corrupt:
C:\WINDOWS\SYSTEM\vgaoem.fon

If for some reason this happens to you too, don't panic, the solution is very simple. Just make sure you have a Windows XP installation cd and follow these simple steps:

Setup your computer to boot from cd (do this from BIOS or press F12 or F11 to change the boot sequence; might be a good idea to check your motherboard manual first to see how to change the boot order). Insert your Windows XP installation cd and restart computer.

When the "Press any key to boot from cd..." appears, press any key to start computer from installation cd.

After the Welcome screen appears, press R to start Recovery console.

Choose the operating system and press enter. Type in the administrator password and hit enter or just hit enter if you don't have a password.

Type map and hit enter to see which letter is assigned to the cdrom device containing the installation CD.
Type the following command to copy and expand vgaoem.fon file (replace E : with the corresponding letter of your cd-rom drive. Do the same with C, replacing it with the corresponding letter of the partition where Windows is installed), then press enter):

expand E:\i386\vgaoem.fo_ C:\windows\system

Notice the underscore after "o" in "vgaoem.fo_".

A message confirming the operation will be displayed.

Type exit to reboot computer and remove the Windows installation cd. Now your Windows Xp should be fixed and start normally.

See here an official Micorosft guide for this: http://support.microsoft.com/?kbid=315338

Windows cannot start because the following file is missing or corrupt: vgaoem.fon (RO)

2011-01-24T12:03:00.004+02:00

Mesajul de eroare ce face titlul acestui articol, s-a intamplat sa imi apara dupa o pana de curent cand aveam calculatorul pornit. In cazul de fata fisierul cu erori este vgaoem.fon, insa aceasta eroare poate aparea si in cazul altor fisiere, cum de altfel mi s-a si intamplat.
Nu va speriati atunci cand observati ca Windows XP nu mai porneste dupa o pana de curent sau alte probleme cu tensiunea din prize (fluctuatii de tensiune). De obicei solutia este simpla, ca si in cazul acesta.
Pentru a rezolva problema asigurati-va ca aveti un CD de instalare de Windows XP si setati BIOS-ul sa booteze de pe CD (intrati in BIOS si modificati secventa de boot sau la pornirea calculatorului apasati F12 sau F11 in functie de placa de baza pe care o aveti).

Asadar, pasii sunt urmatorii:
Introduceti CD-ul in unitate si reporniti calculatorul, selectand apoi ca mediu de boot CD-ul (vezi mai sus), apoi la aparitia mesajului "Press any key to boot from CD", apasati orice tasta pentru a boota de pe CD.

Dupa ce apare interfata de instalare a Windows si meniul cu optiuni apasati "R" pentru a intra in Recovery console.

Dupa ce s-a deschis interfata MS-DOS a consolei, selectati sistemul de operare si apoi introduceti parola de administrator (daca exista, daca nu, apasati enter).

Tastati map si apasati Enter pentru a putea vedea ce litera corespunde unitatii optice (ex. E:\Device\CDrom0).

Tastati urmatoarea comanda (inlocuiti CD_ROM drive cu litera corespunzatoare unitatii optice care contine cd-ul de instalare, iar drive reprezinta litera corespunzatoare partitiei pe care este instalat sistemul de operare, de obicei C) pentru a copia fisierul vgaoem.fon de pe cd-ul de instalare in directorul Windows:

expand CD-ROM drive:\i386\vgaoem.fo_ drive:\windows\system

Atentie: observati in comanda de mai sus prezenta caracterului underscore sau "liniuta jos" dupa litera "o" in "vgaoem.fo_"

Va aparea un mesaj de confirmare a operatiunii, dupa care tastati exit si apasati enter pentru a reporni calculatorul. Scoateti cd-ul de instalare al Windows si porniti normal calculatorul (daca e nevoie setati ca prim mediu de boot hard diskul). In acest moment, Windows XP ar trebui sa porneasca normal.

TV-Maxe - TV online pentru Linux cu canale romanesti

2011-01-18T21:47:00.004+02:00

De mult timp, mai exact inca de cand am inceput sa folosesc Linux, am cautat o solutie simpla si usoara pentru vizualizarea pe Linux a posturilor tv romanesti care ofera si un stream live pe internet. Pana acum putin timp nu am gasit nimic, insa recent am descoperit TV Maxe.
TV Maxe este un program scris in limbaj python de catre un impatimit al Linuxului din Romania, care a incercat sa rezolve si, intre noi fie vorba a reusit cu succes, realizarea unui programel care, folosind ca player video mplayer si/sau vlc player, cat si pluginul pentru Linux al Sopcast, permite vizualizarea de posturi tv romanesti online.
Programul ofera un playlist predefinit cu posturi tv romanesti, iar cu un simplu click dreapta pe unul dintre posturi puteti vizualiza grila de programe a postului respectiv. Calitatea streamurilor variaza, insa majoritatea pot fi vizionate la o calitate inalta a imaginii. De asemenea, cum tot mai des televiziunile emit in raport 16:9, puteti selecta din program modul de afisare 4:3 sau 16:9. TV Maxe poate fi folosit si cu o telecomanda compatibila cu Linux, pe care o puteti configura din program.
Pentru utilizatorii de Linux Mint sau Ubuntu, TV Maxe se poate instala usor folosind pachetul .deb, care contine tot ce este necesar, disponibil aici.
Pentru instalarea TV-Maxe in OpenSUSE 11.3 aveti pe aceasta pagina un ghid util.

Opensuse 11.3 - configure local network

2010-09-30T12:14:00.004+03:00

If you use Linux then you well know that only few people use this operating system platform. For example, in my case, in the local network I use at work, I am the only user of Linux. So I have to join my computer to a network in which all computers run Windows. This is not a difficult thing to do because Opensuse 11.3 makes it very easy.
Opensuse 11.3 comes with the software needed already included so all you have to do is just configure it according to your local settings. Even so, better ensure you have Samba server installed. There are a few steps for joining the local network and I will show them to you in this tutorial.
First of all open Yast and open Network Settings. In the Global Options tab you usually don't have to modify anything and it should look like this:

Next select the Hostname/DNS tab. Here type in your hostname and your workgroup name and then click OK:

Now we will configure Samba Server. For this open Yast again if you closed it before and select Samba Server from the Network Services category.

The Samba installation has 2 steps. In the first step you have to type in your workgroup name, then click Next:

For the second step check the type of domain controller and then click Next. This will open the Samba Server configuration window:

In the Start-Up tab check During Boot in the Service Start field and Open Port in Firewall in the Firewall field:

Now select the Shares tab. You will see here a list of Available Shares where you can toggle their status according to your needs. In my case I disabled them all because I will add my custom shares later. Also make sure to check Allow Users to Share Directories and Allow guest access:

Select the Identity tab and choose your NetBIOS hostname and leave everything else as is. I use the same as the hostname I entered earlier when configuring network settings. Now click OK. A waning message will pop-up and click OK, then Samba will ask you for a password for the Samba Server. You can enter one or leave empty by clicking OK. I leave it empty because I want anyone in my network to access my shares:

We are only few steps away from finishing configuring Local Network on our Opensuse 11.3 system. Now we have to configure Firewall to allow some services needed by Samba to access local network, so launch Firewall from Yast from the Security and Users category.
After firewall opens, select Allowed Services from the list in the left and add NetBIOS server, Samba Client and Samba Server to the list of allowed services, then click Next and then Finish:

All the configurations are done. Now we need to reboot or restart some services so we can use the local network. The simplest way is to reboot, but if you don't want to, you can restart the network services by opening a terminal, logging in as root and typing the following commands:
- rcnmb restart
- rcsmb restart
- rcSuSEfirewall2 restart

Wait a minute or two for Samba to read local network and then you can start browsing your local network.

Opensuse 11.3 - Instalare driver Nvidia (II)

2010-09-17T11:30:00.003+03:00

Revin cu acest subiect datorita faptului ca de la lansarea OpenSuSE 11.3 s-au mai asezat lucrurile in ceea ce priveste repertoriile de software pentru SuSE 11.3 astfel incat nu mai este la fel de dificil de instalat driverul grafic Nvidia. Modalitatea aceasta de instalare a driverului pentru placi grafice Nvidia va inlocui automat driverul generic Nouveau cu care vine implicit Opensuse 11.3.
Pasii de urmat sunt:
- deschideti Yast, alelegeti sectiunea Software si lansati Software Repositories

- in fereastra care se deschide faceti click pe Add, iar in fereastra urmatoare selectati Community Repositories, apoi click pe Next

- se va deschide o fereastra ce contine o lista cu repertorii in care bifati repertoriul Nvidia, apoi faceti click pe OK. Se va actualiza repertoriul Nvidia, timp in care e posibil sa apara cateva ferestre de dialog pentru importarea unor chei pentru software in care faceti click pe Import.

- la sfarsit faceti click pe OK.
- acum puteti deschide Software Management din Yast unde cautati software-ul Nvidia. In cazul meu am instalat nvidia-gfxG02-kmp-desktop si x11-video-nvidiaG02, aceasta pentru ca placa mea video face parte din seria Geforce 6XXX sau mai noi. In functie de tipul placii dumneavoastra instalati driverul potrivit (pentru a afla care este cel potrivit verificati descrierile pachetelor). Dupa ce ati stabilit driverul, selectati-l pentru instalare, apoi faceti click pe Apply. Instalarea driverului Nvidia va dezactiva automat driverul Nouveau.
- dupa ce se termina instalarea e indicat sa reporniti calculatorul.

O alta metoda de a instala driverul potrivit pentru placa dumneavoastra video este ca dupa ce ati selectat repertoriul Nvidia, sa lansati Online Update din Yast. Se va deschide o lista cu toate update-urile disponibile pentru sistemul dumneavoastra printre care ar trebui sa apara si driverul Nvidia. Apasati Apply, asteptati sa se termine instalarea, dupa care reporniti calculatorul.

OpenSuSE 11.3 - Configurare retea locala

2010-09-14T10:54:00.007+03:00

Sistemele de operare Linux nu ingradesc optiunile utilizatorilor in ceea ce priveste retelele de calculatoare in care majoritatea computerelor folosesc Windows ca sistem de operare. Astfel, Opensuse 11.3 poate fi integrat foarte usor intr-o retea de calculatoare.
In continuare voi incerca sa ofer un ghid pas cu pas pentru configurarea retelei in Opensuse 11.3. Pentru a configura reteaua urmati pasii de mai jos:

- deschideti Yast si selectati Network Settings:

- in tabul Global Options, de obicei, nu ar trebui sa modificati nimic, setarile fiind cele din imagine:

- in tabul Hostname/DNS introduceti numele dumneavoastra sau al calculatorului in casuta Hostname, iar la Domain Name scrieti numele workgroup-ului din care computerul va face parte.

- Apasati OK.

Dupa realizarea acestor configurari vom trece la setarile Serverului Samba, cel care inlesneste comunicarea cu computerele care folosesc Windows. Pentru aceasta:

- lansati Samba Server din Yast:

- selectati tabul Start-up si bifati optiunile ca in imagine:

- mergeti apoi la tabul Shares si bifati Allow Users to Share Their Directories si Allow Guest Access

- in tabul Identity scrieti numele workgroup-ului in casuta Workgroup or Domain Name si numele dumneavoastra sau al calculatorului in casuta NetBIOS Hostname

- apasati OK. Va aparea un mesaj de avertizare referitor la schimbarea Netbios Hostname pe care il puteti inchideti apasand OK sau YES.

In acest moment inca nu puteti sa accesati reteaua deoarece serverul Samba este blocat de firewall, asa ca trebuie sa modificam setarile din firewall astfel incat sa dam posibilitatea serverului Samba sa comunice cu celelalte dispozitive din retea:

- lansati Firewall din Yast:

- din lista din stanga selectati Allowed Services
- selectati, daca nu e deja selectat External Zone, iar apoi mergeti la Service to Allow, iar din lista selectati Netbios Server si apasati Add. Repetati pentru Samba Server si pentru Samba Client:

- selectati din lista din stanga Broadcast, apoi apasati Add si introduceti valorile din imagine:

Dupa realizarea tuturor pasilor de mai sus este mecesara ori repornirea calculatorului, ori repornirea serviciilor configurate cu ajutorul unor comenzi din terminal. Pentru a ne folosi de comenzi, deschideti un terminal si apoi:

- tastati su pentru a deschide o sesiune ca root si tastati parola de root
- tastati rcnmb restart pentru a reporni serviciile de retea -
- tastati rcsmb restart pentru a reporni serverul samba
- tastati rcSuSEfirewall2 restart pentru a reporni firewall-ul (tineti minte ca in Linux comenzile sunt case sensitive, deci trebuie sa scrieti comanda exact asa cum e descrisa mai sus)

Cam asta ar fi tot. Daca am omis ceva sau inca nu puteti accesa reteaua locala, lasati un comentariu sau trimiteti-mi un email si voi reveni cu completari.
Acum deschideti un manager de fisiere (Dolphin sau Nautilus) si puteti frunzari reteaua locala.

Opensuse 11.3 - instalare driver Nvidia (I)

2010-07-21T15:04:00.003+03:00

O data cu lansarea Opensuse 11.3 Novell a introdus driverul grafic de tip open-source denumit Nouveau care suporta placile grafice Nvidia, AMD si Intel. Insa nu intotdeauna acest driver satisface fiecare utilizator, cum a fost de altfel si cazul meu, in care efectele Compiz erau mult prea lente si nefinisate. De aceea am dezactivat driverul Nouveau si am instalat driverul proprietar Nvidia urmarind urmatorii pasi:

- se downloadeaza driverul Nvidia (acesta, daca nu ati modificat ulterior setarile in Firefox, va fi salvat in /home/nume_utilizator/Downloads)
- se editeaza optiunile de boot prin introducerea optiunii nomodeset la sectiunea Desktop --- Opensuse 11.3 [...] din configuratia bootloaderului: Yast > System > Boot Loader
- se modifica valoarea variabilei de sistem NO_KMS_MODULE_SET in Yes: Yast > /etc/sysconfig Editor > System > Kernel
- se reporneste calculatorul
- dupa repornire se intra in modul consola (Ctrl+Alt+F1) si se intra in contul de root
- tastati rcxdm stop pentru a opri serverul grafic
- se instaleaza uneltele de compilare a kernelului: zypper in gcc make kernel-source
- se instaleaza driverul: sh NVIDIA-...
- dupa instalarea driverului tastati comanda rcxdm start.

Daca urmariti pasii de mai sus totul ar trebui sa decurga fara probleme si sa va bucurati de intreaga putere a placii video a calculatorului dumneavoastra.
Succes!

Opensuse 11.2 - instalare codecuri multimedia

2010-04-15T15:07:00.013+03:00

In periplul prin lumea computerelor, sunt sigur ca toata lumea a auzit cate ceva despre sistemele de operare Linux. Daca ati avut curiozitatea sa explorati putin acest subiect, v-ati dat deja seama ca Linuxul se prezinta sub forma distro-urilor (distributiilor). Din curiozitate, acum aproape un an de zile, m-am hotarat sa dau o sansa Linuxului. Dintre mai multe distributii testate, cum ar fi Mandriva, Ubuntu, Opensuse, Linuxmint, Fedora, cea care mi s-a potrivit si cu care m-am inteles cel mai bine a ramas Opensuse. Pe atunci am testat Opensuse 10, iar in prezent folosesc Opensuse 11.2.

Opensuse 11.2, sistem de operare pe care il folosesc in momentul de fata in mod curent, folosind Windows numai in cazul in care am nevoie de anumite programe care nu ruleaza sub Linux, este un sistem stabil, adresat utilizatorilor de nivel mediu in linux. Eu il folosesc in special pentru aplicatii office, navigare internet si aplicatii multimedia.

Opensuse 11.2 nu se distribuie cu suport total pentru multimedia, in principal din cauza anumitor restrictii impuse de patente software americane sau alte organisme specializate. In cele ce urmeaza, voi incerca sa va arat cum sa puteti deschide aroape orice fisier mutimedia (mp3, wma, xvid, avi etc.) avand sistemul de operare opensuse 11.2 proaspat instalat.

Dupa cum stiti, pentru redarea fisierelor multimedia, aveti nevoie de instalarea unor programele numite codecuri. In Opensuse puteti face acest lucru in doua feluri:

1. Instalarea cu un singur click (one-click-install)

Foarte important: folositi linkul de mai jos numai daca folositi ca mediu de lucru KDE!
Dezvoltatorii acestui sistem de operare au creat un sistem usor de folosit pentru instalarea de programe, oferind posibilitatea instalarii de software printr-un singur click.
Pentru instalarea codecurilor multimedia necesare puteti face click pe acest link: http://opensuse-community.org/codecs-kde.ymp
Decshideti fisierul cu Yast Meta Package Handler, iar daca la un moment dat va aparea o eroare de genul acesta:

doar selectati prima optiune si apoi apasati OK-Try Again.

2. Instalarea manuala a codecurilor

Puteti instala codecurile manual, dar inainte de asta trebuie sa instalati inventarul (repository) 'Packman repository'. Aveti nevoie de urmatoarele pachete:

libxine1-codecs
ffmpeg
w32codec-all
k3b-codecs
lame

Deschideti un terminal si tastati urmatoarele:
sudo zypper in libxine1-codecs ffmpeg w32codec-all k3b-codecs lame
Introduceti parola de root si in cateva minute veti avea un sistem gata sa redea fisiere multimedia.

Opensuse 11.2 - Install multimedia codecs

After a fresh installation of Opensuse 11.2 you need to install multimedia codecs to enable you to open multimedia files. That's because Opensuse doesn't come with a complete set of codecs because of some proprietary software and/or restricitons set by U.S. software patents.

There are two ways for installing multimedia codecs on Opensuse 11.2:

1. 1-click install

First I must inform you that the method presented here is valid only for KDE desktop users! This is the easiest way for the codecs installation. Assuming that you have some knowledge about software installation in Opensuse, all you have to do is to click on the following link: http://opensuse-community.org/codecs-kde.ymp . This will download the yast meta package, after which you need to open it with yast meta package handler. From this point on installation is easy, but if you get an error message like this

just click on the first option and then hit OK-Try Again.

2. Manual codecs installation

You can manually install the codecs. but before this you need to add the Packman Repository to the Software repositories. This is the software you need:

libxine1-codecs, ffmpeg, w32codec-all, k3b-codecs, lame

To install the above open a terminal window and type the following command:

sudo zypper in libxine1-codecs ffmpeg w32codec-all k3b-codecs lame

In just a few minutes, depending on your internet connection your Opensuse 11.2 will be ready to open any multimedia file.

Perhaps a good idea would be to install some nice media players like vlc-player, mplayer, smplayer etc.

Enjoy!

Dezactivare "Driver digital signature enforcement"

2009-09-03T11:36:00.006+03:00

Această opţiune a fost introdusă de Microsoft în sistemele de operare Vista şi Windows 7 ca o măsură de protecţie a sistemului împotriva daunelor provocate de anumite drivere neverificate sau care nu au trecut testul de compatibilitate cu sistemele de operare mai sus menţionate.
Eu insumi m-am intalnit cu o situaţie in care nu am reuşit sa instalez şi să folosesc camera web pe Windows 7, deoarece driverul acesteia nu era semnat digital. Ca de obicei, am apelat la Google pentru găsirea unei soluţii. Din căutările mele m-am oprit asupra a două soluţii, insă numai una a funcţionat în cazul meu.
Aşadar soluţia cea mai bună, dar care este temporară în sensul că e valabilă doar pentru o sesiune de lucru este următoarea:

1. Se porneşte calculatorul şi se apasă F8 pentru a accesa opţiunile de boot pentru Windows 7 sau Vista.
2. Dupa afişarea meniului opţiunilor se va alege "Disable driver digital signature enforcement" şi se apasă Enter.
3. După iniţializarea completă a sistemului de operare se poate trece la instalarea driverelor urmărind instrucţiunile de instalare precizate de producătorul echipamentului. Este posibil ca pe parcursul instalării sa se deschidă un mesaj prin care sistemul de operare vă notifică asupra faptului că driverul nu este semnat digital sau nu a trecut testele de compatibilitate si se alege "Install driver software anyway".
4. Dacă după finalizarea instalării driverului trebuie restartat calculatorul se va avea grijă ca înainte de bootarea sistemului să se apese din nou F8 şi să se selecteze opţiunea "Disable driver digital signature enforcement".
Trebuie reţinut faptul că această soluţie este valabilă doar pentru o sesiune de lucru, astfel că la următoarea pornire sau restartare a calculatorului, dispozitivul astfel instalat nu va mai funcţiona dacă nu se execută procedura descrisă la punctul 1.

Alte soluţii le puteţi găsi aici:

Disable Driver digital signature enforcement

Driver digital signature enforcement was introduced by Microsoft in his new operating systems Windows Vista and Windows 7 as a feature ment to protect the operating system against damages caused by software and drivers that are not digitally verified to the system files.
I myself had to find a way to bypass this feature as I couldn't install my webcam on Windows 7 because the driver was not digitally signed. At that point I remembered that some time before I saw that this feature could be disabled by pressing F8 as computer starts up. The disadvantage is that this is temporary as it is active omly for one session.
So, if you have an old device or one that doesn't have a digitally signed driver and you want to use it in your Vista or Windows 7 do the following:

1. Start your computer and press F8 as your computer starts up to see Windows start up options.

2. As the Windows start up options load, choose "Disable driver digital signature enforcement".

3. After the operating system is loaded you can start installing the not digitally signed drivers (follow the instructions provided by the device manufacturer).

4. If at some point in the drivers installing process you get a message notifying you that the driver you are attempting to install is not digially signed, just choose "Install driver software anyway".

5. If in order to complete the installation your computer needs to be restarted, make sure you press F8 during start up, otherwise the installation might fail.

6. Make sure you press F8 during computer start up and select "Disable driver digital signature enforcement" every time you want to use the device.

Windows 7 - a dispărut unitatea optică (missing CD/DVD-rom unit)

2009-09-02T13:54:00.010+03:00

Zilele trecute am observat că brusc DVD-writerul a devenit inutilizabil în Windows 7 64 bit. Dispăruse complet, iar după o verificare a driverului în Device Manager am observat că acesta nu putea fi instalat de către Windows.
După mai multe soluţii încercate fără reuşită si după câteva căutări pe Google, am găsit solutia. Se pare că foarte multă lume s-a confruntat cu această situaţie în care unitatea optică a disparut brusc devenind inutilizabilă chiar şi în sistemul de operare Windows XP.
Cauza acestei probleme o reprezintă unul dintre regiştrii unităţii optice:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}.

Soluţia constă în ştergerea acestui registru în felul următor:

- Se deschide editorul de regiştri (Registry editor) astfel: Start > Accessories > Run > tastati "regedit" fără apostrof
- Se caută registrul menţionat mai sus (vezi imagine) se selectează, iar apoi din partea dreaptă se şterge LowerFilters (click dreapta pe LowerFilters şi se alege Delete, iar în fereastra următoare se alege Yes).
- Se restartează Windows.

În cazul sistemului de operare Windows Xp trebuie şters LowerFilter şi UpperFilter.

Windows 7 - missing CD/DVD unit

A few days ago I noticed while trying to access my dvd-writer on my Windows 7 pc that it was unusable and disapeared completely from the system. I didn't know what happened so I tried several things to locate the problem and fix it. There was nothing wrong in the BIOS or with the DVD-writer itself (I tested it on Linux) so I figured there was an OS problem. After some research on Google I found that this was a common problem for all Windows operating systems allthough I never ecountered it until now.
The cause for the missing optical drive appears to be this registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}.

To fix the problem (Windows 7 or Vista users) you need to delete one of this registry key value as described below:

- Open Registry Editor:

* go to Start > type "regedit" without the apostrophes in the search box

or go to Start > All programs > Accessories > Run and type "regedit" in the dialog box

- After the Registry Editor opens search for the key described above (see the picture), click on it, go to the right panel and right click on Lowerfilters and choose Delete (choose Yes when Windows asks if you are sure you want to delete it)
- Restart Windows. Now your optical drive should reappear.

In case you run Windows XP and encounter this problem, you need to follow the steps above and delete LowerFilter and Upperfilter.
