With an old HP Compaq PC, Pentium III 800 MHz with 512 MB RAM and a Technisat 'AirStar 2 PCI' TV card, my wife records/watches TV in Windows XP by the DVBviewer program. The picture is very good and smooth even if it quickly changes as by viewing sport. This holds also now after I had to remove the graphics card to be able to install Ubuntu 12.04. But with Linux programs Me-TV or VLC, video is shown jerkily. According to Check if my 12.04 has graphics card drivers and find the right ones I get:

user@CPU:~$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation 82815 Chipset Graphics Controller (CGC) (rev 02)

Now the Intel driver for the same chip of the PC board is shown in Windows Hardware Manager. I do not see why the graphics does not work in Ubuntu so well as in Windows. In the Me-TV, I have tried all the the video drivers there; a difference is hardly observable, the 'xshm' maybe is the best.

I intend to try it with different graphic cards. For the Matrox G450-32 that I have used in the PC until recently I cannot find a driver for Linux. I intend to try my VGA Gainward BLISS 9757 - FX5200 that I have successfully used in a similar Pentium IV PC with Windows. I hope I may use the driver for Nvidia from here (files nvidia-173-updates-dev_173.14.35-0ubuntu1_i386.deb and nvidia-173-updates-dev_173.14.35-0ubuntu1_i386.deb). The question is:

If I may use them for my Ubuntu 12.04 (Pangolin) while the page title is about drivers for more recent Quantal? Is *.deb for 'debian' sufficient?

Thanks!

I like Occam's razor as a general guiding principal for this question, but to be specific about your case, the possibilities are: 1) Install the Nvidia 'version 173' graphics driver from the Software Center. 2) Look for a graphics driver at the Nvidia website. For example, Linux Display Driver - x86, Version: 173.14.36 Certified. Yes, .deb file is OK in Ubuntu or else download the Linux binary and compile it yourself. 3) try a possibly incompatible driver for Quantal (maybe it won't work though). –  karel May 19 at 3:47
    
@karel :You have encouraged me and I have found linux drivers for my well-tried Matrox card, at matrox.com/graphics/en/support/drivers/download/?id=143 . Are the drivers from 2006 and included install.sh probably usable yet in Ubuntu 12.04? Thanks! –  Tomas Peceny May 19 at 16:52
    
@karel: I thank you very much for your effort; I am not experienced with Linux system; I have unpacked the matrox_driver-x86_32-4.4.0.tar.gz (by Krusader) as a matrox_driver-x86_32-4.4.0 directory containing the install.sh file. I do not know, what <mga_filename> set in the <pre>. mgadrivers –  Tomas Peceny May 21 at 18:16
    
@karel: Correction of this comment (I have used Enter key and the concept was sent before I aimed.) I thank you very much for your effort; I am not experienced with Linux system; I have unpacked the matrox_driver-x86_32-4.4.0.tar.gz (by Krusader) as a matrox_driver-x86_32-4.4.0 directory containing the install.sh file, because I do not know, what <mga_filename> I should set in the <pre> tar xvzf <mga_filename>.tgz </pre> command. It creates the /mgadrivers directory? Please advise me. I need only one monitor, the only purpose is to achieve smooth TV displaying. Thanks! –  Tomas Peceny May 21 at 18:39

If you just leave the install.sh file unchanged, then it will run and it won't find the path to Xorg, so it will prompt you to input the path to Xorg yourself, which in your Ubuntu 12.04 is /usr/bin/Xorg and then maybe once it has been told the path to Xorg the Matrox driver will install OK. –  karel May 25 at 17:44
