[School-GNU-Linux] Graphics Configuration Problems

Hello List,

Most of the graphics related problems are due to choosing wrong
display driver for XServer.

here are some tips for finding out the correct driver for xserver. (
to run the commands mentioned here, switch to command mode
(Ctrl+Alt+F1) and login as root. To switch back to GUI mode use
Ctrl+Alt+F7)

To find which graphics card your system has, execute the command
"lspci | grep VGA" at the root prompt. You'll get a line 'VGA
compatible controller' followed by the description of your graphics
card.

If you see a number Intel 82810 to 82865 the driver to use is i810.
For any latest graphics cards you can choose the VESA driver. If the
card you have is Nvidia or Geforce, choose nv as the driver.

If you want to find out the cards supported by a particular driver,
use the command
"man driver-name"
for example, if you want to find which cards are supported by the nv
driver, give the command "man nv".

If you have an intel based graphics card or a graphics card with no
built-in memory, set video memory of bios to atleast 8MB and set the
video ram to 8192 in the xserver configuration screen.

You can always reconfigure the graphics with the command
dpkg-reconfigure xserver-xfree86

Hope this Helps,
