http://ubuntuforums.org/showthread.php?t=2130640b) If the command
Code:
lspci | grep -i vga
yields
Code:
00:02.0 VGA compatible controller: Intel Corporation 82865G Integrated Graphics Controller (rev 02)
or similar from the Intel 8xx family you could try to create an /etc/X11/xorg.conf file with the following contents:
Code:
Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "AccelMethod" "uxa"
EndSection
There's a tab in front of the three middle lines. It may or may not give a clearer display than the vanilla install which does not include an xorg.conf. Try with and without, if there's no improvement just delete the file.
/etc/X11 is a protected system directory so operations are only allowed with root rights. One way of creating the file is issuing the command
Code:
sudo <editor_name> /etc/X11/xorg.conf
where <editor_name> is for example leafpad.
The xorg solves among other things the problems of Flash player showing strange green/purple colours and a greyed/blacked-out address in Firefox as seen to the right: firefox_intel_graphics.png
The UXA setting also solves other problems for Intel graphics processors. Use it for general troubleshooting.
