When you install CentOS 5.4 (and probably this will also apply to Scientific Linux 5.4) on a laptop with an Intel GMA X3100 Gfx chipset, you get a display where things are out of line (like resolutions of 1024x768 on a screen of 1280x800). See this example: http://img41.imageshack.us/img41/313/screenshotwithc53xorg.jpg It appears that this is a problem related to the system thinking there is an external display connected where it isn't.

Add the following lines to solve the problem: - - - - - - - - - - - - Section "Device" Identifier "Videocard0" Driver "intel" Option "monitor-TV" "TVOutput" <=== this one!!! EndSection Section "Monitor" <=== this one!!! Identifier "TVOutput" <=== this one!!! Option "Ignore" "true" <=== this one!!! EndSection <=== this one!!! - - - - - - - - - - - - Regards, Patrick -- All views, opinions and alleged facts expressed by this tactless moron should be taken as good natured and friendly unless specifically stated otherwise.
