Description CrystalCowboy 2004-06-10 06:09:08 UTC
2004-06-08 Attempting to get Xwindows display working properly on a
Commell LV-671NSMP motherboard. http://www.commell.com.tw/Product/SBC/LV-671.HTM
Chipset: Intel 855GM/GME GMCH built-in Intel Extreme Graphics 2

Red Hat Enterprise, SuSE 9.1 and Fedora Core 2 all fail out of the box to
configure any resolution greater than 640x480. The most extensive testing was
done with Fedora Core 2, kernel 2.6.5-1.358, xorg-x11-6.7.0-2.

In the X.org log file, when the driver polls the video BIOS for modes, they all
come out filled with 0 except for the 640x480 mode.
Xorg log file: http://staff.chess.cornell.edu/~schuller/Xorg.0.log.clean
configfile: http://staff.chess.cornell.edu/~schuller/xorg.conf

Tried 855patch and 855wrap:  http://www.chzsoft.com.ar/855patch.html
These did not fix the problem. Resolution is still 640x480.
Comment 1 CrystalCowboy 2004-06-11 03:08:06 UTC
Problem resolved.

Thanks to Christian Zietz for pointing out this line in my X log file:
"Size of device LFP (local flat panel) is 640 x 480"

Down in the BIOS, 'Advanced Chipset Features', there is a line for "Boot
Display".  Choices include AUTO, CRT, LCD, CRT+LCD, DVI, TV, CRT+DVI
It occured to me that in this context, LCD did not refer to the VGA monitor I
had attached, but to the internal LVDS connector. I changed the Boot Display
setting from AUTO to CRT and I now have higher resolution.
Comment 2 640x480 Resolution is AWESOME 2005-09-23 11:59:59 UTC
Actually, you need to channge the LCD type to something other than 1 or 2 even 
if you change the Boot Mode from "auto".  It'll still lock into 640x480 
resolution if the type=CRT but the LCD mode is still "1".
