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
Tried 855patch and 855wrap: http://www.chzsoft.com.ar/855patch.html
These did not fix the problem. Resolution is still 640x480.
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.
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".
I am glad to see that how passionately you guys are working with together to help others and even to the readers in finding the solution of different bugs. I have also found http://apps.quibblo.com/story/c5LV-7sC/Excellent-Ways-To-Improve-Your-Time-Management-Skills-in-College article the solution of many of my assignment errors and bugs through this source.
