I'm having trouble getting a cheap LCD 18.5 inch monitor to work properly with Ubuntu 10.04.1. The brand is "Great Wall". It's supposed to have resolution 1366x768, but I can only set it as 1360x768.
I have Ubuntu installed on an external hard drive, and for what it's worth, at work I have a nicer 18.5 inch monitor, HP brand, also 1366 x 768, and it works perfectly when I boot there.
I have tried using cvt, but it gives me this:
$ cvt 1366 768 # 1368x768 59.88 Hz (CVT) hsync: 47.79 kHz; pclk: 85.25 MHz Modeline "1368x768_60.00" 85.25 1368 1440 1576 1784 768 771 781 798 -hsync +vsync
I managed to add this 1368 x 768 mode to my xorg.conf, that I generated using some command I can't remember now (sorry!), but it looked just as bad as 1360 x 768, so I undid the change.
I can live with it for watching video, but any extended OpenOffice session makes me want to poke my eyes out :)
I'm using Intel graphics: 00:02.0 VGA compatible controller: Intel Corporation 82915G/GV/910GL Integrated Graphics Controller (rev 04)
Any suggestions? Can I get the EDID out of the HP monitor and try to override it for the monitor at home? (and cross my fingers)
EDIT: I have added the xorg-edgers PPA, and it didn't make any difference. Here is my Xorg.0.log in case it helps: http://clippy.cz.cc/index.php?show=124
EDIT2: I got the modeline for 1366 x 768 on the HP monitor at work. Going to try it at home and see what happens. This is what I got from the Xorg.0.log when booting the computer with my external HD with Ubuntu 10.04:
Modeline "1366x768"x0.0 85.50 1366 1435 1578 1790 768 771 781 798 -hsync +vsync (47.8 kHz)
EDIT3: Tried the modeline above, and it gave similar results to modelines for 1360 and 1368. But then I noticed something, so see below for the answer to my own question :)
