Comment 10 for bug 93156

Sorry I haven't got back to you after asking for that. Do you notice how the modes advertised do not include 1440x900? nv doesn't have an ignore edid option, so the panel's report is likely conflicting with your xorg.conf settings. As it happens, EDID simply can't represent 1440x900.

As it happens, I'm running 1440x900 on gutsy with nv. I'll attach my xorg.conf in case it has any secrets you find enlightening, but I'm not sure why it works. If you could try with Gutsy, that might enlighten.
