I have a problem were the highest resolution I can get is 1360x769, this is a 22 inch LCD monitor with a native resolution of 1920x1080_60 I have tried numerous drivers but nothing changed I tried editing the xorg.conf scipt with no success (I am a noob with linux though). Running many commands in terminal witch I got from people with similar problems only gives me errors like "Failed to get size of gamma for output default. I get edid checksum is invalid error on boot down also. I think there maybe a communication problem between my screens EDID and ubuntu although xp and windows 7 detect my screen without any errors and automatically set native resolution. also when I am installing ubuntu I get a horrible screen flashing every few seconds until I have installed the nvidia driver. pc specks if it helps x64 os, mainboard N68PV-GS, 4 gig ram, AMD Phenom(tm) 9350e Quad-Core Processor × 4, Nvidia Geforce gts450 512mb, hard drives set up in a onboard nvidia raid array striped. realy need to get a better resolution, 1360x769 does not look nice on a 22 inch screen. ty
Following options from X Config Options chapter of the proprietary Nvidia driver documentation might be helpful:
This option forces the X driver to accept an EDID even if the checksum is invalid. You may specify a comma separated list of display names. [...]
This option controls whether the NVIDIA X driver will use the HorizSync and VertRefresh ranges given in a display device's EDID, if any. [...]
This option provides fine-grained control over each stage of the mode validation pipeline, disabling individual mode validation checks. This option should only very rarely be used. [...]
But be careful and don't try all possible options, just because they sound interesting.
