Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

I know this has been touched on by a lot of different threads by a lot of different people, but I can't for the life of me figure out how to fix it.

I'm on a duel boot Windows 8/Ubuntu system and have recently changed my monitor. I am using proprietary drivers and my graphics card is a Nvidia GeForce 660 Ti, the new monitor I am using is a VX2025wm (click here to view the manual).

I know that the monitor works on it's native resolution, because when booting on Windows 8 it automatically adjusts to 1680x1050. I'm not sure if it's worth noting or not, but the old monitor would view GRUB on a higher resolution by default, while this one continues to use low resolution until booted into Windows 8.

I'm really at my wits end, I'm not really used to Ubuntu and I don't have a ton of experience with Linux in general. Any help would be greatly appreciated.

I've included my xorg.conf file

What version of the Nvidia driver are you using? Post the output of dkms status. Have you tried installing an experimental one in the "Additional Drivers" system application? –  gertvdijk Dec 31 '12 at 12:56
    
nvidia-current-updates, 304.51, 3.5.0-21-generic, x86_64: installed I installed the experimental one last night, and it did nothing to change the problem, so I went back to current-updates. –  Unlimit Carries Dec 31 '12 at 12:59

Working on it all day, I've come to the conclusion that problem lies solely in the monitor, VX2025wm's have a history of problems for the EDID and DVI Input, such as not showing native resolution, Signal Not Found errors, and a bunch of other messy little things that aren't conducive to a fluid computing environment.

The solution lied in adding a Custom EDID to the xorg.conf file:

Option         "CustomEDID" "DFP-0:/etc/X11/viewsonic.raw"

For this specific monitor, I was able to find the EDID here: http://blog.komeil.com/2008/06/fixing-edid-dvi-monitors-no-signal.html

I hope this helps anyone who is having problems with their native resolution and is certain that their Graphics Cards / Drivers are not the problem.
