Ubuntu 13.04 cannot detect 2560x1600 monitor with Nvidia Titan GPU

Asked by earthforce_1 on 2013-04-24

Did a completely fresh install of the 13.04 Raring Ringtail release. I have an Nvida Titan GPU and a 30" 2560x1600 monitor that was detected and configured correctly with earlier releases using my previous ATI HD7970 GPU that I had to replace due to a worn fan.

Unfortunately, I am stuck in 1024x768 mode. System settings seems to think I am using a laptop and only offers 1024x768 or 800x600. Even the aspect ratio is wrong, as both are 4:3! It should come up with or at least offer 2560x1600 which is my Dell 30" monitor's native resolution.

How can I fix this?

I was able to solve the problem by using the latest nvidia provided 313.26 .run file driver and bypassing the Ubuntu package manager. I had to ignore the warning that the distribution provided pre-install scripts failed.

The procedure is:
Download NVIDIA-Linux-x86_64-313.26.run from the Nvidia website
chmod +x NVIDIA-Linux-x86_64-313.26.run
<CTL><ALT>F1
Log in
sudo service lightdm stop
sudo init 3
sudo ./NVIDIA-Linux-x86_64-313.26.run
Accept EULA
Ignore warning about pre-install scripts failing
Choose yes for all other options
sudo service lightdm start
