I have a vexing problem that has wasted most of my morning. When I try to make an R plot, I get logged out of my machine immediately. I tried
xclock
and the same thing happened - immediate log out.
Some details:
Graphics card: 03:00.0 VGA compatible controller: NVIDIA Corporation GK110 [GeForce GTX Titan] (rev a1)
OS: Ubuntu 12.04.5 LTS, x86_64
Currently using NVIDIA proprietary driver version 340.46 (http://www.nvidia.com/download/driverResults.aspx/78469/en-us)
I tried purging the Ubuntu graphics drivers, uninstalling NVIDIA, reinstalling NVIDIA, and rebooting, and I'm back where I started. X seems to load fine, I can use Firefox (and play YouTube videos) with no trouble.
But God help me if I type "xclock" in the terminal. Also, when I try and plot something in R, as in
plot(1:10)
The plot window shows briefly, then the screen goes black, and I'm sent right to the login screen.
Turns out upgrading to Trusty Tahr and reinstalling the NVIDIA drivers solved the problem handily.
