I have Ubuntu 14.04. Today suddenly it started to log out abruptly every 5 minutes. It was running fine before. but now I cannot even read the error messages.. what should I do..

Edit: I noticed that it happens when i run applications like firefox or CompizConfig settings manager.

My graphics card driver is Nvidia binary driver- version 331.89 from NVIDIA-331, graphic cards on my system are Intel Corporation 4th Gen Core Processor Integrated Graphics Controller and Nvidia GEFORCE 750M. Currently I am using intel

Had the same problem. Seems to me that this is due to a potentially incorrect update from this Monday. Please try to update your xserver-xorg-video-intel, a new version has been released now, maybe they realized this issue.

sudo apt-get install xserver-xorg-video-intel

I did this, so far so good, I could not yet reproduce the crash.

I am new to ubuntu too, but you should check into the system config, then shine&lock, inside there should be turn off the screen then choose the time you want.

See if that helps.
