(Get the code!)
Mint 17.2 64-bit version,
Cinnamon 12.6.13.
I use the onboard graphics on an Asus 7170 mobo (No NVDIA).
Symptoms are random but the most common triggers are scrolling in firefox (all pages intermittently but almost always in facebook), entering text, especially in FF or in Netbeans.
Screen goes blank for a couple of seconds, then the logon/welcome screen is displayed and a timer makes me wait 10 seconds before automatically logging me back in.
After logging back on all windows are closed and work is lost.
Don't know if it's related but graphics also display strangely, usually after I scroll and especially in text editor. White space in the window goes dark with purple/pink horizontal lines. Keyboard navigation (typing or arrow keys) returns graphics line-by-line.
$ uname -a

I update kernals when they become available, 3.16.X, 3.19.X and 4.2.X they all have the same problem.
All the bugs described here are just what I am experiencing: https:/
