Bug Description
I've been running Kubuntu 14.04.2 LTS for about a year with no problems. Problem started about 3 months ago or so.
- The screen usually locks up when using Firefox, today it happen when I switched windows from Firefox to Konsole (the GUI app). The screen locked half way switching the window borders from blue to grey. The konsole window border on my right monitor is was grey, is now locked faint blue and should have turned to full blue. The Firefox window on the left monitor was full blue, is now slightly going to grey and locked right there and then.
- When the system is locked, which happens every two or three weeks, I can sometimes change to text console but not always. Currently I cannot access console, but I can log in to the box through SSH. Screen blanking (power save) doesn't work when the screen locked. When my box locks up, I usually run full patching before power cycle, some messages in log files may be caused by that.

I disabled desktop effects for the moment, because some articles on Internet point in that direction and also the lock up clearly happened during the fading effect from one window to the other, as described above.
