<pre>Hello,
I do have same issues wiht my Ubuntu 14.04 on my Lenove T410 ThinkPad with
external 20" LCD Monitor.
During freeze, occurs after 5 minutes or 2 days, the laptop does not respond
to any input on the current Screen, but the programs are still running in
background, e.g. sound and movie are still playing.
CRTL+ALT+F2 is still possible and it is possible to do a sudo services lightdm
restart (<- without any help).
