Similar problem on Lenovo T420. Sometimes switching to console and back to X seems to wakeup everything. Normally the mouse can still move on the screen, just nothing happening.
Looking through my logs i found a couple of error messages in syslog. > Jan 7 21:06:29 t420 kernel: [ 225.148702] [drm:i915_hangcheck_hung] *ERROR* Hangcheck timer elapsed... GPU hung maybe someone else can confirm if they have seen the same, also planning to disable Bluetooth as this has given me problems before. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/987498 Title: Unity/compiz freeze but mouse still move To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/987498/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
