I recently updated my Debian to the latest version of Jessie. Whenever I search for an app and click on one of the suggestions in Activities, the display is frozen, but I can still see the mouse moving.
I can only recover from this with a reboot.
I have tried the free and proprietary graphics drivers and they both have this issue.
I have looked at the
syslog and found the following message around the time my machine was frozen:
BUG: unable to handle kernel paging request at (some address)
I was wondering if anyone has had the same issue and/or knows its solution.
