Public bug reported: Occasionally when resizing windows on Xubuntu 14.04, the desktop freezes and does not respond to keyboard presses or mouse clicks. When this happens, it is possible to switch to a virtual terminal and execute shell commands. This freeze does not happen everytime a window is resized, but it does happen approximately once per week.
The output from dmesg shows: [162720.545967] [drm] stuck on render ring [162720.546032] [drm] GPU crash dump saved to /sys/class/drm/card0/error ...
