Title:
Intel DRM GPU hang in Kubuntu 15.04
Status in xf86-video-intel:
Invalid
Status in xorg package in Ubuntu:
Incomplete
Bug description:
Intel driver hangs every time KDE uses one of the special system
effects. I can reliably reproduce it by pressing "Alt-Tab", for
example. The only fix is to reboot the computer.
Kernel version:
$ uname -a
