Same problem with Xubuntu 14.04.3. I switched back to the xserver-xorg- video-ati driver to see if it fixes the problem.
This was while I was still using fglrx: $ ps aux | grep /usr/bin/X root 1470 0.7 24.3 4415808 1973744 tty7 Ss+ Sep04 65:07 /usr/bin/X -core :0 -seat seat0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch $ lsb_release -a No LSB modules are available.
