This bug effected/effects me as well (i5-2520M), but this is a duplicate
of https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-
intel/+bug/882349 and you can work around it with the instructions here
:https://bugs.freedesktop.org/show_bug.cgi?id=39730
Robvdl says a proper fix is headed upstream though.
I was able to do the "one shot fix" by compiling the latest intel-gpu-
tools from git, then running as root:
sudo ./intel_reg_write 0x9404 0x00001000
