Comment 18 for bug 957298

This doesn't appear to actually be fixed and the workaround of running the below command no longer works on Ubuntu 13.04 with linux 3.8.0-18. Is there a way to get the fix from 3.9 into 13.04? My system is so unresponsive at times, and it happens fairly often, that I can't do anything with the mouse.

echo N> /sys/module/drm_kms_helper/parameters/poll
