Just a small "happens to me to" comment, with one small extra detail about kernel versions:

After Ubuntu 12.04 with automatic updates picked up kernel 3.2.0-39-generic, all computers on our campus (20+ with the problem) with Pentium G840 for CPU (Intel i915 graphics) started having that problem.

We resolved the problem temporarily by installing linux-image-3.2.0-38-generic and removing linux-image-3.2.0-39-generic.

The old fix described in the kernel bug report was not working for us (kernel command line option i915.i915_enable_rc6=0)
