Public bug reported: I have Ubuntu 14.04 installed on a Lenovo X1 Carbon series 2. Whenever I lock my screen, compiz's CPU usage goes through the roof and it causes the CPU fan to spin up to max speed. I SSH'ed into the machine while it was locked to verify that it was indeed the compiz process causing the high cpu usage. When I unlock my computer, everything goes back to normal.
I've looked at https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/969860, which seems related but that is for fglrx. This laptop has an Intel Haswell gpu.
