[Bug 1293384] Re: Compiz CPU usage dramatically increased in Ubuntu 14.04


Same here, on a desktop with 14.04 64 bit with default DE (Unity), using
a  gtx 260 with the recommended proprietary and tested driver, with all
updates, using 2 external monitors.

I've tried turning off features/special effects in compiz to see if
there was any change but the problem still persisted. It helped a bit
but compiz was still eating abnormal amounts of cpu.

I've found 3 solutions thus far that solved problem but I'm not sure if
it'll work for anyone else:

1. Switching to the open source driver (in my case, the nouveau driver because I'm using an nvidia card)
2. Switching the DE to something that isn't unity
3. Disabling my 2nd monitor

Obviously, the first option was ideal as everything just worked and I
didn't have to sacrifice a monitor or switch DE's.
