Fix high cpu usage on Linux Ubuntu 14.04 LTS with Unity

Lots of people reporting very high cpu usage on Linux Ubuntu. I have got the same problem (but I can not report the bug, because I have no access to your support forum, neither I can not contact you directly, because the contact forms are not working...).

Example configuration:
OS info: Linux-3.16.0-77-generic-x86_64-with-Ubuntu-14.04-trusty
CPU info: Intel(R) Core(TM) i5-4210U CPU @ 1.70GHz Cache: 3072 KB Cores: 2
Installed RAM: 8097920 kB
DL driver version: 1.3.52
Hardware: ACER Aspire v3-371
Connected Devices on the docking station: USB-Mouse, USB-Keyboard, HDMI-Monitor (1920x1080), DVI-Monitor (1920x1080), RJ-45 Network Cable
CPU-Usage: 15-60%

Removing the DVI monitor connection drops the cpu usage down to 0.7% (The system crashed after disconnecting the cable, but that's another bug, I guess).

Please fix this bug. Thanks.
