Q:

compiz high resource utilization in virtual machine

I am using ubuntu 14.04 virtual machine and in that compiz process is using high CPU resource around(200 to 300). And due to this my mouse and keyboard are getting sync issue(means keyboard will not respond for few second).

A:

I too faced same issue, so  I have switched back to GNOME Classic (Metacity) by installing the following package:

for Ubuntu 14.04:
apt-get install gnome-session-fallback 

for Ubuntu 16.04:
apt-get install gnome-flashback 

Then there is no trace of compiz in the process list...
