Compiz are consuming more than 100% of my cpu

Compiz are consuming more than 100% of my cpu, without any window opened. That's starts without any changes on the configurations or effects of Compiz. My notebook have a core i3 - 4x 2.20GHz, Unity 7 and ubuntu 16.04. I'm newbie at the Linux world and i don't know what can i do to fix it.

Just to confirm, this is a fresh installation of Ubuntu 16.04? We'll try to fix the problem with smaller measures, but a system upgrade may fix this issue. Let's hope it doesn't come to that, 16.04 is the most recent LTS version I believe.

Me personally, I would remove Compiz and see what I had and go from there.

Typcailly compiz eating is caused by a borked gpu driver (or no driver at all)

To see what the current driver is and the card you have, open a terminal and run:

Code:

lspci -vnn | grep VGA -A 10

shows.

Also you can see what is what with

Code:

glxinfo

but that command is part of a package that needs to be installed,
to install the package for that command run

Code:

sudo apt-get install mesa-utils

post back the results if you can, please.

Thanks for the help. I think that i've installed the 16.04 1 year ago, but i update it whenever i can. I'm using a Sandybridge and already have the mesa-utils. Now i'm using the metacity, but with him i'm having problems with execute some programs. WIthout the compiz, evertything are running ok, except some programs. Sorry for my english, i'm learning yet.

DeadFlowr, here the result of the command:
