Before removing Compiz you might wanto to try and reset it
1.Press Alt + ctrl + F1
2.Login using your username and password
3.Reset compiz by executing gconftool-2 --recursive-unset /apps/compiz-1
4.Reset unity , by executing unity --reset
5.Optionally you can reset launcher icons by executing unity --reset-icons
6.Press Alt + ctrl + F7 to get back to login screen. However I recommend a restart by executing sudo reboot
. Let us know if it worked.

To remove compiz and compiz packages type this in a terminal:
sudo apt-get purge compiz compiz-plugins-main-default libcompizconfig0
Warning: Removing compiz also removes the packages unity & ubuntu-desktop.
Warning: Removing libcompizconfig0 also removes ubuntu-tweak.
Thus you will lose the ability to log into the unity or unity-2d desktops.

sudo add-apt-repository ppa:xorg-edgers/ppa && sudo apt-get update && sudo apt-get dist-upgrade -y
A message was showed to me, so I did follow the tip and create a xorg.conf with with content:
Section "Device" Identifier "intel" Driver "intel" Option "AccelMethotd" "uxa" EndSection
Just it!
I hope it helps!
Thanks
