Ikbel, This is a common issue right now; lots of people reporting it (see bug #638725, bug #608361, bug #616997). From bug #608361, Vish makes this recommendation, from the command line execute: $ ubuntu-bug xserver-xorg-video-<driver>
where <driver> would correspond to the graphics card your system has. Once you've done that, you need to "also affects" Unity. Then come back to this bug and add a comment with the new bug number.
