Bug#571956: I've fixed it

[ceco m]

I managed to fix it, i've downgraded the radeon driver from 6.12.99git to
6.12.4-3 in unstable, now everything is fine! :)
And another thing i haven't compiled the radeon driver myself it was from a
package in a ubuntu PPA repository.
Sorry to bother you guys and thank you for your time. :)
