Comment 5 for bug 1174278

JG, the solution you linked is very similar to what I did (building latest fglrx .deb packages + downgrading the intel video server). Please report if it works, since the linked .deb for the intel server seems to be the same version as the one provided in raring by default (I have had success installing the 2.20.2 version, along with libudev0, from Quantal's repositories)
