Se eu usar DRI_PRIME = 1 após algum tempo, o servidor X irá congelar e não poderá fazer nada, nem mesmo o REISUB funciona.
Aqui está o meu log Xorg completo: link
Mas a maior parte é inútil, aqui está o erro real:

(EE) [mi] These backtraces from mieqEnqueue may point to a culprit higher up the stack.
(EE) [mi] mieq is *NOT* the cause. It is a victim.
(EE) [mi] EQ overflow continuing. 100 events have been dropped.
Eu não sei para qual bugtracker devo relatar isso, ou isso é mesmo um bug?
Eu tenho uma GPU AMD Mobility 7970M.
