Is it really fixed ? It seems that it affects only some notebooks, e.g. many IBM Thinkpads. These models were useless for a long time and debian X > 6.8.2. If your model was affected and it seems to be fixed now, I will try it. Then I could also confirm that this bug is fixed. (I use a radeon M10 / T41p) [Is there any problem to update to xserver-xorg-video-ati 6.6.0, which is stil released and seems to be more bug free.] Regards, Nils
