Let me clarify. The slowness is present after waking up from suspend OR if I boot up using vblank_mod=0. > >> So, this is rather strange.

In fact, right now, I've been probing the quad pipe message and it seems to vary. The last two boots with 2.6.38-2 kernel lead to a reported number of 3. After the resume the number remains 3: $ dmesg | grep quad [ 9.554083] [drm] radeon: 3 quad pipes, 1 z pipes initialized. [ 173.492317] [drm] radeon: 3 quad pipes, 1 z pipes initialized. But the slowness is still present and almost crippling... -- To UNSUBSCRIBE, email to debian-x-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
