Comment 2 Diego 2009-09-10 14:44:17 UTC
Just to be clear:

F11 works in every case.

Rawhide Radeon Test Day (09/09/09):
- glxgears no KMS: OK
- compiz no KMS: OK
- glxgears KMS: OK
- compiz KMS: freeze after ~2 seconds

KWin compositing seems to work on 24/09/2009 Rawhide KDE Live CD Nightly build:
so probably this is fixed for Compiz too... I'll let you know.

Confirmed, also Compiz works without lockups now.
