--- Comment #4 from Frederic Crozat fred@crozat.net 2010-08-17 12:18:00 PDT --- hmm, trying mesa git with kms is even worse ATM : gnome-shell (2.29.1) doesn't respond to anything and does refresh correctly ; kernel states : drmRadeonCmdBuffer: -12. Kernel failed to parse or rejected command stream. See dmesg for more info.
