I had nothing but trouble with the free driver with a kabini APU. Hibernate would give a black screen on resume. The "Dim screen after an inactive period" (whatever it's called) would dim it further until the backlight turns off everytime the period elapses. And a lot of programs like the adobe flash plugin and other players, and games would show video that I may have watched even days before but it's still on video memory when started. The only problem I've had with the proprietary driver (which may be realted to your problem) is that if you use a premptive kernel it causes a LOT of errors to be written to the syslog which makes the desktop very unresponsive. That's because it calls functions that should not be called with preemption enabled. If that's your problem you'll see errors on the syslog and I posted a patch that disables preemption before calling those functions. It's on a VLC bug (cause at first I tought it was a VLC related) and I recently noticed that I still get the errors if I switch between X sessions with CTRL-ALT-Fx so it's incomplete but it makes things much better. I will update it and post it on the right bug when I get around it. -- Fernando Rodriguez
