Bumping priority to high since a number of people are reporting this or similar issues. I'm suspecting though that it's not a bug in the code but rather something else in the system that leads to the crash. Occurs during object destruction.

Happened to me after changing my display properties in Catalyst Control Panel and then closing the control panel.

I've got two monitors, and on restart Natty generally resets me to one monitor. I used to go into the Catalyst Control Center and reset my two-monitor setup there (which would then be reset to one monitor on next restart). This last time I restarted, the Monitors control panel opened automatically (never done that before). I used it instead of amdcccle to activate my second monitor, rearrange the two monitors' positions, and apply changes. Monitor setup was correct, but amdcccle crashed immediately.

Same issue amdcccle crashes when I try to enable my second monitor. The configuration never gets written.

same here with ati HD5700

Same for me with a Radeon 5770 and a 5870.
I have all the latest updates installed also for Oneiric.

Also affects Oneiric 32bit and 64bit.

I've been able to workaround this problem by cleanly uninstalling fglrx and reinstalling some components as detailed here.

Now I have the free radeon driver running a dual monitor configuration complete with 3D effects from Compiz.

Given that the proprietary AMD drivers would not work for either my Radeon 5770 or 5870, this will do me fine.

I hacked a crude workaround:



sleep 1
xrandr --output DFP1 --auto --right-of DFP2

chmod ogu+x

and put it in the Autostart of the desktop environment

Hope that's fine until the amdcccle issue is fixed.


PS: really Compiz with the free driver - sounds to good to be true. Having spend too much time to get my system to start reasonably well: I have a AMD RADEON HD 6450 . Would it work with the free driver and 3D as well? Anyone tried it yet?

Thank you.
