Leonardo SIlva Amaral, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .
If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report: apport-collect -p xserver-xorg-video-ati REPLACE-WITH-BUG-NUMBER Please note, given that the information from the prior release is already available, doing this on a release prior to the development one would not be helpful. Thank you for your understanding.

CPU burns-out to 100% (And the multithread secondary cpu got overloaded too). Any DM that uses Composition show this issue. Tested with Cinnamon. Cinnamon2d just dont run and keep as Cinnamon 3D. A workarround (Not well a workarround but a "Way to survive") is run Cinnamon and in a gnome-terminal run "metacity --replace&", but this kill Every window management, forcing me to use the terminal to launch applications. Tryed Quantal version of Xorg and now testing without success xorg- edgers versions. The fglrx driver existent in ppas and oficial repo dont support this board, since the last catalyst driver supporting it v8. Some outputs, since ubuntu-bug doesnt allow reports using ppas versions: leonardo@jarjarbinks:~$ sudo lshw -sanitize | pastebinit - http://paste.ubuntu.com/1324069/ leonardo@jarjarbinks:~$ pastebinit /var/log/Xorg.0.log http://paste.ubuntu.com/1324070/ leonardo@jarjarbinks:~$ dmesg | pastebinit - http://paste.ubuntu.com/1324073/ leonardo@jarjarbinks:~$ LANG=C apt-cache policy xserver-xorg-video-radeon xserver-xorg-video-radeon: Installed: 1:6.99.99+git20120928.e8cb0b72-0ubuntu0sarvatt Candidate: 1:6.99.99+git20120928.e8cb0b72-0ubuntu0sarvatt Version table: *** 1:6.99.99+git20120928.e8cb0b72-0ubuntu0sarvatt 0 500 http://ppa.launchpad.net/xorg-edgers/ppa/ubuntu/ quantal/main i386 Packages 100 /var/lib/dpkg/status 1:6.99.99~git20120913.8637f772-0ubuntu1 0 500 http://br.archive.ubuntu.com/ubuntu/ quantal/main i386 Packages To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/1074063/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
