Public bug reported: After a clean Quantal installation in a Toshiba A75-S229 notebook, Unity runs VERY VERY slow, including several seconds to just draw a warning box or the shutdown box. 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 ** Affects: xserver-xorg-video-ati (Ubuntu) Importance: Undecided Status: New ** Tags: 200m ati composite radeon slow -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/1074063 Title: Very slow composition with ATI 9100 IGP and Quantal 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/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
