Same over here. With a fully updated stock Ubuntu Jaunty on a T43p / i386 with a 01:00.0 VGA compatible controller: ATI Technologies Inc M22 [Mobility Radeon X300] graphics card, the "radeon" driver and the packages linux-image-2.6.28-11-generic 2.6.28-11.42 xserver-xorg 1:7.4~5ubuntu18 xserver-xorg-video-radeon 1:6.12.1-0ubuntu2 and an empty xorg.conf. Problems were: * random freezes with 3D applications [both with compiz enabled or disabled, DRI & AIGLX were always enabled] * poor Compiz performance Both issues were solved by upgrading to linux- image-2.6.29-02062904-generic from the above kernel PPA source. I wonder whether the relevant kernel changes will be backported? I could help to track down in detail what caused the issue. The alternative of disabling DRI for all affected users as described in comment 30 isn't particularly nice. Those whose problems could not be solved by a kernel upgrade seem to be affected by random freezes even when no 3D application runs. Maybe those people could describe their configuration, and used packages in depth? Especially which kernel/xorg combinations work, and which don't. Also, focusing on "future" technologies [recent DRI releases, EXA] instead of downgrading X.Org would be nice, since XAA or support for the old DRI architecture will be discontinued. Also, please try to start with stock packages and _systematically_ vary the kernel/xorg versions. -- [RV250] Kubuntu: X Freezes with Radeon driver EXA/XAA Composite https://bugs.launchpad.net/bugs/348332 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in ubuntu. _______________________________________________ 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
