I'm glad I found this thread. I'm having the same problem, with a wrinkle: I'm getting "OpenGL renderer string: Software Rasterizer" from glxinfo no matter what I do, even though my Xorg.0.log seems to indicate that DRI is loading fine--at least I don't see any obvious errors.
Changing from EXA to XAA helped a lot, but I still can run my CPU up to 100% in 40 seconds running just glxgears, the LXDE desktop, and one terminal window. I'm on a Radeon Mobility M6 LY and a custom-built kernel from Ubuntu source. Hardware is a Sharp PC MM 20 with Transmeta Efficeon processor. I've attached my Xorg.0.log with details, if anyone would care to have a look. My xorg.conf is in the following post. ** Attachment added: "Xorg.0.log" http://launchpadlibrarian.net/29697950/Xorg.0.log -- very poor Xorg performance on various older graphics HW - XAA solves this https://bugs.launchpad.net/bugs/363238 You received this bug notification because you are a member of Ubuntu-X, which is the registrant for xserver-xorg-driver-ati. _______________________________________________ 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
