I believe the pain is self-inflicted in Ubuntu. The responsible patch is 104_use_exa.patch. I hope that upstream will help us out of this with a proper patch that selects EXA by default but drops back to XAA in low- memory situations.
Stay tuned. BTW, if there is anybody who can write proper code, can you pleaes take a look at http://bugs.freedesktop.org/attachment.cgi?id=26476 (104_use_exa.patch) and make it work more like http://bugs.freedesktop.org/attachment.cgi?id=25890 ? ** Summary changed: - [r100-rv200] very poor Xorg performance - XAA solves this + very poor Xorg performance on older graphics HW - XAA solves this ** Summary changed: - very poor Xorg performance on older graphics HW - XAA solves this + very poor Xorg performance on various older graphics HW - XAA solves this -- 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 : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
