I figured out my issue with getting software rasterization -- it was the permissions on the device. Based on this bug report here:
http://bugs.freedesktop.org/show_bug.cgi?id=19492 I tried both "glxinfo" and "sudo glxinfo" and noted that in the former case I got software rasterization, while in the latter case I was getting "Mesa DRI Radeon..." As recommended in that bug report I set the permissions on /dev/dri/card0 to 0666 and am now getting Mesa DRI when I'm not the root user as well. Now EXA acceleration seems to be working quite well.

Interestingly, the permissions on the dri device node apparently still do have some relevance; at least they made a big difference in my case. Is there perhaps a bug lurking here? ** Bug watch added: freedesktop.org Bugzilla #19492 https://bugs.freedesktop.org/show_bug.cgi?id=19492 -- 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
