I see "(WW) RADEON(0): R500 support is under development. Please report any issues to <a href="mailto:xorg-driver-ati@lists.x.org" target="_blank">xorg-driver-ati@lists.x.org</a>" in my Xorg.log. I have issues. This is e-mail is my report. I have tested the -ati/-radeon driver with my R580 under both fresh&upgraded Ubuntu intrepid and jaunty installs. For both releases my issues are essentially the same and can be read about here: Launchpad bug <a href="https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/342899" target="_blank">#342899</a> Here's a quick summary: DRI hoses everything (massive corruption) Neither EXA nor XAA are able to redraw/update correctly, see attached image of the result of dragging a window. Scrolling in a window is out of the question. The driver "works" with Option "NoAccel" "true" Any advice? Cheers, ~l3iggs
