I don't either have out-of-the-box desktop effects with my Radeon X800 in Ubuntu (window border disappear when enabling desktop effects, and no effects actually appear), but I'm quite certain it's a not a problem in xserver-xorg-video-ati, but in Ubuntu's compiz / desktop-effects / something.
I'm writing this from a Fedora 7 test 2 live CD I just burned, and here I do have everything working fluently by just enabling System / Preferences / Desktop Effects, despite the fact the xserver-xorg-video- ati is the same version as in feisty (6.6.3), as well as same X.org (7.2), Mesa (6.5.2) etc. Compiz is "0.3.6-2.fc7". I reassign this bug to compiz... ** Changed in: xserver-xorg-video-ati (Ubuntu) Sourcepackagename: xserver-xorg-video-ati => compiz Status: Unconfirmed => Confirmed -- [feisty] desktop effects problem (ATI) https://launchpad.net/bugs/90184 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
