I think this has been fixed in git master and the 1.5rc releases. Alex </blockquote></div> It's the current Fedora xserver package, so it's a little hard to say. :-) The rpm version string is 1.4.99, and the source file in the srpm is xorg-xserver-20080612.tar.bz2. It looks like that was generated by checking out commit #53a84d75c65f75c629c6610a2ec4093507cea3f7 from git://<a href="http://git.freedesktop.org/git/xorg/xserver">git.freedesktop.org/git/xorg/xserver</a>, assuming that my rpm-fu is strong enough to understand the setup. It appears, though, that this didn't come from the server-1.5-branch, since that's in the other arm of the script used to make the git snapshot. So it looks like I'll have to wait for a 1.5-based server to make this work. Out of curiousity, is there a way to look for the commit that fixed this? I could try turning it into a patch and rebuilding the rpm to see if it fixed the problem. Thanks, Don
