Created attachment 15940 [details] Working Xorg log I have a machine with two radeon cards (rv370), each dual head. This setup works correctly using Xinerama with the xf86-video-ati-6.6.3 driver. If I try to use a later driver (I have tried 6.8.0 and git repository from 2008-03-21), it fails with the following symptoms: 1. segfault if xinerama enabled in server flags (so we disable it) 2. screen 0 works as expected 3. screen 1 is drawn but mouse cursor is corrupt -- it appears as a white box with some seemingly random black pixels 3. screen 2 seems to work (mouse is drawn) 4. X server crashes if mouse is moved onto screen 3. I will attach log files with the 6.6.3 driver and the git driver. (For reference I originally reported this as http://bugs.gentoo.org/show_bug.cgi?id=214136 ).

I can confirm this with my setup which is very similar: * two rv370 cards with each DVI+VGA * two monitors attached to the two DVI ports I does not run on Fedora 9 Preview based upon * xorg-x11-drv-ati-6.8.0-10.fc9.i386 * xorg-x11-server-Xorg-1.4.99.901-22.20080415.fc9.i386) Problems are similar than the post above. The same hardware runs without any problems on Fedora 6 based upon * xorg-x11-drv-ati-6.6.3-1.fc6 * xorg-x11-server-Xorg-1.1.1-47.10.fc6 I am able to recompile the ati driver from TAR or SVN to offer my help. Please feel free to contact me for any tests. Also I can attach log files or debug output if requested.
I tried running a git-bisect to narrow down the problem, but due to the wide variety of different behaviour I experienced I'm not sure the process was successful. Anyway, with "good" == "working perfectly" and "bad" == "anything wrong", git-bisect gives commit e8d77b7c36fa791a2350a6f4b15728b15d8f3de0 as the first non-working commit. Of course this has different behaviour (all screens blank but no crashing) to what I'm experiencing at 6.8.0, so it's possible this introduced a bug which was fixed later and my issue is something separate.
can you try with latesst ati git tree please? for the Fedora reported the F9 packages are at http://koji.fedoraproject.org/packages/xorg-x11-drv-ati/6.8.0/13.fc9/ It should at least fix the mouse in screen 1, but may fix other bits. please attach the xorg.conf also you are using.
I can confirm that the driver works correctly with the latest git, commit b416e97a1f16ef700ba1aaca317dee82b7a3cf64 . xorg.conf to be attached shortly.
Created attachment 17149 [details] xorg.conf xorg.conf used with latest git driver. Note "xinerama" serverflag has been commented out; with 6.6.3, this is uncommented, but the file is otherwise unchanged.
Definitely works with xf86-video-ati-6.9.0, bug should be closed.
