Xorg logfile
Hi,
I'm trying to fire up my triple head setup with a Radeon 5750, but in the end
Xorg segfaults.
First of all the setup:
Fedora Rawhide x86_64
xorg-x11-server-Xorg-1.8.0-6.fc14.x86_64
xorg-x11-drv-ati-6.13.0-1.20100406git819b40153.fc14.x86_64 (also tried current
git)
kernel-2.6.34-0.28.rc3.git3.fc14.x86_64
3x Samsung Syncmaster 2343bw with a strange 2048x1152 resolution
Two of the screens are attached via dvi-d, the other one is attached via
hdmi-to-dvi

So far using only two of three screens aka dual head connected works fine. No
problems so far. Just a lot of error messages during boot until Xorg fires up.
HDMI/DVI mixed setup works out of the box. See log.dh for complete dmesg
output.
Error message repeated several times:
radeon 0000:02:00.0: object_init failed for (9437184, 0x00000002)
[drm:radeon_gem_object_create] *ERROR* Failed to allocate GEM object (9437184,
2, 4096, -22)
[drm:radeon_gart_bind] *ERROR* trying to bind memory to unitialized GART !
[drm:radeon_ttm_backend_bind] *ERROR* failed to bind 2304 pages at 0x00000000
[TTM] Couldn't bind backend.
When I boot Linux with three screens connected, the colors of one monitor are
wrong. Black is dark green, white is light green which is difficult to read.
Other colors are also some sort of green. But at least the console is shown and
in sync with the other screens. So KMS is able to fire up all screens.
Again there are lots of the above error messages. See log.th
Xorg segfaults. GDB output and Xorg.log are attached, but I'm not sure if the
xorg.log is consistent, beside the missing debugging symbols, to the gdb
output.
Program received signal SIGSEGV, Segmentation fault.

Fatal server error:
Caught signal 11 (Segmentation fault). Server aborting
When I attach the third screen to a running xorg dual head session it is
recognized by xrandr. But when I activate the third screen via xrandr then xorg
segfaults again. After this there's no greenish color anymore on the console.
Program received signal SIGSEGV, Segmentation fault.
