xorg.seat1.conf
Trying to port a long functioning fglrx multiseat setup to use the radeon
driver as the X.org 1.13.0 in Ubuntu 12.10 is incompatible with the old fglrx
and the new fglrx is incompatible with my R600 (4350).
What happens is both cards/screens successfully change modes for the graphical
console. However, when KDM comes up, only seat2 (4350) enters X. seat1 (5770)
fails with a KMS error.
[ 60.389] (EE) RADEON(0): [drm] failed to set drm interface version.
[ 60.389] (EE) RADEON(0): Kernel modesetting setup failed
If I exit X and restart (sans xorg conf), the 5770 works fine (of course the
second server is not started).
I am launching the two X servers via KDM thusly (note shared vts):
ServerArgsLocal=-config xorg.seat1.conf -nolisten tcp -isolateDevice PCI:2:0:0
ServerArgsLocal=-config xorg.seat2.conf -nolisten tcp -isolateDevice PCI:1:0:0
-sharevts -novtswitch
I have udev rules tagging the input devices and those xorg.seat*.conf files
(attached) use MatchTag to work with that. Their Device sections look like:
Section "Device"
Identifier "Seat1"
Driver "radeon"
BusID "PCI:2:0:0"
Option "Int10" "off"
EndSection</pre>
