Multiseat with VGAArbiter on 2 Radeon cards

[Steffen Schaumburg]

Hi,
thanks both of you for your replies - I'm going to try the KMS method
first. Now the problem is I can't turn off Arbiter in the kernel, make
menuconfig can find it with the search, but the option isn't in the
menu. Is there a boot option to force off arbiter (or, alternatively, to
force on KMS which would turn off arbiter by necessity?)? I checked the
docs at
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob_plain;f=Documentation/vgaarbiter.txt;hb=HEAD 
but can't see anything. Or should I just manually edit the .config file
- I'm inclined to trust menuconfig to not be displaying the option for a
reason, or am I giving it too much credit? Any pointers would be
appreciated.

Thanks, Steffen
