Created attachment 24530 [details] [review] multi-seat Xorg configuration file I have two radeonhd cards: primary (integrated rs780) and secondary (rv710). I can get both cards working in the same time with the single Xserver configuration, but when i use multi-seat configuration (each card have their own Xserver) the systems becomes very unstable. Also i got an artifacts on the secondary monitor.

Does: Option "VGAAccess" "FALSE" in your device sections help?

(In reply to comment #7) > > Does: > > Option "VGAAccess" "FALSE" > > in your device sections help? > > is it usefull with PCI/E cards? > Yes. It doesn't matter what type of bus the card has. That option prevents the driver from doing legacy vga io. See the radeon man page for more info.
No, it does not help. The integrated (primary) card initialize properly, and the second card initialize with problem (every element on a screen was doubled, e.g. two mouse pointers shifted from each other on a distance about 5 mm, every letter on a screen has it's copy with the same distance and so on) the restart of 1-st Xserver via Ctrl-Alt-backspace was ok but the restart of 2-nd Xserver finished with total freeze of the operating system. I have no such issues, when i replace the second radeon with nvidia (driver nv) and use radeonhd driver for integrated radeon videocard.
