Hi Robert, Robert Noland wrote: > It still might be useful... Option "BusType" "PCI" With "radeon" driver: When xorg is started, my 2nd monitor keeps being black. The 1st one is working. It looks like the hardware acceleration is not being used as moving windows on the remaining monitor is really slow again. xrandr lists the 2nd monitor. Switching to console and back does work - but the 2nd monitor remains black (no signal). On Xorg Startup I get: info: [drm] Setting GART location based on new memory map error: [drm:pid728:r600_do_init_cp] *ERROR* Need gart offset from userspace in Xorg.log: (II) RADEON(0): AGP card detected (**) RADEON(0): Forced into PCI mode pro: switching works contra: no hardwareaccel., no dualhead With "radeonhd" driver: BusType seems to have no impact. The same behaviour like without. Switching to console and back makes Xorg hang. in Xorg.log (II) RADEONHD(0): AGP Card Detected Nothing about PCI mode. pro: dualhead, hardwareaccel, contra: no switching Without the "busstype" Option, the radeon driver seems to be a bit more performant for me because switching between my virtual desktops makes the system hang for about 1-2 sec. with the radeonhd driver sometimes... I've uploaded both Xorg.log files here: http://files.pofo.de/Xorg.0.log.radeon http://files.pofo.de/Xorg.0.log.radeonhd -- Oliver Lehmann http://www.pofo.de/ http://wishlist.ans-netz.de/
