Created attachment 17535 [details] xdpyinfo output Hi, I've updated my ati driver from 6.8.0 to 6.9.0 and my xrandr configuration stoped creating one large desktop so I ended now up with 2 monitors showing the same content (mirroring).... The xrandr command I'm using since the switch from xinerama to xrandr was made is: xrandr --output VGA-0 --right-of DVI-0 please find attached my xorg.conf, Xorg.0.log and the output of xdpyinfo

The driver supports cloning now so you can have multiple outputs driven by the same crtc. You'll need to specify the crtc if you want to drive the outputs independently. Ideally the xrandr utility should do this automatically for multi-head, but that needs to be fixed in xrandr not the driver. xrandr --output DVI-0 --mode 1280x1024 --crtc 1 xrandr --output VGA-0 --right-of DVI-0
funny - when I switched from xinerama to xrandr the previous left display became my right display and vice versa. So I had to adjust my window manager config - but now it is back to xinerama. So I've to reconfigure it again but - problem fixed I'd say.
oups... no - it is not OK - now I've only one Screen - but I want to have two screens - think about the background image for example - now it is streched about both screens....
ok - it looks like the new xrandr command should have been put into .xinitrc so the displays are configured before my window manager is started so it gets its configuration correctly - changing the xrandr setup this way while it's running didn't worked... now having it in .xinitrc before the WM starts it's ok. changing it to FIXED
FWIW, you can setup dualhead statically via your xorg.conf even with xrandr 1.2: http://wiki.debian.org/XStrikeForce/HowToRandR12
