Please uninstall the fgrlx driver including the aticonfig tool. If you
use the RPMs from the openSUSE buildservice you can just run 'sax2
-r'. This will generate a single head configuration. To this single
configuration (/etc/X11/xorg.conf) add

  Virtual 2960 1050

to the appropriate 'SubSection "Display"' in 'Section "Screen"',
probably the one with colordepth 24. Then you can use xrandr later for
dynamically configure your desktop.

  xrandr --output <output1> --left-of <output2>

Check the output names by running xrandr without any options first. This
is also described in '9.5. How do I set up multiple monitors?' on

  http://wiki.x.org/wiki/radeonhd
