My current setup is:
[alex@fatty gnome-control-center]$ xrandr
Screen 0: minimum 320 x 200, current 2944 x 1280, maximum 8192 x 8192
HDMI-0 connected 1920x1080+1024+200 (normal left inverted right x axis y axis) 600mm x 340mm
DVI-0 connected 1024x1280+0+0 left (normal left inverted right x axis y axis) 376mm x 310mm
I.e. a rotated 90 degree on the left, aligned at the bottom.
The pointer containment seems to work for the right monitors top, but while at the topmost row the cursor disappears.
Additionally i have a pointer barrier at 1024,200 - 1024,248. It seems to stop the cursor going from the right monitor to the left, *except* when the cursor is at the top. Then it can pass.
