mg@pitonas:~ $ xrandr
 SZ:    Pixels          Physical       Refresh
 *0   2304 x 1024   ( 585mm x 260mm )  *-21130
  1   2048 x 768    ( 585mm x 260mm )   18969
  2   1280 x 1024   ( 585mm x 260mm )   20398
  3   1024 x 768    ( 585mm x 260mm )   -25873
  4    800 x 600    ( 585mm x 260mm )   -25882
  5    640 x 480    ( 585mm x 260mm )   -25880

The first two are dual-headed modes, all the rest are clone modes.

I use xrandr -s 0 to switch to the largest dual-head mode, and xrandr -s
1024x768 to switch to clone mode.

I haven't tried it for a looong time.  I have noticed in freedesktop's
bugzilla (I think) that Radeon Xinerama (not MergedFB) seems to be
broken in X.org 7.0.

To err is human, but to really foul things up requires a computer.
