@Radomirs:
Please, before setting dual screen, disable desktop effects (compiz).
Compiz cannot work at resolution higher that 2048x2048 (yet) on i915/945 hardware, limitation of HW 2048x2048 max texture size.
Without Desktop effects your dual screen configuration should work. (it is then limited to 4096x4096 framebuffer size.)
With Desktop effects and resolution 1024+1024, you probably will experience this BUG.

@MJB-ESOFT:
The same as Radomirs.

@Andcor:
Please disable desktop effects. Then attach external display. Do what yo do to activate it.
Check combined screen resolution.
If it is 2040 width, then it is this BUG.
If it is larger, then the same as Radomir.
If lower, then different BUG.
