Comment 75 for bug 383345

@milos
your problem is unrelated.
i8xx HW cannot display framebuffer larger then 2048x2048.
It's a hardware limitation, not a system BUG.

@Radomirs
Please, at which combined resolution you get the black screen?

@Andcor
Please, what is your hardware?
Ubuntu does not automatically change resolutions after attach of external display.
Your BUG is unrelated to this one, in this BUG system does not crash.

@MJB-ESOFT
Please write you hardware.
Compiz cannot work at resolution higher that 2048x2048 (yet) on i915/945 hardware.
