Kubuntu dual screens problem

[Guest]

Hello,

I tried to google for the problem but I was able to find all other kinds of problems but not mine.

The scenario is following: I have a laptop (with ati radeon) with external monitor connected via display port. I have my desktop on both screens. When I disconnect external monitor, my laptop screens gets corrupted as on the following picture:

Those bars move, it's not static. Even if I plug in my external monitor again, I get the desktop on both screens but laptop screen isn't corrected. It still displays garbage. I have to restart the laptop to fix the problem.

I tried to use xrandr (to disable laptop output and then enable it again), putting laptop to suspend and wake it up but without success.

Any pointers what could cause it? Refresh ratio is got wrong? How to fix it?

Best regards,
badyl

Problem solved - after switching from fglrx drivers to the opensource driver problem disappeared.

Thanks,
