This seems to be related (I will check asap)
This is not a KDE4 related. I experience this also with xmonad, openbox, lxde...
@Comio I also have this problems as on that link you pasted: https://bugzilla.kernel.org/show_bug.cgi?id=26552 I've also uploaded a video http://www.youtube.com/watch?v=rjhAknBoJDE
Has anyone found a solution yet to one or another bug? (if they are even related) or do we have to wait for next kernel release?
Try to use the old pll (new_pll=0 option). My problem is different: when the software probes the second screen (like xrandr -q) the external monitor shows for a second a black screen. The solution seems to disable the krandr periodical probe... but I will test in this afternoon at home.
best regards.
