--- Comment #9 from boris64 bugs.xorg@boris64.net 2010-07-22 09:42:54 PDT --- Appendix: If i run 'xrandr --output DVI-1 --off' followed by 'xrandr --output DVI-1 --auto' the second monitor switches off and then on again (garbled screen).
Now if i run 'xrandr --output DVI-0 --auto' (happend accidentally first time), monitor one switches to off and the second monitor shows a correct piture again. Huh?! Running 'xrandr --output DVI-0 --auto' afterwards makes monitor one work and monitor two have a garbled picture again.
Will now try that cold boot thing.
