Description Vasilis.Vlachoudis 2011-05-12 10:47:12 UTC

Version:           unspecified (using KDE 4.6.2) 
OS:                Linux

Primary screen: 1920x1200
Second screen: 1680x1050 (rotate by 90deg on left)
Video card: Nvidia with the nvidia driver
I have disabled Twinview and xinerama since they cannot handle two screens with different rotations.
Therefore I am running as two separate x-screens.

When KDE starts it opens two desktops on both screens (:0.0 and :0.1):
Problems:
1. kwin is not started automatically for the second screen :0.1. Easy to fix, I am starting manually with kwin -display :0.1
2. the first screen shows a strange resolution of 1920x1168 however I am not able to place a window after Y:1000px. the bottom 200px are somehow lost.
3. the second screen behaves like if it has a resolution of 1920x1200 (the one of the primary display) instead of 1050x1680 (which by the way is correctly reported in the Settings program) thus when I open any new window is lost in the non-visible area.

Up to now the only solution I have was to use kwin for the primary display and another window manager like openbox, twm for the secondary display, then everything works ok.



Reproducible: Didn't try

Additionally: I just realized now that also the global shortcuts are getting confused. When I enable the dual screen the Meta-XXX shortcuts do not work any more

there will be multi-head improvements in 4.7

While  you are waiting for those improvements in 4.7, please check out a workaround idea here:

Comment 4 Martin Flöser 2013-01-20 19:03:09 UTC

I assume the issues are fixed by now due to the improvements in 4.7. If one of the issues is still present please report a new bug and please report one bug per issue.
