Kubuntu 9.04 - Can't drag application from one screen to another in multi monitor setup

2

I have a new install of Kubuntu 9.04. I installed the ati drivers.

fglrxinfo
display: :0.0  screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: ATI FirePro V3750 (FireGL)
OpenGL version string: 2.1.8794 FireGL

When dragging a window from one monitor to the second monitor it stops when the mouse hits the edge of the screen.

Any ideas?

What settings are you using? In particular, is your second monitor set to "TwinView" or "Separate X Display"? How are you configuring the two monitors? – CarlF – 2009-10-05T17:14:56.763

the reason you can't drag windows from one 'head' onto another 'head' is (as CarlF correctly commented) that your setup is in "separate x display" mode and not in "xinerama mode" (aka "twinview in nvidia-land or "bigdesktop").

such a "separate x display" setup means, that each head can possibly run a completely different configuration regarding visual depth, size, framerate etc. thus, a window created on one head (the term is actually "screen") can not be savely moved onto the other head because the "pixels do not match".

checkout http://ubuntuforums.org/showthread.php?t=221174 and configure your xserver correctly, then your problems will vanish .)

I finally got it working with the help of this blog post http://sensiblerationalization.blogspot.com/2009/06/dual-monitor-setup-with-fedora-10-and.html
