Hi all, I run KDE 4.1.2 in Kubuntu 8.10. I use the proprietary NVidia display drivers in a TwinView configuration (i.e. two monitors side-by-side, treated as one X display). When I try and put background images on both my "screens" with KDE, it works, but I get the following:

As you can see, there is gray-and-white squares between the two images (which appears at the far left edge of my right screen. My left screen is obviously my primary screen which always appears perfectly) and there's a weird double-dashboard icon in the top middle. There is nothing technically wrong - I can put windows over the top of that empty space, it just doesn't get painted properly with the second background image. Doesn't matter what resolution the image is or what positioning I use, it just never gets filled.

My screen config in xorg.conf is:

Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"
DefaultDepth 24
Option "NoLogo" "True"
Option "TwinView" "1"
Option "UseEdidDpi" "False"
Option "DPI" "96 x 96"
Option "DynamicTwinView" "1"
Option "TwinViewOrientation" "RightOf"
Option "metamodes" "DFP-0: 1920x1200, DFP-1: 1280x1024 @ 1280x1200"
EndSection

Does anybody have any ideas about why this may not be working correctly?

Thanks

Brett.

The strange imagery you see is an Unpainted area of a QGraphicsWidget, the underlying technology of Plasma's graphics. Could you please re-test this on KDE 4.2, as many multi screen bugs have been fixed in this release?

Thanks for the info! I'm a bit nervous about trying the update at the moment (easiest way to do it for me is just to update from Kubuntu repositories) as if anything goes wrong, I can't afford to waste time trying to get it working again - this is my work machine. I might just wait until the stables are out then see if it fixes it. Not a big deal if the grey stripe stays there a touch longer! Thanks!

Ok I had some spare time so took the dive into 4.2 Beta 2. Now I receive the following display:

There is still the gap between the two backgrounds (which I presume means I need to log a bug report?). But you'll notice something even weirder. My main monitor (on the left) has the taskbar all the way across the bottom. Where the panel finishes, my second physical monitor starts. But KDE has somehow not figured things out correctly and has put my main desktop (including icons) on the right-hand side of it (so it actually covers my full right monitor and about a third of my main left monitor), and the other side on the left, taking up the remaining two thirds of the screen. Everything works as I expect it to - windows drag from left to right, they start at the top left corner of my main screen, etc, its just the layout of the desktop and wallpapers is screwed!

Any ideas?

Thanks

Brett.
