Version: (using KDE 4.0.2)
Installed from: Ubuntu Packages
OS: Linux
I run a current Kubuntu system with a dual head NVidia card and the
proprietary NVidia drivers. For various reasons I have to run the dual
head as two X servers. My current X config runs fine with KDE3, when
running KDE4 however both heads desktops are drawn on top of one another
on only one of my displays, the other display is inaccessible.
Additionally the desktop config tool under KDE3 correctly identifies the
two displays but under KDE4 it sees only one the displays. I enquired
about this problem on the Kubuntu-kde4 IRC channel where another user
reported the same issue, but no known fix.

Remove your metamode entries and see if that helps.

Sorry for the slow reponse, it's a work machine and it's difficult to
get chance to fiddle with it that much!
I'm now using KDE 4.1, whatever Ubuntu feeds me from deb
http://ppa.launchpad.net/kubuntu-members-kde4/ubuntu hardy main
Removing meta-modes has made no difference :-(
However if I go away from the two X server approach to use TwinView (not
my preference) I do get both displays rendered correctly. I then get a
different bug where using the Display System Setting applet the primary
screen shuts down (probably out of range/res etc for that display) and
the sceondary screen is left, with little use (moving mouse pointer no
right click menu). I'm assuming I should file this as a separate bug but
I've also included the info here in case it's of any interest to solving
this issue?
Interestingly it appears to be picking the smaller display as the
primary and the larger display as secondary, the inverse of how it
appears under KDE3.

Marco: Yes (See also duplicate bug 166174). My setup is Kubuntu 8.10
with Kde 4.2 beta2 from the launchpad repos
(4.1.85-0ubuntu1~intrepid1~ppa1), proprietary amd fglrx driver (8.561)
and dual head setup. Under KDE4 the second screen stays blank. Amdcccle
(amd graphical config tool) can identify second screen (displays
identification number on second screen) and I can move the cursor over
but it will have a different shape (X) on the second screen. On first
screen panel is not visible (maybe because screen size is taken from 2nd
display which has 1600x1200 instead of 1st displays 1400x1050??). Good
old Windowmaker works perfectly fine with an otherwise unchanged setup.
Under Kubuntu 8.04 with KDE 3.5.10 and same fglrx version dual head
setup also works (although 3.5.10 has introduced another dual head Bug
170465).

Marco: this is about multihead (multiple X servers running at once, one

I also have the issue that Multihead is not supported by KDE. I have
briefly reported a bug on LP
(https://bugs.edge.launchpad.net/ubuntu/+source/nvidia-
common/+bug/329466) also. My setup is as follows: 1 Nvidia 9500 GT
graphics card, with 3 outputs - DVI, HDMI and VGA. I have 3 screens, 2x
22" (1680x1050) and 1x 26" (1920x1200). Now because separate x screens
are not supported, there is no way to make all of this hardware work
together nicely.
At the moment I can use twinview, with any combination of the screens,
and any combination of the outputs.
I am on Kubuntu Jaunty. (KDE 4.2.1)
