Bug Description
Binary package hint: kdebase-workspace
Kubuntu 9.04 fresh install, fully patched. PPA added to install KDE 4.3 RC2. System Settings/Display shows my two monitors correctly (DVI-1, DVI-0) and correctly identifies their available and preferred resolutions (although configures the larger with the resolution of the smaller).
xrandr reports:
Screen 0: minimum 320 x 200, current 1280 x 1024, maximum 1440 x 1440
DVI-1 connected 1280x1024+0+0 (normal left inverted right x axis y axis) 338mm x 270mm
1280x1024 60.0*+ 75.0 60.0*

However, selecting the Multiple Monitors section gets me:
"This module is only for configuring systems with a single desktop spread across multiple monitors. You do not appear to have this configuration."
Which is a lie. Although to be absolutely pedantic, it's true, I have one desktop repeated on two monitors but would really, really like to have "a single desktop spread across multiple monitors" - and had presumed that's what the Multiple Monitors tab should be helping me to achieve? If not, then how? If not, then maybe that message should include the hint about how to get to that state so that Multiple Monitors?

Note for those with a similar problem and to save some posting time for the technical elite:
I know of two ways to manually enable two monitors as there was in KDE4.2, namely writing your own xorg.conf (can post my sample if others are interested) or using xrandr to achieve the desired result on a per session basis (although I had to add:
Virtual 2720 1024
into the otherwise generic "Screen" section of my xorg.conf to get xrandr to allow me to use
xrandr --output DVI-0 --auto --output DVI-1 --right-of DVI-0
(you also have get the larger screen into the right resolution first by disabling the smaller (DVI-1) and setting the larger to its preferred resolution then reenabling the smaller). The size of the Virtual section is the maximum of your virtual desktop as determined by the xrandr output, in my case left plus right screens' widths and the height of the tallest screen.
However, I can't see me explaining any of these workarounds to my elderly mother...

Version: KDE 4.1.96 (4.2 rc1) (using Devel)
OS: Linux
Installed from: Compiled sources
I'm running Arch Linux with the current KDE 4.1.96 packages.
In the "Configure Display" window I have 3 entries:
First is "VGA" which is greyed out because nothing is connected to VGA
Second is LVDS, the notebook's built-in display
Third is TMDS-1, an external screen connected via DVI.
Only the VGA entry has buttons to set the position, which are of course disabled.
For the 2 connected displays I can only set the position by running xrandr on the commandline.
