Are you asking about dual head (ie 2 displays and keyboards) or 2
displays for one user ?

I am using dual displays and it works fine.

Is anyone using KDE 4 with a dual-head setup?  From my brief testing, it
seems almost unusable.  In particular, the second screen ends up with a
solid gray background that doesn't even respond to mouse clicks.

Is this one of the many pieces of basic functionality that has been
sacrificed for the KDE developers' "grand vision"?

Indeed this is somehow broken in 4.1 (but it's better in 4.0 where it was
completely unusable). It will be better in 4.2, work is ongoing on fixing this
mess.

The rpmfusion/livna Nvidia driver has a nasty bug that impacts any app or
library that tries to load the xrandr extension (which most of the KDE 4 libs
do) when you're using Xinerama.  I was able to make it mostly behave with the
following technique:

chkconfig nvidia off
(so your config doesn't get mangled each reboot)

system-config-display --reconfig
(generates fresh xorg.conf, choose nvidia driver and single-head)

nvidia-settings
(set up dual-head, uncheck "merge with existing" when saving xorg.conf)

It'll still cause a segfault if you try to load anything that touches xrandr
config (like krandr, or the Display control panel), and I get occasional
weirdness, but it generally works.  I fully intend to complain to the proper
authorities once I figure out what's going on, but I'm pretty sure that KDE is
just a victim of Nvidia's xrandr badness.
