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
chkconfig nvidia off
(so your config doesn't get mangled each reboot)
(generates fresh xorg.conf, choose nvidia driver and single-head)
(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.
