Using:
KDE4.2.0-r3 Gentoo 2008.0 ~amd64 NVIDIA Geforce 285 & 8500 I am running a dual X server setup across two different video cards (one onboard one pci-e). Both NVIDIA's. Using Gentoo 2008.0 in the ~amd64 branch, everything is current up to date, and it is a fresh build. I used my xorg.conf from my previous build which worked flawlessly (with kde3.x a while ago). Now when I run KDE4 I get my main monitor which shows the background, however the bar and everything is below/out of screen of the monitor, and my mouse wont let me travel down that far. On the second screen, all I get is a black screen, with the X mouse cursor I can move around (like xkill), and can do absolutely nothing on that screen.. This issue does not present itself across Gnome or XFCE, so it's definitely a KDE4 issue.. If anyone has any ideas or insight that would be appreciated, thanks!

KDE 4 does not support Multihead X ( or Multiscreen X ).
Only TwinView, MergedFB, etc. are supported in KDE 4.

Ouch! Thanks for the fast reply! That hurts though.. Is there any development for it / any plans to support it in the future?
Thanks again. Does Xinerama work on it? Isn't that essentially dual head? I'm reading mixed reports that it works on KDE4.. Any suggestions there?

Yes, Xinerama is supported. At this time Multi Head will be supported when a developer steps up and implements the required functionality.

TwinView, Big Desktop and MergedFB are all accelerated Xinerama implementations and work fine in KDE 4, use them over the built-in Xinerama if possible. "Dualhead" and "multihead" commonly refer to a single X server that has multiple X "screens" attached to it (Unlike Xinerama which has a single "screen" spanning multiple physical monitors).

Thanks! Yeah I guess terminology was confusing for me. Last time I tried to use TwinView/Xinerama several years ago there were still issues maximizing apps on one screen, and weird things like that. Which is why I went to two screens/xservers. I got Xinerama working last night across both video cards and monitors on KDE4 and it seems to be working good for right now, haven't noticed any of the weird bugs as before. I appreciate the help!
