KDE4 incompatible with remote X sessions?

[thegoonden]

I use a laptop as a glorified remote control for my main desktop/media PC.
I usually have a few ssh sessions open in Konsole and that's fine for most things.
Sometimes I would need a GUI program displayed back to the laptop from the desktop.


Until KDE4 came along, that was easy.....

export DISPLAY=laptop:0
appname


But now I get this..........

steve@hal9000 ~ $ export DISPLAY=laptop:0
steve@hal9000 ~ $ dolphin
<unknown program name>(28267)/: KUniqueApplication: Cannot find the D-Bus session server: "dbus-launch failed to autolaunch D-Bus session: Autolaunch error: X11 initialization failed.
"

<unknown program name>(28266)/: KUniqueApplication: Pipe closed unexpectedly.


I have run xhost + on the laptop.

I assume I need to get the two machines DBuses talking?


Any ideas?
