Bug Description

This has worked with kde3 but not kde4
I want to use multiple vnc sessions
vncserver :1
vncserver :2
vncserver :3 etc...
+ my main kde4 X session that is not tied to any vnc

in xstartup, I have
startkde &
In Intrepid release twith kde4 his is not working
This used to work in Gutsy with kde3

When I try to manually start... I get the following.

userid@kubuntu$ startkde
startkde: Starting up...
kdeinit4: preparing to launch /usr/lib/kde4/libexec/klauncher
klauncher(10596) kdemain: Waiting for already running klauncher to exit.
klauncher(10596) kdemain: Waiting for already running klauncher to exit.
klauncher(10596) kdemain: Another instance of klauncher is already running!
kdeinit4: Communication error with launcher. Exiting!
kdeinit4_wrapper: Warning: connect(/home/userid/.kde/socket-kubu/kdeinit4__2) failed: : Connection refused
Could not register with D-BUS. Aborting.
startkde: Shutting down...
kdeinit4_wrapper: Warning: connect(/home/userid/.kde/socket-kubu/kdeinit4__2) failed: : Connection refused

I expect multiple instances of kde4 to co-exist for the same user in different vnc's. But kde4 refuses to co-operate.

Messed-up vnc4server kde 4.2 screen Edit (441.0 KiB, image/png)

Similar problem, Kubuntu 8.10, 32-bit. If I am logged in at the console, I kde4 will not allow another kde login session to start via vncserver. The work-around: log off the console if I need to use vnc.

Also, the screen quality is very poor with vnc sessions. Lots of hash, mouse turds, and messed up windows. See attached screen grab.

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue that you reported is one that should be reproducible with the live environment of the Desktop CD of the newest release - Karmic Koala. It would help us greatly if you could test with it so we can work on getting it fixed in the next release of Ubuntu. Thanks again and we appreciate your help.
