miscellaneous vnc problems

I had miscellaneous vnc problems with the server running Suse. Unable to use smb4k to mount windows shares and rdesktop not opening using the VNC connection. Error mesg was

rdesktop server-ip
Autoselected keyboard map en-us
X Error of failed request: BadMatch (invalid parameter attributes)
 Major opcode of failed request: 1 (X_CreateWindow)

Thought it might have something to do with the window manager - twm and not KDE. According to this page, I could change it by editing ~/.vnc/xstartup to

#!/bin/sh
/usr/bin/startkde

But that did not help. Then thought it might be the colour depth. Changed the colour depth to 16 as

vncserver -geometry 800x600 -depth 16 :68

That did the trick.

Next, vncserver was getting into a loop or something when I try to run it from a putty session, but not when I run it from a terminal in Linux! This turned out to be some sort of vnc allergy to ssh tunnels - when I used putty without any tunnels, vncserver created desktops without complaints.

Then P solved the issue with smb4k:
In settings -> configure Smb4k -> super user
checked the boxes which say "Use super user privileges to mount and unmount shares", and also for 'force unmounting', gave the su pw when asked. Now it mounts.
