Hello,
I have a machine with a head (currently) that I run both xfce 4 and KDE 5 on w/o issue. I'm trying to get VNC working so I can go headless.
I'm using tightVNC 1:1.3.9-9+deb10u1 running on Proxmox VE 6.3-3 (which is mostly Debian 10).
The remote machine is a Win 10 Pro running tightVNC as well.
VNC works fine with xfce 4.
VNC with KDE 5, I get a grey screen with a arrow cursor (as opposed to an X cursor).

Any assistance would be appriciated. I much prefer KDE do the vastly superior applications.

~/.vnc/xstartup looks like:

Code: Select all

#!/bin/bash
xrdb $HOME/.Xresources

# Allow copy & paste when ClientCutText is set to true on the client side
autocutsel -fork

# Uncomment below to run xfce over VNC
#startxfce4 &

# Uncomment below to run KDE Plasma over VNC
startkde &


Here is the log file from tightVNC:

I double checked that the file "xstartup" is executable. So that's not the issue.

It looks like KCrash is called a few times in the log file:

Code: Select all

KCrash: Attempting to start /usr/lib/x86_64-linux-gnu/libexec/drkonqi from kdeinit

I checked that the files exist in their expected locations.
Can anyone give me some pointers as to why KDE appears to be crashing?
