Installed in Docker Container UBUNTU rubensa/ubuntu-tini-x11 (latest) on QNAP NAS. I have defined ENTRYPOINT as
Code:
/sbin/tini -- /docker-entrypoint.sh
The contents of the docker-entrypoint.sh file:
Code:
#!/bin/sh
/etc/init.d/ssh start
/etc/init.d/cron start
/bin/date > /dev/shm/date
exec "$@"
The container is running and the command sequence defined in docker-entrypoint.sh executes correctly.
VNC server also starts with the following command sequence (from root):
Code:
rm -rf /tmp/.X*
rm -f /root/.vnc/*.log
rm -f /root/.vnc/*.pid
Xtightvnc :1 -depth 24 -geometry 1280x720 &
export DISPLAY=:1
Result:

However, when you try to run xface using commands (from root):
Code:
export DISPLAY=":1"
startxfce4 &
it ends up with a sequence of errors:
Code:

The first error message states that DISPLAY:1 is already taken. The rest of the errors are - as I understand it - a consequence of the former.
Can anyone help me and write what I am doing wrong?
