Hi Jeff,

Thanks for your response. However that doesn’t help too much. I know where to find a typical
log file, VNC logs are missing in /var/log. That’s the reason I post question for help.

Could you maybe try the provided only three reproduce steps yourself to see what is going

Sounds like you setup an Ubuntu container to run the VNC server in. So, in Linux the log files
typically go in the directory /var/log. You could look there. Try this to look for files with
vnc entries: grep vnc /var/log/* -R | less

You could also try tailing the messages log file in Ubuntu while you try to connect to the
vnc server: tail -f /var/log/messages.log

It might help to see what the vnc server is logging when you try to connect with the client.

Hi Jeffrey,

Could you maybe tell where is the location of VNC log files and what exactly you want for

Here is all I get from `docker log` command:

USER_ID: 1000, GROUP_ID: 0
nss_wrapper location: /usr/lib/

------------------ update chromium-browser.init ------------------

... set window size 1280 x 1024 as chrome window size!

------------------ change VNC password  ------------------

------------------ start noVNC  ----------------------------

------------------ start VNC server ------------------------
remove old vnc locks to be a reattachable container
start vncserver with param: VNC_COL_DEPTH=24, VNC_RESOLUTION=1280x1024
start window manager

------------------ VNC environment started ------------------

VNCSERVER started on DISPLAY= :1
        => connect via VNC viewer with

Hi Changkun,

Could you attach the log from the VNC server?
