The system is simple: Ubuntu 20.04 with the default desktop, which seems to be GNOME based - not what I would have chosen, but then this isn't for my use. I have been through more helpful web-pages than I care to list, but the latest, slightly successful one was TigerVNC (on Arch Linux), the section Running Xvnc with XDMCP for on demand sessions. The user should be asked for username and password.This is what I want to achieve, and as I understand it, TigerVNC should be able to handle it: This is worth another question.I am trying to setup TigerVNC - or indeed any VNC server - on Ubuntu 20.04, and I am beginning to get frustrated, because none of the instructions I can find actually work, although I have got it to work on CentOS. I found no way of releasing my remote xRDP session and start using the console. The few times I tried, the console got laggy, and finally it hung.Whatever I do in my client, it belongs to the client's session.This works well, but it has a couple of undesired features: I am at the console only once in about a month or two. I guess this means all the rest is mostly OK, even if not 100%. When I click on the password field, the pointer changes to a cursor, but nothing happens when I type. The problem is that at the login screen I cannot type my password. I entered the password I setup in step 2 above. Launched TigerVNC client in Win10, connecting to localhost:59000.Verified the service was inactive with sudo systemctl status Established an ssh tunnel to port 5902 (as per output above) with ssh -L 59000:localhost:5902 -C -N -l user1.Use xtigervncviewer -SecurityTypes VncAuth,TLSVnc -passwd /home/user1/.vnc/passwd myserver:2 to connect to the VNC server. New Xtigervnc server 'myserver:2 (user1)' on port 5902 for display :2. Killed service with vncserver -kill myserver:2.SELinuxContext=system_u:system_r:vnc_session_t:s0 Started service with sudo systemctl start Added symlink with sudo systemctl enable This created symlink -> Even if I later don't use the service, I note the linked file has a different contents from what is typically quoted:ĮxecStart=/usr/libexec/tigervncsession-start %i.Added user with sudo nano /etc/tigervnc/ers, adding :2=user1.Changed permissions with chmod +x ~/.vnc/xstartup.

Created/edited with nano ~/.vnc/xstartup, with the following contents (using gnome right away).

Killed the vnc server with vncserver -kill myserver:2.

Executed vncserver, and entered the password.

Installed (with apt-offline, since the server is behind a proxy) tigervnc-standalone-server, tigervnc-common, tigervnc-tools.

I did all the setup remotely, in a terminal connected via ssh. I mean to connect from Win10 to a remote server with Ubuntu 22.04LTS and Gnome desktop, via VNC.
