As long as the SSH port has been opened, you shouldn’t have to configure anything else (e.g. Remmina is convenient because it handles the SSH tunnel.

Enter the SSH settings under the SSH Tunnel tab. COMPUTERNAME.local:1, :1 corresponds to the display number above). Enter the VNC connection settings under the basic tab (e.g. If using Ubuntu 20.04 as the client machine, Remmina (a VNC client) is installed by default. Sudo systemctl enable systemctl start systemctl status Connect Using Remmina VNC Client sudo mkdir /etc/vncĮxecStart=/usr/bin/vncserver -fg -depth 24 -geometry 1920x1200 -localhost no :%i This will create the typical Ubuntu desktop. & xrdb $HOME/.Xresources chmod 755 xstartupĬreate /etc/vnc/xstartup, edit the file, make executable. The fix comes from this post.Ĭreate ~/.vnc/xstartup, edit the file, make executable cd ~/.vnc Instructions found in other tutorials might work if you manually start the VNC server, but you will get a black screen if starting it as a service with GNOME (although it works with XFCE4). We want to run the VNC server as a system service (starts at boot), using GNOME (i.e. Vncserver -kill :1 Configure the VNC Server Ubuntu 20.04 Remote Desktop Access with VNC The chapter entitled Ubuntu Remote Desktop Access with Vino explored remote access to the Ubuntu GNOME desktop using the Vino server, an approach that is intended solely for situations where the remote system is already running a GNOME desktop session. Test the installation by starting and then killing the server. TigerVNC supports virtual displays, is an active successor to TIghtVNC, and is easy to install from the Ubuntu repositories sudo apt install tigervnc-standalone-server Others can support virtual (remote) displays that are truly headless. controlling the visible logged-in desktop). Some VNC servers only support local VNC sessions (i.e. It was easy to set up a local VNC session, but going headless without a dummy adapter AND with the GNOME desktop was a challenge. no monitor plugged in) for Ubuntu 20.04 using GNOME was harder than anticipated. Automatically switches configuration on launch to fully support CPU only or GPU instances.Creating a headless virtual VNC session (i.e.Accelerated 3D applications with full OpenGL support on GPU backed instances.Remote desktop access with VNC through web browser.
