Graphical (X11) Applications
Graphical applications can be run by tunnelling X11 over an ssh connection. However, this does not work particularly well on low-bandwidth or high latency connections because X11 creates many round-trips which adds significantly to the rendering delay. A superior approach is the NX protocol developed by nomachine.com . It is available on the trcomp nodes via X2Go. It can be used for a single-application or a full remote-desktop connection. Connections use the built-in ssh client of the X2Go client. ssh-key authentication can be used making single-click passwordless connections possible.
Download and install the X2Go client for your platform
Configuring X2Go for connecting to a trcomp node
Create a session for the trcomp node that you want to use.
In the Media tab of session preferences, disable sound-support.
Remote-Desktop style connections
Session Type: XFCE
Over low bandwidth connections, XFCE is the preferred desktop-manager because it is simple and lightweight. Neither GNOME nor KDE are installed on the trcomp nodes.
Single-Application
Session Type: single-application
You can use this to open a single terminal from which you can launch other windows. Choose application "Terminal".
