X2Go is a remote desktop solution which allows users to open a graphical user interface on a remote server. It is currently supported on Cedar.

2. Click on the icon that represents a file with a little star. This will prompt the screen "X2Go new session"
3. Fill in the required information as displayed on the image. Make sure that you select the "ICEWM" desktop from the "Session drop-down menu, as this is the only desktop supported on Cedar.

4. Once the session is created, click on it (it will appear int he main window, enter your username and password, and wait. It may take a few minutes until the desktop appears, but once it appeared, it should be reasonably fast.
