Download x2go client from here: https://wiki.x2go.org/doku.php/doc:installation:start
Once downloaded and installed you can connect to the node l002.incline.uccs.edu by using these settings:
Use your UCCS login without the @uccs.edu component.
You must pass in an ssh key, you can do so by clicking on the blue folder and selecting the filepath on your system.
You must use XFCE, this is the only supported desktop environment.
Once you log off, you will get a screen asking for a password in x2go, you can ignore this because you have an ssh key. The screen will look like this:
Just hit cancel and start the session over again.
Once you hit cancel above, you will get the session back on the right that you can click on again. If you are asked for a password, you will not be able to get into the session.
