X11 remote graphics does not work

Remote graphics requires tunneling X11 through SSH using the -X flag. On Linux, connect to e.g. Roihu using:

ssh -X <your-user-name>@roihu-cpu.csc.fi

An error may occur if you have run out of disk quota.

Another (better) way to run remote graphics is to use a remote desktop through the Roihu web interface.

For more details, see our instructions for graphical connections.
