It is also possible to open a graphical desktop on Bilbo with X2Go. To do that, use the [same procedure as on Pyrene](https://git.univ-pau.fr/num-as/pyrene-cluster/-/wikis/1-Environment/1.2-Connection-to-Pyrene#graphical-mode-windows-linux-macos-x2go), but replace the Host name _pyrene.univ-pau.fr_ by **_bilbo.univ-pau.fr_**.
