This week, I was writing tests for a module that configures my desktop and laptop, including installing and setting up Xorg and KDE and the SDDM display manager. I wanted to be able to test that they not only got installed, but actually ran without dieing - which required a graphincal environment (ideally, I’d visually confirm this as well).
To do this in Vagrant, you’d just add a
gui = true option to the
virtualbox provider in your Vagrantfile.
It isn’t documented anywhere, but I found
that Beaker has support for this as well; all you need to do is add
vb_gui: true in your node definition YAML.

Once that’s done, the VirtualBox VM will run with a graphical display enabled. This is probably only useful on a local machine or if you’re running on a remote host have you have access to and have vrdp enabled, but in some edge cases like my module, it’s useful.
