[X2Go-User] Performance on external monitor

[Jonah Benton]

Resolved! For future reference: I disable Compositing in the x2go sessions
because it makes XFCE unusable. I had ALSO disabled Compositing in the
master session. Re-enabling it in the master resolved the performance
issues in the x2go sessions on the external monitor. Who knew?

Cheers,

Jonah
