One solution could be to switch to full screen and then activating
resize mode. Normally this is done
by pressing ctrl-alt-r. Unfortunately this broken currently so you
have to do some adjustment first: Open /usr/bin/x2gostartagent in an
editor and change this line
   export NX_CLIENT="${X2GO_LIB_PATH}/x2gosuspend-agent"
to
   export NX_CLIENT="/bin/true"

I have not used connecting to local sessions for a long time so I am
not sure if the resize mode is working then.

We are currently trying to find the reasons for several crashes. This
one sounds like https://github.com/ArcticaProject/nx-libs/issues/679

Oh dear, someone else reported this, but I have no idea what is
causing this. See here:

I have implemented something like that but it is not fully working
yet. And it is completely untested with windows.
