Hi together,
I use x2go for several years now and set up a new workstation with arch linux and x2go server.
On the client side I use the x2go client on windows to start a LXDE session on the workstation.
When I try to connect to the old workstation, everything is working as expected.
When I connect to the new workstation, a new black windows is started and after some seconds, the windows is closed.
I do not get an error on the client side and in the server journal this i everything I get:

The difference between the old and the new workstation is, that the old one has a nvidia gpu and the new one uses the intel gpu on the cpu.
Since there is no error message, I'm nealy clueless.
Help would be very appreciated!
Thanks
