Hello, I installed the ThinLinc server 4.16.0 on a RHEL 8.9 and all three services are running. But if I want to login from a remote computer (with client 4.16.0) the Session stops immediately after the selection of the Gnome type. What could be wrong? Thank you in advance.

It looks like ThinLinc is running fine, but something goes wrong when GNOME is starting. Do the system journal yield any clues to whats going on? Regards, Martin ---

No, sorry. No clues there that I can see. Are you able to get a local (graphical) console session working?
