Hello Ulrich
The directories in /tmp get created automatically every thime I attempt a session (and before you ask, they are owned by my user and group)
The links in my home are also fine:
lrwxrwxrwx. 1 danielk computer 59 Oct 16 17:39 C-danielk-50-1539704304_stRTERMINAL_dp24 -> /tmp/.x2go-danielk/C-danielk-50-1539704304_stRTERMINAL_dp24
ls -al /tmp/.x2go-danielk/C-danielk-50-1539703799_stRTERMINAL_dp24
total 24
drwx------. 2 danielk computer 4096 Oct 16 17:30 .
drwxr-xr-x. 11 danielk computer 4096 Oct 16 17:55 ..
-rw-r--r--. 1 danielk computer 516 Oct 16 17:30 options
-rw-------. 1 danielk computer 825 Oct 16 17:30 session.log
-rw-r--r--. 1 danielk computer 12 Oct 16 17:30 sshd.pid
-rw-r--r--. 1 danielk computer 8 Oct 16 17:30 state
That was my first thought, but alas.

Hello
After some user's session got broken due to a client/server incompatibility, the user deleted all their session data and then told me they can not log in at all anymore. At first I could not see any problem (everything worked as expected for me), but when I deleted my own /tmp/.x2go-danielk directory, I started having the exact same problem.
The error I get is:
Agent output: "Failed to start X2Go Agent session with ID danielk-50-1539704304_stRTERMINAL_dp24. X2Go Agent terminated unexpectedly. Aborting session startup. The complete relevant last part of the debug log is pasted below.
The session.log for this session contains the error
Error: Aborting session with 'Unable to open display 'nx/nx,options=/tmp/.x2go-danielk/C-danielk-50-1539704304_stRTERMINAL_dp24/options:50''.
Do you have any idea how I can get this working again. It appears to me that something is not functioning accordingly with the session management, because the session state file remains in state STARTING and if I try logging in again then I get asked whether I want to terminate or suspend the running session (can't resume)
Thanks for any help.
