Short of a re-image does this give a hint for a fix? Uninstall and reinstall X2go, removal and regeneration of users .x2go directory also didn't help.

We have this issue on one PC, trying to reproduce elsewhere, and unable to so far. The issue is that when we run a single application we get a fleeting error after log in that it cannot set the DISPLAY and the session is immediately suspended.

On this PC, PuTTY with X forwarding enabled and manually running the same vcxsrv install works.

The same user to the same Scientific Linux 7 remote server from a different PC with the same settings and versions of software works.

Any ideas what else I should try?

Thanks,
