Comment 37 for bug 1951491

Tim,

Two "Thank-you"s for you:
    1. "spamming" elsewhere and here. Indeed, I got redirected here after I saw your comments at snapcraft forum
    2. Correctly specifying the bus address for the session by setting DBUS_SESSION_BUS_ADDRESS. This worked like magic! My Ubuntu 22.04 running KDE Plasma was almost unusable over x2go. I can't thank you enough!

This is the exact issue that appears when running any confined snap over x2go (or VNC as reported by others)
```
/user.slice/user-1000.slice/session-1.scope is not a snap cgroup
```
As it turned out, it was snapd not finding the bus path. For anyone looking for a quick fix, apply Tim's fix to your ~/.profile and you are good to go. Some snaps (like Firefox) requires re-installation to work.
