Help would be much appreciated:
We are using Ubuntu Mate 18.04 and are accessing it either via VNC (local session) or via X2Go ("Custom Desktop" Command: MATE). The Ubuntu Mate user is the same.
When accessing it via X2Go, it appears that this "remote user" does not have the same priviliges as the local user via VNC OR connecting via X2Go to local desktop , even though it is exactly the same user who is logged in.
For example, when using Seahorse, it does not show / properly work with passwords when accessed during an X2Go New Mate session. (See screenshot in additional post further below)
When accessing via VNC or OR connecting via X2Go to local desktop, network credentials can be edited and stored in Seahorse.
See attached screenshot VNC
