Bug Description
This symptom is observed with Ubuntu Mate 20.04.
1. Create /etc/lightdm/
[XDMCPServer]
enabled=true
and restart lightdm.
2. Login as a normal user from keyboard.
3. Login as the same user as 2 from XDMCP gives
"Could not acquire name on session bus"
and I cannot login from XDMCP.
Without Step 2, XDMCP login succeeds.
The same symptom is reported at
https:/
which recommends removal of "dbus-user-session" Ubuntu package.
I worked around the above issue by putting
"unset DBUS_SESSION_
in /etc/X11/
The same issue is also reported at
