[lxc-users] xrdp in lxc 2.0 container

[Alex Clarke]

I'm having some issues getting an rdp connection into a lxc 2.0 container.

I've built xrdp and x11rdp from source, and I'm using Ubuntu mate as the
Desktop environment. using an unprivileged container, which from what I
understand is possible without audio and clipboard.

I can make a connection, and get to the xrdp login screen, but get a black
screen after logging in using x11rdp, and then the connection closes. Do I
need to pass anything on from the host to start this session?

journalctl -f output

I've split it into sections as to what's happening on screen.

this here seems to be where it's failing.
