[lxc-users] LXD Based Container For Desktop Applications - Some Success - Help

yes, I have about 4 of those running - unprivileged :) And I've had a go
with TigerVNC (which supports 3d capabilities currently lacking in X2Go).
I can run current versions of KDE and Unity on Xephyr, which I currently
cannot with X2Go
But for this use case, I want desktop integration from an unprivileged
container. I have achieved it with LXC on Ubuntu 16.04... but was hoping
to be able to use LXD. It feels like I'm so close ... just missing
something, probably quite trivial once you know how ... I wish i knew how
Currently I have the following containers
- Mythtv Backend (unprivileged, but with special user mappings which
mean it can write to host devices when they're mounted in)
- Proxy with Openvpn and Dante
- Development - X2Go with Mate
- Browsing, semi secure, X2Go with Mate
- Desktop integrated browsing - Unsecure with Mate, on either Xephyr or
Host desktop BUT running as lxc-start ie. legacy formate
- Various other experimental containers, including one with KDE, X2Go,
Xephyr and TigerVNC
Somewhat surprisingly current KDE is quite useful with X2Go as long as
you autostart some applications, particularly dolphin and konsole ...
then others can be started. You just won't have the panels etc. I
haven't spent too much time with it because it's not close enough to
what I want to achieve.
