Run mwm # mwm Error: Can't open display: 0.0 I have set display to 0.0 If you want the LXC container to be a xserver, then there is no need to start X in it :) That is only needed on the client (your workstation), that you run like an old-fashioned X-terminal. Just configure xdm to allow remote login. At 'boot' of the container, do a /etc/init.d/xdm start that is enough. From your workstation do either: X -query ip-number of xserver or: X -indirect ip-number of xserver depending on the configuration of xdm. See: http://tldp.org/HOWTO/XDM-Xterm/index.html Remove your /etc/init.d/rcS (in Debian that is, don't know if fedora uses that too) and create a new minimal one that just starts your sshd (so you have a loginmethod for troubleshooting) and xdm. Perhaps you need to set up your default gateway in that rcS file too. Nothing else needs to be started.
