# LANG=en_EN ls -al /tmp/.X11-unix/X0
ls: cannot access /tmp/.X11-unix/X0: No such file or directory

Xorg works fine, but because of lack of this socket GUI applications doesn't work from lxc containder that mounts this folder. When I check that around 1 month ago it was ok. Have I broken something?

EDIT:

For what I see after reboot socket is there on host, but gets removed after I start lxc container.

EDIT2:

It happens when I start lxc container with Ubuntu inside, when I start containder with archlinux it's ok.

Re: /tmp/.X11-unix/X0 is removed from host after strting lxc with Ubuntu

I mount /tmp/.X11-unix as readonly, it prevents guests from deleting files from it:

lxc.mount.entry = /tmp/.X11-unix tmp/.X11-unix none bind,ro,optional,create=dir
