GUI apps in LXD (Archlinux Host)

[simos (Simos Xenitellis)]

I managed to replicate the issue; indeed with lxc console mycontainer something is different and the X application does not start.

Here is the output

$ lxc console mycontainer
To detach from the console, press: <ctrl>+a q

Ubuntu 18.04.1 LTS mycontainer console

mycontainer login: ubuntu
Password: *************

ubuntu@mycontainer:~$ xclock
Error: Can't open display: 
ubuntu@mycontainer:~$ 

Until I figure out what’s going on, you can follow the following guide,

Useful lxc command aliases

Thanks again! Here is what I would be suggesting to users. Something missing in LXD is a simple command that gives you shell access to a LXD container, under the non-root account of the container. The Ubuntu containers from the ubuntu: repository have the ubuntu account (created by cloud-init instructions as the container is first started). I used to suggest to lxc exec mycontainer -- sudo --user ubuntu --login. This can be aliased, with an alias named ubuntu so that a user can just run lxc u…

and get the shell with

lxc ubuntu mycontainer
