My GUI App was designed to run on Ubuntu 18.04 Desktop VMs. I’m trying to migrate it to an LXD 4.0.2 container.
Both host and container runs Ubuntu 18.04 Desktop. Display works but just no keyboard or mice input.
There’s no GPU on the host as intended.
Here is the profile I’m using to launch it. Part of my troubleshooting is to add as many devices possible to rule them out.
lxc profile show lanprofile
config: {}

used_by:
- /1.0/instances/c1
After launching the container I run the following to get the display working.
lxc config device add c1 tty0 unix-char path=/dev/tty0
lxc config device add c1 tty7 unix-char path=/dev/tty7
lxc config set c1 security.privileged=true
lxc restart c1

1. Are the syntax in my lanprofile correct for adding devices? I’m suspicious about type: unix-char and can use some validation.
2. Why is my Xorg log stopping at Adding drm device (/dev/dri/card0)? I’m not even adding this device from host to container.
On the VM where everything works normally, this is what gets posted at this point in the log.
