Error when adding graphics to LXC

“Cannot determine default video type”
What’s the problem? Is there a solution? I looked for a solution on the Internet with no luck. I searched on Google and couldn’t find anything.

Depends on how you installed LXC, and you should know that as a container access to graphics is not virtualized so you need to provide all the necessary pieces in the container (you can’t use the HostOS video).

See the post to the other thread you just posted asking how you installed LXC on your system.
