Forward to container whole video adapter

[toby63]

Well, that depends:

• What software does your host use instead? Or is it headless?
  There are for example solutions available for Wayland as well (just search the forum).

Many methods (for X-forwarding) assume that you want to use a X-Server of the Host inside the container (this is e.g. because of better performance=GPU accerleration).

Your case seems to be the opposite .

According to this:

Discussion on running X11 applications from within LXD system containers

There is only a tutorial for LXC about running a X-Server inside a container (I haven’t looked at it):

XServer inside LXC container

alex9434 asked how to run Xserver inside an LXC container? My response is rather long, so I decided to put it in a separate thread. Four files are included below: The container’s config file. The container’s xorg.conf The container’s lightdm.conf A script to install lightdm, xorg etc in the container. All of the files except lightdm.conf are hardware-dependent, so you will need to adjust them. The hardware I used was an old laptop with intel integrated graphics. I have used this setup to…

Notice though that you probably also need to have devices like /dev/video on your host.
If you don’t have these devices, I would search for whether it is possible to run an X-Server on a pure server hardware.
Maybe Virtual machines would also work better in such a case.
Sry no expert .

Assuming this works, then you could use a remote-desktop software like vnc or ssh -x etc. to login to your containers desktop.

But maybe someone else has a better idea.
