X11 - RHEL 10.2 - ISOLATED Passthrough

Hoping someone can help me out with an issue I've been having for a long while.

I'm running RHEL 10.2 Gnome 49, trying to use an X application inside of a podman container with a custom network.

"podman network create --internal pod_dev"

I pass in all the environment variables and files that I know and what AI also says i need. I can not for the life of me get the x application to display.

It works in fedora 44, and Ubuntu, but RHEL 10 is kicking my butt.. if i do --net=host is am able to get the x application to work, but I have to have the container have its own IP.

And advice at all is appreciated, I've probably spent over 100 hours trying different combinations of flags and ways to run.

Does X11 need to be running on the host system? I ask because gnome on rhel 10 uses wayland by default. You might need to change it to x11, assuming gnome 49 supports x11 at all. I don't know which version but they are taking it out soon.

X11 is fully deprecated on 10. However, Xwayland still allows X processes to work, and for the most part I haven't had issues with Xwayland.

I believe gnome removed support in 48 or 49.

Yeah. I know about xwayland. I was just curious if this works with it. It wouldn't be the first time I've seen an X application not run right with it.

I know there is a wayland command we can use to export the gui with ssh. I used it only once and was quite straitforward. A quick google search should help you find it if you want to try.
