Error: cannot open display: :0

No response

Anything else?

I am running Asahi Fedora Linux on MacM1 hardware with Hyprland
Some of my host ENV if it may help

Hi @WBP20,

You need to install X11 server on your Linux host.

https://wiki.archlinux.org/title/xorg
https://archlinux.org/packages/extra/x86_64/xorg-xhost/

[Dramelac]

Did you have warning or error messages when creating your container ?

[WBP20]

@QU35T-code is it mandatory to install X11 server ? Xwayland could not be sufficient ?

@Dramelac when creating new container (test), i have this error message :

[D] Adding xhost ACL to local:exegol-test
Authorization required, but no authorization protocol specified
xhost:  unable to open display ":0"

[QU35T-code]

Oh yes, I had forgotten that. Wayland should be supported by exegol, @Dramelac will give you more information !

[Dramelac]

Hello @WBP20
It seems like your X11 server need authentication (through xauth) which isn't supported by Exegol for the moment unfortunately.

Regarding wayland, it should work but i can see it hasn't been connected to your container... Can you create a new container in debug mode (-vvv) and share the full output ?
Thank you !

[WBP20]

Ok i think i know. Because you use sudo to run exegol, wayland env var are missing.
Try to create a new container with sudo -E exegol start newcontainer light and wayland should work.

Hi @Dramelac, I still have the error message, even through wayland env variables seem be forwared.

The issue has been solved after allowing docker/exegol to be executed with user (without sudo).
