[SOLVED] Hyprland - No DISPLAY variable gets set

[dreamLogic]

Hi all. Forgive me as I'm having trouble doing clipboard stuff here on Wayland right now.

I am trying to use Hyprland as my main window manager and am launching it from tty after login.

Most things are fine except for things that need X.

I've used flatpak to install a package for example and when trying to run it it spits out:
Missing X server or $DISPLAY

I have the same issue with Steam (installed with emerge).
With Steam I get:
src/steamexe/updateui_xwin.cpp (339) : Could not open connection to X

I have xwayland installed and am using the nouveau video driver. I also have the following exports as environmental variables in my hyprland config:

XDG_CURRENT_DESKTOP=Hyprland
XDG_SESSION_TYPE=wayland
XDG_SESSION_DESKTOP=Hyprland

I have "exec-once = dbus-update-activation-environment --systemd WAYLAND_DISPLAY XDG_CURRENT_DESKTOP" in there as well as I have the hyprland xdg portal package installed.

Please let me know what other info any of you need.

If it's a nvidia issue, note that I am getting an AMD GPU shipped in tomorrow. I don't know if that will help or not.

DISPLAY is not set because that's an X-specific environment variable. Since you're not running X, you need to set it manually - e.g. to ":0" - before you update your D-Bus session bus environment via `dbus-update-activation-environment`, which you'll need to modify to include a reference to DISPLAY.

i'm not a Hyprland user myself, so hopefully someone else can explain how to do the preceding in the context of Hyprland (and hopefully update the Hyprland wiki page accordingly as well).

There should never be a need to manually set DISPLAY variable for X11 server.
Not to mention what variable should that even be if we do not know on which specific DISPLAY is X11 server registered? If that is single X11 server running it might be :0 or :0.0 as usually X11 servers when ran alone register as either of these two but still it is extremely unlikely it should be needed and even that it will work.

Here you mention running flatpak apps so maybe this is flatpak related issue. When you just open terminal under hyperland and run export | grep DISPLAY does it says there is DISPLAY?

If it does and you can run X11-only apps but for example in terminal app installed via flatpak it does not then it might be possible you need to check flatpak configuration.

Welcome to Gentoo @dreamLogic

i use only Hyprland without xwayland, but i'll try my best to help you anyway.

please show the output of - as User:

Hey all. I'm just at work until 5pm MST. I'll give you all the deets later today once I'm free.

I'm anxious as I'm getting a much better GPU today and want to get Steam up and running asap to check it out.

If we can't figure this out I can always just go with a vanilla Xorg setup, though I would prefer wayland if possible.

Edit:
Forgot to mention that I'm trying to run steam natively, not via Flatpak. So it's not just a flatpak issue.

Exposing my ignorance here but would I need xorg stuff actually installed? Perhaps this is the problem. I thought I read Xwayland is a server itself.

took it from my Hyprdots, installed on a separate disk, CachyOS with systemd.

i sometimes use other distros to try some things out, e.g. Endeavour OS, Garuda or CachyOS, regarding Hyprland.

and then if i like it, i implement it to my OpenRC System.

you also need more QT specific XDG options - look at Hyprdots dotfiles and compare it with yours.

you can also use the scripts for Clipboard with Rofi.

if it's not much to ask - can you please edit first your answer from today, because it's awful to scroll sideways - there's an edit button on the right side.



EDIT:

you also need https://wiki.hyprland.org/Useful-Utilities/Must-have/#authentication-agent

take your time and read https://wiki.hyprland.org/

i'll test you tomorrow to get sure you really know everything about Hyprland

Hey CooSee, do you know which QT XDG options I need. I'm lazy

I might set up a X window manager temporarily until I figure all the Hyprland stuff out.

I forgot to point out to everyone that I am using systemd if that helps.

So I got it working. I enabled all the environment stuff and went over the wiki on Gentoo and the Hyprland site and installed whatever they recommended.

The biggest thing though, which was probably the root cause of everything really is I didn't have the X flag enabled globally. I thought I could just enable it on the package.use file for Hyprland, but no, it has to be set globally for picking it up.

After doing a full @world rebuild steam now launches under Hyprland! Also my flatpak app.

glad to hear you got everything working.
