Some environment variables, defined in hyprland.conf, don't show up in printenv or echo output

[izmyname]

Some environment variables, defined in hyprland.conf like AQ_DRM_DEVICES and XDG_SESSION_DESKTOP, don't show up in printenv and echo output. For comparison, here's my hyprland.conf env variables.

#using integrated GPU for rendering
#https://wiki.hyprland.org/Configuring/Multi-GPU/
#lspci | \grep -E 'VGA|3D'
#ls -l /dev/dri/by-path
env = AQ_DRM_DEVICES,/dev/dri/card1

#XDG specs
env = XDG_SESSION_DESKTOP,Hyprland
env = XDG_CURRENT_DESKTOP,Hyprland
env = XDG_SESSION_TYPE,wayland

#cursor
env = XCURSOR_THEME,catppuccin-mocha-dark-cursors
env = XCURSOR_SIZE,24
env = HYPRCURSOR_THEME,catppuccin-mocha-dark
env = HYPRCURSOR_SIZE,24

#forcing everything to run on native wayland
env = GDK_BACKEND,wayland
env = SDL_VIDEODRIVER,wayland
env = CLUTTER_BACKEND,wayland
env = QT_QPA_PLATFORM,wayland
env = MOZ_ENABLE_WAYLAND,1
env = EGL_PLATFORM,wayland
env = ELECTRON_OZONE_PLATFORM_HINT,wayland 

#other vars
env = QT_QPA_PLATFORMTHEME,qt6ct
env = _JAVA_AWT_WM_NONREPARENTING,1

Here's printenv output

e.g echo $AQ_DRM_DEVICES returns an empty string.

It's worth to mention, that:

1. This is a regression, as variables used to show up in the output on 0.43 and earlier.
2. Variables do their thing, despite their absence in the output.
3. The method of starting Hyprland (systemd service or by typing Hyprland in tty) doesn't matter.

uhhh... odd. Environment should be passed through with execl... Maybe I am missing something in posix

[izmyname]

Reopen this one, too, for further references or if it helps to solve some issues caused by it. This isn't really a problem, though, as variables still work.

[izmyname]

UPD: For uwsm users - just add exec-once = uwsm finalize to export those variables into environment. If some vars aren't exported (eg AQ_DRM_DEVICES, QT_QPA_PLATFORM) - just add them to the command as an argument (e.g, exec-once = uwsm finalize AQ_DRM_DEVICES QT_QPA_PLATFORM)

[autofool]

uwsm users should use systemd environment for variables. systemd-environemnt reads all files from $HOME/.config/environment.d/ on login. e.g.

/home/user/.config/environment.d/rust.conf
-----------------------------------------------------
RUST_HOME=$HOME/.config/rust
CARGO_HOME=$RUST_HOME/cargo
RUSTUP_HOME=$RUST_HOME/rustup

Plus, it expands the variables defined previously. For example, in hyprland if I echo $CARGO_HOME then the output will be $RUST_HOME/cargo while it should be /home/user/.config/rust/cargo.

[izmyname]

Both options seem to work. IMHO, hyprland.conf is good for graphical session -related vars (like electron, cursors, theming) and environment.d - for everything else.

Although, I use .zshrc for non gui-related vars.

[kai-tub]

I am using NixOS with home-manager and after updating today, I had to export the following PATHs via environment.d (systemd.user.sessionVariables):

"PATH" = "$PATH:/run/current-system/sw/bin/:/etc/profiles/per-user/<user>/bin/";

for fuzzel or any dispatchers to find the binaries.

[izmyname]

A small update - just transferred all my non-hypr vars from zshrc and hyprland.conf to environment.d, and it is, for sure, a way superior method to manage them.

upd: There's a downside, though. In order to apply changes, after changing a variable's value, one must reload the whole session.
