Waybar doesn't autostarts consistently on Hyprland

[aguyfromuranus]

Waybar 0.11.0, Hyprland 0.44.1, OS Artix Linux with OpenRC

When autostarting Waybar with Hyprland's "exec-once" command, one of the three things can randomly happen:

1. The bar won't appear at all

2. The bar will appear, but without the hyprland modules

3. The bar will appear with all the modules and work as normal

Starting Waybar after Hyprland boots works as intended. Here are the modules I use:

    "modules-left": [
        "hyprland/workspaces"
    ],
    "modules-center": [
        "clock"
    ],
    "modules-right": [
        "pulseaudio",
        "custom/net",
        "custom/mounts",
        "cpu",
        "memory",
        "hyprland/language"
    ]

Unable to receive desktop appearance: GDBus.Error:org.freedesktop.DBus.Error.UnknownMethod: No such interface

Maybe the error is here. You can try to use the default configuration to see if it can be started.

The hyprland modules seem to be the culprit, as commenting them out and not touching anything else solves the problem. I'll make an issue at hyprland and see what they'll say

[AlphaNecron]

Hm so you can try making a script to poll for Hyprland availability? This may be useful

i just booted to find Waybar missing. i start waybar with exec-once, even though i use uwsm to launch Hyprland (just haven't gotten around it yet).

waybar coredumped with the following preceding lines:

arch kernel: traps: waybar[1343] general protection fault ip:7f0a689ab2a0 sp:7f0a6131f3d0 error:0 in libstdc++.so.6.0.33[7f0a68897000+14d000]

arch systemd-coredump[1345]: Process 1190 (waybar) of user 1001 terminated abnormally with signal 11/SEGV, processing...

the last waybar-related line stated [info] Hyprland IPC starting just like stated in the "no bar" case in #3742 (comment)

i am not sure if this info is relevant. however, i can also attach the coredump file if necessary.

is #3822 or #3826 relevant?

PS: hyprwm/Hyprland#8394 (comment) seems to suggest just launching it as a user service should fix the issue

just a note: i switched to starting waybar as user service for last 4 days, and i still find the hyprland/workspaces module missing at times on startup.
