Using generic display names doesn't work for my laptop's built-in display

[zsolt-donca]

Describe the bug
When I am using azote with the "Use generic display names" feature, it doesn't set the background for my laptop's built-in display. Running .azotebg it gives me this:

❯ ./.azotebg
2022-06-17 10:52:50 - 2022-06-17 10:52:50 - [swaybg/main.c:256] Could not find config for output eDP-1 (Sharp Corporation 0x1516)

My .azotebg at the moment is:

❯ cat ./.azotebg
#!/usr/bin/env bash
pkill swaybg
swaybg -o 'Dell Inc. DELL S2817Q J42MC74R273M' -i "/home/zdonca/Pictures/wallpaper/swaying_tree_to_right.png" -m fill &
swaybg -o 'Sharp Corporation 0x1516 Unknown' -i "/home/zdonca/Pictures/wallpaper/swaying_tree_to_right.png" -m fill &

And my outputs are:

❯ swaymsg -t get_outputs

    ...

If I run swaybg without the word "Unknown" in the name of the output, it actually works.

To Reproduce
Steps to reproduce the behavior:

1. Have an external display connected to my laptop.
2. Run Azote, and check the "Use generic display names" checkbox.
3. Apply the backrounds.
4. Notice that the built-in display doesn't have a background set.

Expected behavior
My built-in display should have a background set when using the "Use generic display names" feature. I need this feature because the id of my external monitor doesn't stay consistent for whatever reason, and it varies between DP-5 and DP-8.

Desktop (please complete the following information):

• Arch Linux
• Latest development builds of sway and wlroots.

Azote version (please state it clearly if you use -git version):

❯ pacman -Qi azote
Name            : azote
Version         : 1.9.4-1

No idea. As well .azotebg as the swaymsg -t get_outputs output contain the very same output name: Sharp Corporation 0x1516 Unknown. It may be impossible to debug this issue on my hardware.
