A real DP/HDMI unplug makes Hyprland tear down the layer-shell surfaces on the surviving monitor and not recreate them, so waybar and the wallpaper vanish there. A SIGUSR2 reload rereads waybar's config but does not recreate a bar that was already destroyed, so it left the laptop bar gone. Kill and restart waybar instead — a fresh process enumerates the current outputs and draws a bar on each — and add a settle delay before re-pushing the wallpaper so it lands on the settled geometry. Verified against a real DP-1 unplug: the LVDS-1 bar and wallpaper survive. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

|
|
# layer-shell surfaces on the surviving monitor and does not recreate them, so
|
|
# its waybar and wallpaper vanish. Watch Hyprland's event socket and, on either
|
|
# add or remove, re-push the wallpaper (setbg with no arg → all current
|
|
# outputs) and fully relaunch waybar. A SIGUSR2 reload is not enough — it
|
|
# rereads config but does not recreate a bar Hyprland already tore down — so
|
|
# kill and restart, which enumerates the current outputs and draws a bar on
|
|
# each. The event flaps (several add/remove lines per plug); the loop is
|
|
# sequential so each pass converges to one waybar. Hyprland emits both
|
|
# `monitoradded` and `monitoraddedv2`; match only the non-v2 forms so each side
|
|
# fires once. Runs as a Hyprland exec-once (see home.nix).
