调研方向
阅读 dotfiles/.config/hypr/conf/autostart.lua，同时查看 ml4w-autostart 以及调用 run_matugen 和 reload_waybar 的 ml4w-wallpaper 代码。追踪两条启动路径，并检查现有日志或测试（如果有）。确保主题设置完成后 Waybar 只启动一次，然后确认默认的 Waybar 登录过程不再记录第二次重启，且状态栏不再闪烁。

描述
Describe the bug
On every login Waybar is started twice. The first instance shows up with the previous colors and some modules not ready yet. It is then killed and a second instance is started a moment later, so the bar visibly disappears and comes back.
There are two launches:
dotfiles/.config/hypr/conf/autostart.luastarts Waybar directly:-- Start waybar hl.exec_cmd(HOME .. "/.config/waybar/launch.sh")- A few seconds later
ml4w-autostartrunsml4w-wallpaper "<cache>" --skip-wallpaper, which callsrun_matugenand thenreload_waybar. That function doeskillall waybarand runslaunch.shagain.
Looking at the history, this looks like an overlap between two changes made two days apart:
- c470e824 (Jun 23) added the Waybar launch to
autostart.lua. At that pointml4w-wallpaperwas skipped entirely when the awww cache existed, so the bar had to be started from somewhere else. - a4a1bebd (Jun 25) changed
ml4w-autostartto always runml4w-wallpaper ... --skip-wallpaperfor theming. Since then Waybar is also (re)started byreload_waybar, so the launch inautostart.luais redundant. - 0d676f10 (Jul 14) changed
reload_waybarfrompkill -SIGUSR2 waybartokillall waybar, which makes the restart visible as a flicker.
The issue is present from 2.14.0 up to 2.17.
Steps to reproduce
- Use Waybar as the status bar (
~/.config/ml4w/settings/statusbar=waybar) with the default autostart. - Make sure the awww cache exists (any normal login after the first one).
- Log in to Hyprland.
- Waybar appears, disappears for a moment and then appears again. The autostart log in
~/.local/state/ml4w-os-hyprland/showsWaybar is currently running.followed byWaybar restarted.
Expected behavior
Waybar should start only once at login, already themed by matugen.
A possible fix is to drop the launch from autostart.lua and let ml4w-wallpaper start Waybar after matugen. Another option is to keep it there and have reload_waybar skip the kill and relaunch when it is called from ml4w-autostart.
Distribution
