SwayOSD

A OSD window for common actions like volume and capslock.

This is my first time coding in Rust so fixes and improvements are appreciated :)

Features:

• LibInput listener Backend for these keys:
  • Caps Lock
  • Num Lock
  • Scroll Lock
• Input and output volume change indicator
• Input and output mute change indicator
• Customizable maximum Volume
• Capslock change (Note: doesn't change the caps lock state)
• Brightness change indicator

Install:

There's a new LibInput watcher binary shipped with SwayOSD (swayosd-libinput-backend) which can automatically detect key presses, so no need for binding key combos. The supported keys are listed above in Features

Through Meson

# Please note that the command below might require `--prefix /usr` on some systems
meson setup build
ninja -C build
meson install -C build

AUR

Available on the AUR thanks to @jgmdev! (Don't open a issue here about AUR package)

• swayosd-git

Usage:

SwayOSD LibInput Backend

Using Systemd: sudo systemctl enable --now swayosd-libinput-backend.service

Other users can run: pkexec swayosd-libinput-backend

Sway examples

Start Server

# OSD server
exec swayosd-server

Add Client bindings

# Sink volume raise optionally with --device
bindsym XF86AudioRaiseVolume exec swayosd-client --output-volume raise
# Sink volume lower optionally with --device
bindsym XF86AudioLowerVolume exec  swayosd-client --output-volume lower --device alsa_output.pci-0000_11_00.4.analog-stereo.monitor
# Sink volume toggle mute
bindsym XF86AudioMute exec swayosd-client --output-volume mute-toggle
# Source volume toggle mute
bindsym XF86AudioMicMute exec swayosd-client --input-volume mute-toggle

# Volume raise with custom value
bindsym XF86AudioRaiseVolume exec swayosd-client --output-volume 15
# Volume lower with custom value
bindsym XF86AudioLowerVolume exec swayosd-client --output-volume -15

# Volume raise with max value
bindsym XF86AudioRaiseVolume exec swayosd-client --output-volume raise --max-volume 120
# Volume lower with max value
bindsym XF86AudioLowerVolume exec swayosd-client --output-volume lower --max-volume 120

# Sink volume raise with custom value optionally with --device
bindsym XF86AudioRaiseVolume exec  swayosd-client --output-volume +10 --device alsa_output.pci-0000_11_00.4.analog-stereo.monitor
# Sink volume lower with custom value optionally with --device
bindsym XF86AudioLowerVolume exec  swayosd-client --output-volume -10 --device alsa_output.pci-0000_11_00.4.analog-stereo.monitor

# Capslock (If you don't want to use the backend)
bindsym --release Caps_Lock exec swayosd-client --caps-lock
# Capslock but specific LED name (/sys/class/leds/)
bindsym --release Caps_Lock exec swayosd-client --caps-lock-led input19::capslock

# Brightness raise
bindsym XF86MonBrightnessUp exec swayosd-client --brightness raise
# Brightness lower
bindsym XF86MonBrightnessDown exec swayosd-client --brightness lower

# Brightness raise with custom value('+' sign needed)
bindsym XF86MonBrightnessUp  exec swayosd-client --brightness +10
# Brightness lower with custom value('-' sign needed)
bindsym XF86MonBrightnessDown exec swayosd-client --brightness -10

Notes on using --device:

• It is for audio devices only.
• If it is omitted the default audio device is used.
• It only changes the target device for the current action that changes the volume.
• You can list your input audio devices using pactl list short sources, for outputs replace sources with sinks.

Brightness Control

Some devices may not have permission to write /sys/class/backlight/*/brightness. So using the provided packaged udev rules + adding the user to video group by running sudo usermod -a -G video $USER, everything should work as expected.
