LXQt Panel on Wayland Compositors

Hacks and workarounds for lxqt-panel on wayland.

The lxqt-panel v.2.0 doesn't include yet a taskbar plugin for wayland. It's recommended to compile the work-in progress lxqt-panel-git. For Arch AUR can be used.

Replacements for widgets

Desktop cycler/switcher

Completely working with kwin_wayland. Under sway or Hyprland 'swaymsgorhyprctl dispatch` commands can be used.

Workaround: Configure shortcuts for go to left|right and/or go to <number>, examples C-A-left|right;C-A-1|2|3 and make sure to have wtype installed.

screenshot desktop switcher

  • First method, cycling:
    • Create desktop_left.desktop in ~/.local/share/applications/
    • Add a "quicklaunch" widget to the panel and drag this file into it, and again the same for "right" values.
[Desktop Entry]
Name=Desktop left
GenericName=Switch to left workspace
Comment=
Exec=wtype -M ctrl -M alt -P left
Type=Application
Icon=/usr/share/lxqt/themes/Arch-Colors/arrow-left.svg
Terminal=false

  • Second method, workspace cycling:

    • Add 2 or more "custom command" widgets to the panel and configure them like that:
    • echo → (or > or some text)
    • left click or mouse wheel command wtype -M ctrl -M alt -P right
    • no repeat

  • Second method, workspace switcher:

    • command: echo workspacename or echo 1
    • left click: wtype -M ctrl -M alt -P 1

Keyboard state/layout indicator

For numlock the value in /sys/class/leds/input3::numlock/brightness can be used in a customcommand plugin, similar for capslock. Note: The number (3) can be a different one on your system. This needs

XKB_DEFAULT_LAYOUT=us,de
XKB_DEFAULT_OPTIONS=grp:alt_shift_toggle,grp_led:scroll

in labwc/environment or other compositors config files.

if [ "$(cat /sys/class/leds/input3\:\:numlock/brightness)" == "1" ]; then echo 'N';else echo ' ';fi

If you are using only 2 keyboard layouts and don't need a scrollock indicator a layout indicator can be added in the same way to the panel. in compositor configuration set the xkb_options :to grp:alt_shift_toggle,grp_led:scroll and in the custom command plugin:

if [ "$(cat /sys/class/leds/input3\:\:scrolllock/brightness)" == "1" ]; then echo ' DE';else echo ' US'; fi

For more than 2 layouts see togglelayout (labwc only but could be adapted to others).

Colorpicker

Install hyprpicker and create a colorpicker.desktop file in `~/.local/share/applications:

[Desktop Entry]
Name=colorpicker
GenericName=Pick color from screen
Comment=
Exec=bash -c "hyprpicker -a && notify-send -a colorpicker -i colorpicker -t 3000 'Color value copied to clipboard'"
Type=Application
Categories=Graphics;Utility;
Icon=colorpicker
Terminal=false

Call it from runner/mainmenu or add it to a "quicklaunch" widget on the panel.

Show Desktop Button

Full working with kwin_wayland

On wayfire in wayfire.ini configure a shortcut, add it as wtype -M alt -P d in a "custom command" widget, icon=desktop.

[wm-actions]
...
toggle_showdesktop = <alt> KEY_D
...

On labwc you can use wlrctl toplevel minimize state:inactive && wlrctl toplevel minimize state:active as command in the custom command widget but this will just minimize all applications but not toggle it.
