LXQt Desktop under Wayland

General files and dotfiles for a LXQt Wayland session. LXQt 2.0 has native wayland support in all its elements now but some features are not ready yet.

Folder/Content

• start_scripts: startlxqt<compositor> : ENV variables, import settings, start compositor
• wayland-sessions: <compositor>_lxqt.desktop : Entry in SDDM
• scripts: some tools for autostart and else
• config : configurations for LXQt < 2.0 and other components
• AUR : PKGBUILD for lxqt-panel and desktop file

lxqt-panel

• Working in labwc, sway, hyrpland, kwin_wayland, wayfire and probably all wroots based compositors. Until LXQt v2.1 comes out compiling is needed using git checkouts:

  • Wlroots-based compositors + kwin (PKGBUILD available in AUR folder). Copying lxqt-panel.desktop manually to /etc/xdg/autostart is needed.

  • kwin_wayland only.

For more details and workarounds see lxqt-panel page.

Starting LXQt Session

• Copy the desired file(s) from wayland-sessions to /usr/share/wayland-sessions/ (if using a display manager like SDDM). Copy the desired scripts from startup_scripts to /usr/bin/ or /usr/local/bin and make them executable.

• Labwc and kwin_wayland start scripts will start lxqt-session automatically; in other compositors executing lxqt-session or some of its components has to be configured in their settings file. For both complete installation setups are available, see "Screenshots" below. To exit also the compositor after exiting LXQt && <exit_command> should be used.

• startlxqt<compositor> scripts can be executed also directly in tty.

• $XDG_CURRENT_DESKTOP is now set to LXQt:<compositor including also :wlroots if not kwin-wayland.

• Basically similar script could work for any compositor, see their last line.

• The provided startup scripts use the default configuration files for the compositors. All wlroots-based compositors have options to use different location if different settings are desired.

Notes and News

• Multiple user session are possible alongside a normal session started by sddm by simply login on tty and using one of the start scripts. Screenlocking is not handled though. Using kwin_wayland multiple user sessions are fully supported.
• Modulelxqt-globalshortcuts loads but cannot register shortcuts on wayland. Global shortcuts are handled by the compositor only.
• Some applications in autostart may not work under wayland and/or can cause high cpu usage - see "scripts" folder for a selective autostart of applications depending on session type x11/wayland. For wayland-only applications useing the autostart settings from the compositor is recommended.
• Qterminal's dropdown mode is supported now in git. Adding manually a hotkey for qterminal -d in compositor settings is needed.
• LXQt screenlock settings are supported now in wayland with liblxqt-git. Using kwin_wayland screenlocking is provided by the compositor while swaylock, waylockand hyprlock can be used in wlroots-based compositors. In ~/.config/lxqt/session.conf:

[General]
__userfile__=true
...

lock_command=slock
lock_command_wayland=swaylock

For kwin_wayland the setting is loginctl lock-session.

Screenshots and Annotations

Labwc (stacking)

See: lxqt-labwc-session.

Kwin_wayland (stacking)

See lxqt-kwin-session.

Wayfire (stacking)

Basic settings in wayfire.ini:

[autostart]
autostart_wf_shell = false
background = swaybg -i /usr/share/lxqt/wallpapers/origami-dark.png
lxqt_session = lxqt-session && killall wayfire

[command]
command_launcher = lxqt-runner
binding_launcher = <alt> KEY_SPACE

Exists a configation GUI tool WCM (wayfire configuration manager). In wayfire 0.8.1 lxqt-runner doesn't get focus automatically.

Sway (tiling)

Basic Settings:

exec lxqt-session && sway exit

for_window [app_id="^lxqt-.*$"] floating enable
for_window [app_id="^lxqt-.*$"] floating enable

bindsym alt+space exec lxqt-runner

In sway 1.9 lxqt-runner and qterminal's dropdown don't get keyboard focus automatically.

Hyprland (tiling)

Basic settings needed in hyprland.conf:

monitor=,preferred,auto,1

env = QT_QPA_PLATFORMTHEME,lxqt
env = QT_PLATFORM_PLUGIN,lxqt
env = XDG_MENU_PREFIX,lxqt-
env = XDG_CURRENT_DESKTOP,LXQt:Hyprland:wlroots

exec-once=lxqt-session && hyprctl dispatch exit

windowrule = float,^(lxqt-.*)$
windowrule = float,^(pavucontrol-qt)$
windowrule = float,^(sddm-conf)$
windowrule = float,^(pcmanfm-qt)$
windowrule = float,copyq

3rd party tools

• swaybg : background image (below desktop)
• swayidle; swaylock : lock screen
• Panels/bars:
• sfwbar : Source taskbar and much more
• yatbfw Source: taskbar, clock, quicklaunch
• waybar : taskbar, notification area, cpu/#windowrule = float,^(cmst)$ windowrule = float,io.github.martinrotter.rssguardram/temp monitor, keyboard layout display For keyboard-state working make sure your user is member of the "input" group. Some icons need "font-icon" and "font-awesome" to be displayed.
• wlrctr and wtype : for some keybindings - especially open applications menu in lxqt-panel
• wdisplay: Screen management GUI, see wdisplay
• clipman, dmenu, wl-clipboard : cliboard manager (configuration see wayfire.ini)
• grim,slurp : screenshots Example configuration
• wshot GUI for screenshots, see wshot
• wev : xev for wayland
• wayfire plugin for per application keyboard layout switch
• gammastep replacement for redshift
• wvkbd virtual keyboard

Tipps and Tricks

• Swipe to change workspace ~/.config/libinput-gestures.conf (for shortcuts "C-A-left|right" in labwc)

gesture: swipe left 3   wtype  -M ctrl -M alt -P right
gesture: swipe right 3 wtype  -M ctrl -M alt -P left

Using Sway swaymsgcan be used:

gesture: swipe left 3   swaymsg -t command workspace next_on_output
gesture: swipe right 3  swaymsg -t command workspace prev_on_output

Add libinput-gestures-setup start to autostart.

• Screensaver:

In autostart:

swayidle before-sleep swaylock timeout 300 'feh -rzsZFD 8 --draw-exif --draw-tinted ~/path/to/folder' resume 'killall feh'

• Dim inactive windows: see scripts.

• Exit gently also applications started by shortcut by the compositor when exiting lxqt-session. Example for labwc:

    <keybind key="W-k">
      <action name="Execute" command="pcmanfm-qt '/usr/share/applications/org.keepassxc.KeePassXC.desktop'" />
    </keybind>

• Featherpad single window doesn't focus if already open: copy featherpad.desktop from /usr/share/applications to to ~/.local/share/applications and changed the line

Exec=bash -c "featherpad %U && wlrctl window focus featherpad"

• Telegram does not open multimedia files

If images and video do not open: unset "animation" and eventually "opengl" in Preferences > Advanced.
