Wayland
configuration → server → wayland → wayland

Desktop streaming (e.g. via bbb or jitsi)

pulseaudio did not work for me and had to be replaced with pipewire, because it brings these systemd user services to enable desktop streaming:

  pipewire-media-session.service
  pipewire-pulse.service
  pipewire.service

Graphical Java applications

Do not start and say: Error Can't connect to X11 window server using 'wayland-1'

Run it under Xwayland, e.g. with env DISPLAY=:0 java program.java

Window appears, but is blank

If the window is empty or if it only shows its controls after resizing, try setting the environment variable: _JAVA_AWT_WM_NONREPARENTING=1

Fonts are ugly

Try adding -Dawt.useSystemAAFontSettings=on to _JAVA_OPTIONS

Integration into GTK/Gnome look

Add -Dswing.defaultlaf=com.sun.java.swing.plaf.gtk.GTKLookAndFeel to _JAVA_OPTIONS

xfce4 components are crashing?

Try starting them with env GDK_BACKEND=x11, e.g GDK_BACKEND=x11 xfce4-settings-manager

set cursor theme

If it is a native Xorg application, it has to be configured like one:

GTK gsettings set org.gnome.desktop.interface cursor-theme "Hackneyed"

# ~/.config/gtk-3.0/settings.ini
[Settings]
gtk-cursor-theme-name=Hackneyed
gtk-cursor-theme-size=24

# ~/.config/gtk-4.0/settings.ini
[Settings]
gtk-cursor-theme-name=Hackneyed
gtk-cursor-theme-size=24
