Tips & Tricks

• Signal will be blurry on phosh (pinephone, Librem 5) becacuse of Xwayland scaling. To fix, run with wayland using these arguments: --use-gl=egl --enable-features=UseOzonePlatform --ozone-platform=wayland. Signal must be opened at least once in X11/Xwayland first (just by clicking the launcher) first.
• To add the above to the launcher shortcut:
  • mkdir -p ~/.local/share/applications ; cp /var/lib/flatpak/app/org.signal.Signal/current/active/files/share/applications/org.signal.Signal.desktop ~/.local/share/applications/
  • desktop-file-edit --set-key=Exec --set-value="flatpak run org.signal.Signal --use-gl=egl --enable-features=UseOzonePlatform --ozone-platform=wayland" ~/.local/share/applications/org.signal.Signal.desktop
• Use the View menu item to zoom out a few times. It makes Signal much less cramped.
• Ctrl+Shift+c will close the current conversation and reduce idle CPU usage significantly.
• Notification sounds and mic/camera usage can be enabled in settings.
