While trying to figure out how to get one of these to work I noticed on the elagost server [for Signal desktop flatpak] a nice little note that might interest some:
Tips & Tricks (click to expand)
- Signal will be blurry on phosh (pinephone, Librem 5) becacuse of X11. 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: copy /var/lib/flatpak/app/org.signal.Signal/current/active/files/share/applications/org.signal.Signal.desktop to ~/.local/share/applications/ and change the Exec line to this: Exec=flatpak run org.signal.Signal --use-gl=egl --enable-features=UseOzonePlatform --ozone-platform=wayland - 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.
