When watching a movie on a laptop, it should cleverly disable its screen:
- If no external screen is plugged, don't disable.
- If a modifier key is used to open the movie, don't disable.
- If an external screen is plugged and no modifier is used, disable the laptop screen.
- When the media player exits, restore the laptop screen.
I've written the following script:
#!/bin/bash if [ "$(cat /sys/class/drm/card0-VGA-1/status)" = connected ] then xrandr --output eDP1 --off vlc "$1" while [ "$(pidof vlc)" > 0 ] do sleep 1 done xrandr --output eDP1 --auto --below VGA1 else vlc "$1" fi
eDP1 represents the laptop screen, VGA1 the external screen. The script is used by associating movie files in
~/.local/share/applications/mimeapps.list with the following desktop file:
[Desktop Entry] Name=VLC Comment= Exec=path/to/the/above/script Icon=vlc Terminal=false Type=Application StartupNotify=true
Can you suggest a way to modify the script or the desktop file, or any other way to check for a modifier key - the only restriction being that a single action must be used to open the movie.
