Notes.md

Requirements

• You need to have a working notify-send
• You need to install xpub for getting current user session variables Github

Resources

• http://reactivated.net/writing_udev_rules.html
• https://wiki.archlinux.org/index.php/udev#Triggering_desktop_notifications_from_a_udev_rule
• http://www.wulftone.com/2014/03/26/make-usb-keyboard-stay-awake-and-disable-laptop-internal-keyboard

Extra

• You can use journalctl to check the udev logs and see if something is not working
• Tried using a systemd service instead of RUN+= on udev rules but didn't managed to pass the variables of the current session to show notifications.

Thanks. Can this be helpful for Bluetooth keyboard?
