YubiKey lock screen

What

I'm trying to make my fedora desktop lock the screen and unlock when it sees my key in.

HOW

Get the serial, idVendor, idProduct of the thing.

udevadm info -a -p $(udevadm info -q path -n /dev/hidraw0)

Create a /etc/udev/rules.d/85-screen-lock-toggle.rules

SUBSYSTEM=="usb", ACTION=="remove", ENV{ID_VENDOR_ID}=="1050", ENV{ID_MODEL_ID}=="0010", ENV{ID_SERIAL_SHORT}=="0001484196", RUN+="/usr/local/bin/gnome-lock enable"

Also you should probably reload the rules:

udevadm control --reload-rules

And you should create the 2 scripts:

~# cat /usr/local/bin/gnome-lock
#!/bin/bash
log="/tmp/yubi_lock_log"
echo "$(date) $(whoami) '$0' '$1'" >> ${log}

user=`ps aux | grep gnome-screensaver | head -n 1 | awk '{print $1}'`
export DISPLAY=":0"
if [ -n $user -a "$1" == "enable" ]
then
        sudo -u ${user} /usr/bin/gnome-screensaver-command -l >> ${log} 2>&1
fi
