Answer 2

Use xdotool instead:

sudo apt-get install xdotool

Then, in a bash loop like this

while true ; do
    DISPLAY=:0.0 xdotool key Shift_L   # send a "harmless" keypress to Xorg
    sleep 5                            # wait a little bit and do it again
done

Answer 3

You might want to disable power management in gnome-control-center.
