I want to have my touchpad disabled automatically when an external mouse is connected and enabled when there is none. I have tried using touchpad-indicator
but that fails in cases when the computer has been put to sleep with a mouse connected and awoken with the mouse disconnected.
I have tried to make the following script into a daemon to solve this issue but I can't get it to work:
#!/bin/bash
declare -i TID
declare -i MID
TID=`xinput list | grep -Eo 'Touchpads*id=[0-9]{1,2}' | grep -Eo '[0-9]{1,2}'`
MID=`xinput list | grep -Eo 'Mouses*id=[0-9]{1,2}' | grep -Eo '[0-9]{1,2}'`
if [ $MID -gt 0 ]
then
xinput disable $TID
else
xinput enable $TID
fi
I tried start-stop-daemon -S -x ./myscript.sh -b
and setsid ./myscript.sh >/dev/null 2>&1 < /dev/null &
and nohup ./myscript 0<&- &>/dev/null &
and even ./myscript.sh &
All of these return some 4-digit number, which, I guess, should be PID of the started process but when I launch lxtask there are no processes with this PID, even if I tick "view all processes". And, of course, it doesn't work!
