udevadm monitor --property > ./log

produces

Re: [solved] udev rule to disable touchpad when mouse plugged in

No one familiar with udev? Really could need more tips for this. I even went through the article of how-to creating udev rules, but didn't succeed yet.
So, help is appreciated! 👁 wink

Thanks in advance.

Re: [solved] udev rule to disable touchpad when mouse plugged in

Okay, this is nowhere near optimal, and only tested with a bluetooth mouse, but here it goes:

ACTION=="add", SUBSYSTEM=="hid", ENV{HID_UNIQ}=="00:11:22:33:44:55", RUN+="/usr/local/bin/touchpad-disable"
ACTION=="remove", SUBSYSTEM=="hid", ENV{HID_UNIQ}=="00:11:22:33:44:55", RUN+="/usr/local/bin/touchpad-enable"

Here, 00:11:22:33:44:55 is the BDID of my mouse. This can certainly be adapted to USB mice. Now comes the tricky part: As synclient uses the xinput extension, you need to access the X server. For that, you need an xauth cookie, which the root user usually doesn't have.

#!/bin/bash

if [ "$(basename $0)" = "touchpad-enable" ]; then
 val=0
elif [ "$(basename $0)" = "touchpad-disable" ]; then
 val=1
else
 exit 1
fi

for f in /var/run/xauth/*; do
 if [ -e "${f}" ]; then
 XAUTHORITY="${f}" \
 DISPLAY=":$(basename "${f}" | cut -d- -f1 | cut -d: -f2)" \
 /usr/bin/synclient TouchpadOff=${val}
 fi
done

As far as I know, this will only work with kdm. kdm creates the file /var/run/xauth/A:$DISPLAY-$RANDOMCHARACTERS. From that filename, I parse $DISPLAY and use it as X authority database. This allows the script to access the X server and run synclient.

I suspect something similar is possible with other login manager. I don't know how to do it with startx at all. Still, I hope you get the idea and understand why your approach will fail.

Re: [solved] udev rule to disable touchpad when mouse plugged in

So if I add (according to https://wiki.archlinux.org/index.php/To … _detection) the following:

ENV{XAUTHORITY}="/home/domac/.Xauthority"

it should work, I guess. Let me try, I'll give feedback here.

Edit: Still no success with

$domac.vex cat /etc/udev/rules.d/01-touchpad.rules 
ACTION=="add", SUBSYSTEM=="usb", ENV{XAUTHORITY}="/home/domac/.Xauthority", ATTRS{idVendor}=="192f", ATTRS{idProduct}=="0616", ENV{REMOVE_CMD}="/usr/bin/synclient TouchpadOff=1", RUN+="/usr/bin/synclient TouchpadOff=0"

👁 sad

Re: [solved] udev rule to disable touchpad when mouse plugged in

Works now!

$domac.vex cat /etc/udev/rules.d/01-touchpad.rules 
ACTION=="add", SUBSYSTEM=="usb", ENV{XAUTHORITY}="/home/domac/.Xauthority", ENV{DISPLAY}=":0", ATTRS{idVendor}=="192f", ATTRS{idProduct}=="0616", ENV{REMOVE_CMD}="/usr/bin/synclient TouchpadOff=0", RUN+="/usr/bin/synclient TouchpadOff=1"

Thanks for the help!

Edit: More informations:

$domac.vex ls /etc/udev/rules.d/
total 4
-rw-r--r-- 1 root root 238 Aug 9 15:59 01-touchpad.rules
