Udev rule to disable touchpad when usbmouse is used [solved]

Hello guys,

I tried the udev-rule from the wiki to disable/enable touchpad when my usbmouse is plugged/unplugged.

Here is the rule:

#/etc/udev/rules.d/01-touchpad.rules  
ACTION=="add", SUBSYSTEM=="input", ENV{ID_CLASS}="mouse", RUN+="/usr/bin/synclient TouchpadOff=1"
ACTION=="remove", SUBSYSTEM=="input", ENV{ID_CLASS}="mouse", RUN+="/usr/bin/synclient TouchpadOff=0"

The problem is that the status of my touchpad won't change when I plug/unplug my mouse. It has to be a problem with the rule because manually the synclient command works without any problem.

Here is the relevant output of lsusb:

Bus 007 Device 012: ID 046d:c00c Logitech, Inc. Optical Wheel Mouse

Thank you. smile

Re: Udev rule to disable touchpad when usbmouse is used [solved]

I _know_ its not what you are looking for - but here's another way ...
"rmmod psmouse" in /etc/rc.local (seeing that I almost always use a usb-mouse)
If I dont have a mouse, "modprobe psmouse" on the command line (I always boot up to the cli - then startx) - thus I always have some kind of pointing device available by the time X comes up

I must admit I don't like playing around with 'rules' - rmmod/modprobe works fine for me.

Re: Udev rule to disable touchpad when usbmouse is used [solved]

Hello perbh,

thanks for your solution but I use udev very often and would prefer such a rule.

Any other suggestions I could try?

Re: Udev rule to disable touchpad when usbmouse is used [solved]

SUBSYSTEMS=="usb", DRIVERS=="usb", ATTRS{manufacturer}=="Logitech", ATTRS{product}=="USB Receiver", ACTION=="add", RUN+="/usr/bin/touchpadtoggle 1"
SUBSYSTEMS=="usb", DRIVERS=="usb", ATTRS{manufacturer}=="Logitech", ATTRS{product}=="USB Receiver", ACTION=="remove", RUN+="/usr/bin/touchpadtoggle 0"

where touchpadtoggle is

#!/bin/bash
export DISPLAY=":0"
/usr/bin/synclient touchpadoff=$1

Hello Coacher,

I tried this but it's still not working. sad

What else could I try?

The script itself is working flawlessly.

Might not be really what you're looking for (but I'll post it anyway). Thunar and thunar-volman can be setup to run a program/script when a mouse is inserted. Give it a try!

Re: Udev rule to disable touchpad when usbmouse is used [solved]

show result of

ls -l /usr/bin/touchpadtoggle

and just to be sure. You've modified that udev-rule to fit your mouse, havent you?

Re: Udev rule to disable touchpad when usbmouse is used [solved]

[root@thinkpad]# ls -l /usr/bin/touchpadtoggle
-rwxr-xr-x 1 root root 66 11. Mär 13:31 /usr/bin/touchpadtoggle

Yeah I adapted it the following:

SUBSYSTEMS=="usb", DRIVERS=="usb", ATTRS{manufacturer}=="Logitech", ATTRS{product}=="Inc. Optical Wheel Mouse", ACTION=="add", RUN+="/usr/bin/touchpadtoggle 1"
SUBSYSTEMS=="usb", DRIVERS=="usb", ATTRS{manufacturer}=="Logitech", ATTRS{product}=="Inc. Optical Wheel Mouse", ACTION=="remove", RUN+="/usr/bin/touchpadtoggle 0"

I think it should be right?

Re: Udev rule to disable touchpad when usbmouse is used [solved]

Well, seems that script is executable and runs fine, as you said, so the only option is some mistakes in udev-rules.
Try running

udevadm monitor --property > ./log

and plug in or out your mouse.
Then open ./log file, you'll see a bunch of events there. Your udev-rule will work if it satisfies any of this. So choose one and modify your rule to fit it

Re: Udev rule to disable touchpad when usbmouse is used [solved]

Hello Coacher,

I did what you said but have no idea what to do with that logfile. I'll better post it here. Perhaps you could help me again.

monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
KERNEL - the kernel uevent

Re: Udev rule to disable touchpad when usbmouse is used [solved]

I have something fairly similar set up (which also involved a fair amount of trouble to get working).   Maybe it will help.

ACTION=="add", SUBSYSTEM=="usb", ATTRS{idVendor}=="<insert vendor id>", ATTRS{idProduct}=="<insert product id>", ENV{REMOVE_CMD}="/usr/bin/touchpadtoggle 0", RUN+="/usr/bin/touchpadtoggle 1"

I've modified it to suit your case.  I use the product and vendor IDs of the device to identify it, though you should be able to use whichever attributes you please.

Re: Udev rule to disable touchpad when usbmouse is used [solved]

The vendor and product IDs should be 4 digit hex -- I don't think any other value is valid.  Otherwise, that looks fine.

ACTION=="add", SUBSYSTEM=="usb", ATTRS{idVendor}=="046d", ATTRS{idProduct}=="c00c", ENV{REMOVE_CMD}="/usr/bin/touchpadtoggle 0", RUN+="/usr/bin/touchpadtoggle 1"

Re: Udev rule to disable touchpad when usbmouse is used [solved]

chpln you're great. It works flawlessly now. smile

Thank you man!

And just to know it, what's the sense of creating this touchpadtoggle script as I can directly use /usr/bin/synclient?

EDIT:

Just tested it without the script and it isn't working anymore. So the export DISPLAY=":0" from script seems to be necessary. But what is it for?

And is it normal that I get a error message during boot called "can not open display"?

Good that you handled with udev rule.
It is not work because the synclient can and do selective touchpad on/off in multiple instances of X.
When you run it from X terminal emulator it knows that it should toogle touchpad only for current server because of DISPLAY variable is set.
When running this script via udev which runs with root user environment there is no X running there, so DISPLAY variable is not set(until you run X from root). That's why exporting it needed.
And talking about boot message as you should understand by now, there is no X running at all on DISPLAY=0: or somewhere else, so synclient's connection to it fails.
P.S. there could be add some workaround like this

#!/bin/bash
if [ "$(pidof X)" ]; then
export DISPLAY=":0"
/usr/bin/synclient touchpadoff=$1
fi

.please note it is very stupid solution which toggles touchpad on DISPLAY 0: even if no X presented there

well here is working but REALLY ugly script which turns off touchpad for all running X servers. Its midnight here and I couldnt produce anything smarter till morning.
P.S. very bad script, but works)

#!/bin/bash
totalX=`pidof X | xargs ps p | grep X | awk '{print $6}' | wc -l`
Xwithnum=`pidof X | xargs ps p | grep X | awk '{print $6}' | grep [0-9] | wc -l`
str=`pidof X | xargs ps p | grep X | awk '{print $6}' | grep [0-9]`
diff=`expr $totalX - $Xwithnum`
if [ "$diff" = "1" ]; then
    #echo "toggling on 0"
    export DISPLAY=":0"
    /usr/bin/synclient touchpadoff=$1
fi
while [ $Xwithnum -gt 0 ]
do
    #echo "toggling on $Xwithnum"
    Xwithnum=`expr $Xwithnum + 1`
    disp=`echo $str | cut -d':' -f$Xwithnum`
    Xwithnum=`expr $Xwithnum - 1`
    export DISPLAY=":$disp"
    /usr/bin/synclient touchpadoff=$1
    Xwithnum=`expr $Xwithnum - 1`
done

Re: Udev rule to disable touchpad when usbmouse is used [solved]

Hello Coacher,

thanks for your scripts. I tried the last one but the udev rule still doesn't work at boot.

Is there any way to change the script that the rule will work directly after startup instead of first plugging in the mouse again?

Re: Udev rule to disable touchpad when usbmouse is used [solved]

Hi. Here is script that working on my machine, but it wasnt tested during boot. So, try it and let me know if it works.
P.S. delete all lines with 'echo' for silent-mode without any messages

#!/bin/bash
# Script to toggle on/off touchpad on all local running X-servers at the same time
# Not tested for network usage

if [ -f /var/run/touchpadtoggle.pid ]
then
    echo "Already have another task..."
    if [ `cat /var/run/touchpadtoggle.task` = "$1" ]
    then 
        echo "Already have same task. Exiting."
        exit
    else
        echo "Already have opposite task. Killing it and exiting." 
        cat /var/run/touchpadtoggle.pid | xargs kill -15
        rm /var/run/touchpadtoggle.task
        rm /var/run/touchpadtoggle.pid
        exit
    fi      
fi
toggling() {
echo "Checking for running X servers..."
if [ `pidof X | tr " " "\n" | wc -l` != "0" ]
then 
    echo "Have running X servers."
    save=$DISPLAY

    diff=`expr $totalX - $Xwithnum`
    if [ "$diff" = "1" ]
    then
        echo "Toggling on :0"
        #export DISPLAY=":0"
        #/usr/bin/synclient touchpadoff=$1
    fi
    Xwithnum=`expr $Xwithnum + 1`
    while [ $Xwithnum -gt 1 ]
    do
        disp=`echo $dispNums | cut -d':' -f$Xwithnum`
        echo "Toggling on :$disp"
        export DISPLAY=":$disp"
        /usr/bin/synclient touchpadoff=$1
        Xwithnum=`expr $Xwithnum - 1`
    done
    export DISPLAY="$save"
    if [ -f /var/run/touchpadtoggle.pid ]
    then 
        rm /var/run/touchpadtoggle.pid
    fi
    if [ -f /var/run/touchpadtoggle.task ]
    then 
        rm /var/run/touchpadtoggle.task

Re: Udev rule to disable touchpad when usbmouse is used [solved]

Hello Coacher,

something isn't really working. It hangs up on boot at

Waiting for Udev uevents to be proceeded

I am then just able to quit it via Ctrl+C. Otherwise he would not continue.

Re: Udev rule to disable touchpad when usbmouse is used [solved]

Hm. The problem is that I dont have such problems on boot even with old version of script and cant test it.
Ah! I guess I understood where is the problem!
I'll add fix today evening:)

Re: Udev rule to disable touchpad when usbmouse is used [solved]

Haha. Shame to me. I forgot how I fixed similar problem myself. Just adding

if /usr/sbin/lsusb --verbose 2>&1 | grep --quiet "Mouse"; then
        /usr/bin/synclient TouchPadOff="1"
fi

to .xinitrc just before line 'exec yourDEname'
And when run you srever with startx everything should work. However, I'll try to finish working on this script.

Re: Udev rule to disable touchpad when usbmouse is used [solved]

Hello Coacher,

so when I use this last approach in .xinitrc then there's no need of the touchpadtoggle script?

Re: Udev rule to disable touchpad when usbmouse is used [solved]

This addition to .xinitrc will only turn on/off touchpad on X start, though you still need that touchpad toggle scipt which will handle mouse plugin/out the rest of the time.

Re: Udev rule to disable touchpad when usbmouse is used [solved]

Yeah it's working like a charme. smile

The only thing that still occurs is the cannot open display "" message while starting crond at boot. Any suggestion how I could deactivate that?

Perhaps with a simple > /dev/null?
