How to set the automatic disable touchpad after plugging in the external mouse?

Support
21

@cscs

Will other USB devices make my touchpad unavailable?

22

What? You’ve never used a Bluetooth mouse?

23

Nope. But I knew they existed. And my wife uses one.

I just never in my wildest dreams expected to ever interact with one here, on the forum. :wink:

Oh … ok … then we should use bluetooth or input subsystem…

KERNEL=="mouse*", SUBSYSTEM=="bluetooth*", ATTR{type}=="bluetooth", ACTION=="add", \
  RUN+="/usr/bin/xinput disable 'ALP001A:00 044E:121B Touchpad'"
KERNEL=="mouse*", SUBSYSTEM=="bluetooth*", ATTR{type}=="bluetooth", ACTION=="remove", \
  RUN+="/usr/bin/xinput enable 'ALP001A:00 044E:121B Touchpad'"

No, and not bluetooth either … it should just match for when a mouse is active.

25

Can USB and Bluetooth be configured at the same time?

26

Sure… either in the same file or separate ones.

27

@cscs Success!

You can add this method to the wiki for the convenience of other users

28

Glad it worked out… I think thats my first bluetooth udev rule :partying_face:

( my bluetooth rules all start with blacklist :smiling_imp: )

Restart the computer

It seems to have failed again

There should be no change to the device

How do I determine if a rule is in effect？

30 
xinput disable 'ALP001A:00 044E:121B Touchpad'

The touchpad button still works after the trackpad is disabled

31

Odd. Basically any rules in the proper locations should be loaded.
If you find the device location, like /sys/devices/platform/AMDI0010:01/i2c-1/i2c-ELAN2203:00/0018:04F3:309A.0002, then you could query things from it like

sudo udevadm test /sys/devices/platform/AMDI0010:01/i2c-1/i2c-ELAN2203:00/0018:04F3:309A.0002

Hm… I wonder if that ‘mouse’ with the same address might be the thing …

xinput disable 'ALP001A:00 044E:121B Mouse'
32 
 cd /sys/devices/platform/AMDI0010:01/i2c-1/                                                    
 ls                                                      
delete_device  device  firmware_node  name  new_device  power  subsystem  uevent  waiting_for_supplier
pwd                                              
/sys/devices/platform/AMDI0010:01/i2c-1

There seems to be something different

33

It doesn’t seem to work

34

I know … it was just an example … you would need to find your device.

Maybe you could find it with something like …

sudo udevadm trigger --verbose | grep -i 'ALP001A'
35

sudo udevadm test /sys/devices/platform/AMDI0011:00/i2c-2/i2c-ALP001A:00/0018:044E:121B.0001

This program is for debugging only, it does not run any program
specified by a RUN key. It may show incorrect results, because
some values may be different, or not available at a simulation run.
