Touchpad-indicator settings do not affect touchpad Dell-XPS 933

[Chris Briggs]

Regardless of any settings I choose within touchpad-indicator they do not affect my touchpad. Ubuntu 14.04 on Dell-XPS-12 933. touchpad

works when "disabled"
scrolling options do not work

Used xinput -list to find device id

Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ ATML1000:00 03EB:842F id=12 [slave pointer (2)]
⎜ ↳ DLL05E3:01 06CB:2734 id=13 [slave pointer (2)]
⎜ ↳ SynPS/2 Synaptics TouchPad id=15 [slave pointer (2)]

xinput set-prop 15 "Device Enabled" 0 has no effect.
(USING id=13) does disable though

 "touchpad-indicator" seems to not use the "correct" device ID?

Seem to be same on my DELL XPS 13. touchpad-indicator do not affect my touchpad.

xinput -list :

⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ Logitech USB Laser Mouse id=10 [slave pointer (2)]
⎜ ↳ CyPS/2 Cypress Trackpad id=12 [slave pointer (2)]

But for me i can do :

xinput set-prop 12 "Device Enabled" 0

or

xinput set-prop 12 "Device Enabled" 1

to enable/disable manually my touchpad.

For my config, uname -a :

Linux JO-XPS13-L322X 3.13.0-44-generic #73-Ubuntu SMP Tue Dec 16 00:22:43 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

thanks for your help

I can confirm that the touchpad-indicator does not affect the touchpad of the new Dell XPS 13 running Ubuntu MATE 64 bit.

Linux 3.19.0-16-generic #16-Ubuntu SMP x86_64 x86_64 x86_64 GNU/Linux

In order to disable the touchpad, I have to do

xinput disable 13
AND
xinput disable 15.

Disabling just one of them doesn't cut it. Maybe that is why the touchpad-indicator doesn't work.

To correct myself: It is not always necessary to disable two devices when I do it manually.

With the New XPS 13 (Dell) an "unknown" device whose descriptor starts with "DLL0665:01" must be deactivated. Simply deactivating the "SynPS/2 Synaptics Touchpad" doesn't seem to achieve anything.

The id-numbers are slightly different after each start, so a very simple script is not going to cut it.
