Issue/Bug Description: Setting touchpad's send-event with Dconf Editor to 'Disabled-on-external-mouse' disables the touchpad completely, even when mouse is disconnected.

Steps to reproduce (if you know):

Expected behavior: Touchpad should be disabled when external mouse is connected and should be enabled automatically when disconnecting the mouse.

Other Notes: Lenovo Y540

I tried to recreate this issue on 3 different computers with 2 different mice and the setting behaved just as expected.

Have you tried rebooting after changing the setting?

pollaloca commented 4 years ago

Yes. I have rebooted the laptop several times since I found the problem. It happens with both bluetooth and USB mice. And if I go to settings and activate the touchpad (while mouse connected), it doesn't work.

I notice that if I activate the touchpad via GNOME Settings when the mouse is connected, the dconf setting changes from disabled-on-external-mouse to enabled.

This all seems to be working as I would expect on the machines/mice I have tested on.

Perhaps you have some other dconf settings changed that are causing additional issues? Perhaps you could also try this on a fresh install/live image/recovery partition to see if that may in fact be the case.

I've just tried with a live USB and it appears to be working correctly. Not sure what can be interfering with this.

I've also notice that when booting up, in the login manager the touchpad works even if the mouse is connected

Potentially resetting dconf/gsettings may do the trick for you (dconf reset -f /). A word of caution however, it will revert this https://github.com/pop-os/default-settings/blob/master/usr/bin/pop-app-folders which you can just run again and should be back to defaults.

All of the Pop!_OS defaults are set here: https://github.com/pop-os/default-settings and https://github.com/pop-os/session

So, I've decided to follow the nuke&pave path but I still have the same problem.

These are the steps that I've followed: 1.- Clean install of Pop_OS 19.10 2.- sudo apt update 3.- sudo apt upgrade 3.- reboot 4.- sudo apt install dconf-editor 5.- Setted Touchpad's 'send-event' to 'disable-on-external-mouse' 6.- reboot 7.- Disconnected external mouse 8.- Touchpad not working

Also, for some reason, Lenovo logo appears after loging in: 1.- Login manager 2.- Lenovo logo screen appears 3.- black screen 4.- Lenovo logo screen appears again 5.- desktop appears.

Now I've done: 1.- dconf reset -f / 2.- reboot 3.- disconnect mouse 4.- Touchpad not working

After tinkering a little bit, it appears that the problem comes from the bluetooth: 1.- New fresh clean install 2.- apt update 3.- apt upgrade 4.- Reboot 5.- Install dconf-editor 6.- Set Touchpad's send-event to disable-on-external-mouse 7.- Plug USB mouse: mouse works / touchpad is disabled 8.- Unplug USB mouse: mouse doesn't work / touchpad works 9.- Enable bluetooth (from settings) 10.- Pair with bluetooth mouse: mouse works / touchpad is disabled 11.- Turn off bluetooth mouse: mouse doesn't work / touchpad is disabled 12.- Plug USB mouse: mouse works / touchpad is disabled 13.- Unplug USB mouse: mouse doesn't work / touchpad is disabled 14.- Reboot 15.- Plug USB mouse: mouse works / touchpad is disabled 16.- Unplug USB mouse: mouse doesn't work / touchpad works
