touchpad disabled even when mouse is not plugged in

Postby adhefe » Feb 10th, '20, 02:30

I usually set touchpad to be disabled when mouse is plugged in. It has worked fine until some recent package update.

Today, the system 'sees' a mouse when no mouse is plugged in and disables touchpad. I then end up with no mouse and no touchpad.
The workaround is CTRL+ALT+F2, and editing .config/touchpadrc so that the line

DisableWhenMousePluggedIn=true

changes to,

DisableWhenMousePluggedIn=false

and then, back to CTRL+ALT+F1 and CTRL+ALT+DEL to logout and login again.

Is there something better to do? Anybody else has this problem?

Thanks

As a complement, below is the diff from dmesg without and with a mouse plugged in. The dmesg sees a mouse only when it is actually plugged in. Why would my KDE session disable touchpad then?

Can you share the output of xinput list with and without your mouse plugged in ? Also, does your display maybe have touchscreen support ?

My display has not touchscreen support ...

This is the content with mouse plugged in:

Code: Select all
⎡ Virtual core pointer                          id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ USB OPTICAL MOUSE                         id=12   [slave  pointer  (2)]
⎜   ↳ UNIW0001:00 093A:0003 Mouse               id=14   [slave  pointer  (2)]
⎜   ↳ UNIW0001:00 093A:0003 Touchpad            id=13   [slave  pointer  (2)]
⎣ Virtual core keyboard                         id=3    [master keyboard (2)]
    ↳ Virtual core XTEST keyboard               id=5    [slave  keyboard (3)]
    ↳ Power Button                              id=6    [slave  keyboard (3)]
    ↳ Video Bus                                 id=7    [slave  keyboard (3)]
    ↳ Video Bus                                 id=8    [slave  keyboard (3)]
    ↳ Power Button                              id=9    [slave  keyboard (3)]
    ↳ Sleep Button                              id=10   [slave  keyboard (3)]
    ↳ HD Webcam: HD Webcam                      id=11   [slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard              id=15   [slave  keyboard (3)]


And this is the content of xinput list without the mouse plugged in:

Code: Select all
⎡ Virtual core pointer                          id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ UNIW0001:00 093A:0003 Mouse               id=14   [slave  pointer  (2)]
⎜   ↳ UNIW0001:00 093A:0003 Touchpad            id=13   [slave  pointer  (2)]
⎣ Virtual core keyboard                         id=3    [master keyboard (2)]
    ↳ Virtual core XTEST keyboard               id=5    [slave  keyboard (3)]
    ↳ Power Button                              id=6    [slave  keyboard (3)]
    ↳ Video Bus                                 id=7    [slave  keyboard (3)]
    ↳ Video Bus                                 id=8    [slave  keyboard (3)]
    ↳ Power Button                              id=9    [slave  keyboard (3)]
    ↳ Sleep Button                              id=10   [slave  keyboard (3)]
    ↳ HD Webcam: HD Webcam                      id=11   [slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard              id=15   [slave  keyboard (3)]


The only difference I see is the line about the optical mouse.
Would it be possible that line about UNIW0001:00 093A:0003 Mouse is the source of this problem? Would it be that this was not there when the system did not say a mouse is plugged when there is no mouse at all, I mean, a few updates ago?

OBS: I had to install xinput (wasn't installed) to do this.

Thanks in advance

I don't know what devices your system saw a few updates ago ... I've tried to give you some hints on what the problem might be.

It could be different behaviour by the touchpad itself, have a look at e.g. https://ubuntu-mate.community/t/mouse-i ... ound/19844

Re: touchpad disabled even when mouse is not plugged in

Today I have mageia 8 and now touchpad gets unabled whenever I plug a mouse. OK. But today I have problems with the use of mouse and would like to turn this functionality off so that I could use the touchpad even when my mouse is plugged in.
It seems this option is no longer found in systemsettings. This used to be in
systemsettings=>hardware=>input devices=>touchpad but is no longer there. Where it is found in the new KDE of Mageia 8?

Thanks a lot.

This is the correct place. It's here on three different Mga8 Plasma machines.

It has been a while but I think that page changes depending on if you are synaptics or libinput.

What if I install the x11-xorg synapatics package? Incompatibilities with the libinput packages? Should I remove libinput? Will systemsettings5 change so as to show up the option to keep touchpad and mouse simultaneously?

Thanks

No incompatibilitys. The synapatics package provides the requested features.

To be clear: it's synaptics.
