Touchpad settings ignored/missing after update

English Hardware
1

Changing the /org/gnome/desktop/peripherals/touchpad settings in dconf have no effect. “gsettings get” agree with dconf but no effect.
In the new GNOME settings section mouse & touchpad there are no settings for touchpad input anymore only Mouse and General. The computer is a Macbook air (mid 2013).

Other dconf periferals settings work like: keyboard, displays. The touchpad works well in otherwise. (although it is hard to write on a laptop with large touchpad when tap-to-click is enabled causing constant accidental clicks)

I suspect the problem appeared when updating to GNOME 3.26 the other week at witch point I belive the settings where changed back to default.

I have run out of things to test… What can I have done wrong? Or is this a known issue / where should I report it?

Hi
So there are no setting options under System Settings -> Devices -> Mouse & Touchpad?

Are you running Wayland or X?

Only mouse and general settings, no touchpad settings

Are you running Wayland or X?

Wayland as it is the default in TW

Hi
OK, I have an older MacBook (2007) and in both Xwayland and X I see Touchpad settings, if plug a mouse in those settings appear as well.

As root user, what is the output for;


hwinfo --mouse

I guess that explains why I cant change the touchpad settings as the system thinks my touchpad is a mouse…

Yes that does appear to be the case. FWIW, the exact capabilities of the device can be examined using

sudo libinput-list-devices

As libinput is work in progress, a bug report may be needed to get this device handled properly.

The relevant (I hope) part of the output of libinput-list-devices:

Ok, I will try and put together a bug report

Actually, the output for the touchpad looks ok to me, and ‘Tap-to-ckick’ is disabled.

10

Yes, but still it is not actually disabled… This is all very weird.

Created a bug report. "]https://bugs.freedesktop.org/show_bug.cgi?id=103057)](https://bugs.freedesktop.org/show_bug.cgi?id=103057)

11

You have inadvertently added a bracket character to the URL. It should be

https://bugs.freedesktop.org/show_bug.cgi?id=103057

12

Yes, sorry, tried to make the link pretty but only made it pretty useless.

The latest bet is that the bug is not in libinput and my bug report there is now resolved as “not our bug”.

13

I wouldn’t be surprised. The output you posted here doesn’t suggest any issues with the touchpad device.

14

So the “solution” to this problem eventually consisted of me reinstalling Tumbleweed. After re-installation the settings worked again.

Still have no idea what caused it but at least it is working now.

Thank you all for your help.
