I do have many other GNOME extensions, but I've turned them all off, I rebooted, and still the same error. That error shows up in "Extensions" application > locate "Touchpad Indicator" > wheel next to it:

Touchpad Indicator has always been failing for me since I've installed it at least a year ago. My system is current Manjaro, GNOME version 3.36.1, X11.

• Operating System: Manjaro (current - Manjaro does not have a version, since it's a rolling release)

• Touchpad Indicator extension version: 35

• Gnome Shell version: GNOME Shell 3.36.1+31+ga6783692c-1 (the most recent that came with Manjaro, but the same problem exists for over a year)

• Display server: X11

• Switching method: GSetting or Xinput or Synclient - No idea. Can this be "gsettings-desktop-schemas 3.36.0-1"? Otherwise, if you need this, please elaborate.

• Installation source: extensions.gnome.org

• Input Devices (ie. output for cat /proc/bus/input/devices)

Thank you in advance.

Please try installing the xorg-xinput package on your system.

It seems that the extension fails when trying to log to the system journal. This should not be happening. Try changing global.log(LOG_PREFIX + message); to log(LOG_PREFIX + message); in lib.js file and see if that helps.

Hi Ashesh,

Thank you for Touchpad Indicator, and for a quick response. Confirming

• installing xorg-xinput fixed it - the extension worked immediately. However, I'm surprised that this package is needed, since (for me) it uses GSettings.
• changing global.log to log fixed the error and I can manage its all settings.

It would help the users if you put a note to README.md about installing xorg-xinput - if it will stay as mandatory.

[askmrsinh]

Technically, the extension should work even without xinput command being present. However, the functionality would be limited.

There was an enhancement for pre-checking xinput (issue #48). I think the second edit (ie. changing global.log to log) was necessary in your case for the extension to work.
It would be great if you could verify by uninstalling the xorg-xinput package and restarting the gnome shell. In that case I can make the required changes permanent.

[peter-kehl]

Thank you for the feedback and the direction. I've uninstalled xorg-xinput, re-logged in, but it failed. Logs:

And an error in Touchpad Indicator's settings:
