cariboublocker for GNOME Shell 3.36 (and above)

Available at: https://extensions.gnome.org/extension/3222/block-caribou-36/

Based on https://github.com/keringar/cariboublocker.

Change some naming to be compatible with GNOME Shell 3.36.

There are some naming changes in GNOME Shell, so the original project by keringar no longer works on some GNOME Shell versions (For me, it works on Fedora 31 with gnome-shell-3.34.5 and Xorg, but not on Fedora 32 with gnome-shell-3.36.3 and Xorg).

Install

Install this extension using one of the following ways. If your GNOME Shell version is higher than this extension is configured to support, you can still try this extension following Installing on high GNOME Shell version below.

Update for GNOME Shell 44 (Fedora 38): it looks like you need to restart GNOME Shell after enabling or disabling this extension.

Way 1: use extensions.gnome.org

This extension is available at the official GNOME Shell Extensions website: https://extensions.gnome.org/extension/3222/block-caribou-36/

Way 2: download zip

Go to Releases, and choose the zip file corresponding to your gnome-shell version. Then gnome-extensions install <your-gnome-shell-version>.zip.

Installing on high GNOME Shell version

This extension is likely to work for a high GNOME Shell version, if GNOME Shell's keyboard.js is not changed. This extension specifies a number of supported GNOME Shell versions in metadata.json. If your GNOME Shell version is not in this list, you may not be able to install this extension.

There are a few possible solutions:

In dconf, set disable-extension-version-validation (in /org/gnome/shell/) to True. See https://gjs.guide/extensions/overview/anatomy.html#shell-version.
Download this extension as a zip file, from either extensions.gnome.org or GitHub. Then add your GNOME Shell version number to metadata.json in the list specified by "shell-version".
Wait for the extension maintainer (currently lxylxy123456) to update the extension. Maybe notifying the maintainer on extensions.gnome.org or GitHub can help.

Change Log

3.36.3

Replace Keyboard with KeyboardManager in extensions.js.

40.0

Simply change "shell-version" in metadata.json to 40.0. For some reason the version string "3.36.3" still works on Fedora 33's gnome-shell-3.38.

40

Update shell-version in metadata.json

41

Update shell-version in metadata.json

42

Update shell-version and description to be more comprehensive

43

Update shell-version in metadata.json

44

Update shell-version in metadata.json

Relevant Code

See js/ui/keyboard.js. Here are links for some versions after 3.36:

The structure of code is:

var KeyboardManager = class KeyBoardManager {
    constructor() {
        ...
    }

    _lastDeviceIsTouchscreen() {

        if (!this._lastDevice)
            return false;

        let deviceType = this._lastDevice.get_device_type();
        return deviceType == Clutter.InputDeviceType.TOUCHSCREEN_DEVICE;
    }

    ...
}

This extension simply replaces _lastDeviceIsTouchscreen with a function that always returns false.

In GNOME Shell 3.34 and earlier, the class was named Keyboard instead of KeyboardManager. So keringar's extension no longer works after GNOME Shell 3.36.

Development Hints

Looking Glass is very helpful for debugging (saves my time installing an IDE etc).
