Ubuntu 23.10 Tiling Assistant stops working when Alt is set as the modifier button.

Description: Ubuntu 23.10
Release: 23.10

Package name: gnome-shell-extension-tiling-assistant package (Ubuntu Tiling Assistant)
Package version: 44

---

In Ubuntu 23.10, changing the window-move mouse button modifier from Super to Alt with e.g.

$ gsettings set org.gnome.desktop.wm.preferences mouse-button-modifier '<Alt>'

and then trying to hold Alt while dragging the window from its center (or anything but the title bar), to edge/corner, does not perform tiling.

I also made a video that uses Gnome Tweaks to adjust the modifier and to demo the bug:

Reverting the changes with

$ gsettings set org.gnome.desktop.wm.preferences mouse-button-modifier '<Super>'

makes the tiling work with Super again.

I installed gnome-shell-extension-manager and had a look at the Ubuntu Tiling Assistant settings, but couldn't find one related to this.

I'm sure this is a bug since as per lines 50..55 of the source

/<email address hidden>/src/extension/moveHandler.js

also in the original repo:

https://github.com/Leleat/Tiling-Assistant/blob/main/tiling-assistant%40leleat-on-github/src/extension/moveHandler.js#L50

Using Alt is intended to be handled:

const altAsMod = wmPrefs.get_string('mouse-button-modifier') === '<Alt>';
if (altAsMod) {
    for (const s of [Settings.ADAPTIVE_TILING_MOD, Settings.FAVORITE_LAYOUT_MOD]) {
        const mod = Settings.getInt(s);
        if (mod === 1) // 1 -> Alt; see settings ui
            Settings.setInt(s, 3); // 3 -> Super; see settings ui

I opened an issue about this bug upstream on Dec. 4, 2023:

https://github.com/Leleat/Tiling-Assistant/issues/313

On Feb. 20, 2024, the author stated the following:

```FTR, (stock) Tiling Assistant checks if the Window Action Key is set to Alt and switches the Super and Alt activated grab mode modifiers. But that only happens during install/enable time of the extension. That means if you change the Window Action Key while Tiling Assistant is already enabled, there may be conflicts. I will extend the conflict check by monitoring changes to the gsetting.```

The bug fix was merged in https://github.com/Leleat/Tiling-Assistant/commit/e575676d7df6e3fd3a1701afa1d0db18b31000e3 on Feb. 27, 2024.

Thus, it should now be fixed by just using the latest plugin version from upstream.

The bug was fixed upstream in https://github.com/Leleat/Tiling-Assistant/commit/e575676d7df6e3fd3a1701afa1d0db18b31000e3 on Feb. 27, 2024, and isn't present in 24.04 LTS. Since 23.10 EoL is approaching, the way I see it, this bug is now resolved and the issue can be closed.
