In the What can you do with a Thinkpad T430s running Xubuntu in 2022 article I mentioned that I was planning on using my T430s for gamedev using the Godot 3 game engine. One issue with running both Godot and Unity under Xubuntu is that both make use of the Alt key. Unfortunately so does Xubuntu, which leads to unexpected behaviour if you try to use the Alt key while in Godot or Unity.
To fix this problem in Xubuntu 20.04 or 22.04:
- Press CTRL + Esc to open the whisker menu
- Type Window Manager Tweaks and click on the Window Manager Tweaks program
- Click on the Accessibility tab
- Change Key used to grab Windows from Alt to another value (that value should be a key that isn’t already being used by the Keyboard bindings program). If you don’t need this Accessibility setting you can click none, but if you do make sure you check the keyboard program first for a non-conflicting key.
Alt in Godot lets you stretch things like sprites and collision boxes.
