I have KSP installed on a Linux machine (Manjaro KDE)
Freshly installed, no mods, also no modified settings, everything has the default value.
When i try to launch any rocket, the space bar does noc activate the stage (it's not lack of electric power).
If i got to the input settings screen, click on the button to bind a key to the stage activation, and press space, it shows me "None" instead of space, so it looks like the game is not recognizing the key properly, as you can see in this video:

If anyone know how to fix this, will give a free ride to minmus (no return guarantee)
Never noticed that section before, looks like that was the problem indeed. Tks
