Factorio Forums

Hello there,

I noticed a very small bug that's just a bit annoying sometimes: I'm on Ubuntu (14.04 but I don't think it really matters) and I noticed that everytime I switch desktop while playing and come back to Factorio, the CTRL key is locked and I do all kind of stupid things in-game before realizing it. To switch desktop, I need to press CTRL+ALT+LEFT/RIGHT, and my guess is that, since the game never gets a "CTRL unpressed" signal, it somehow thinks I'm still pressing that key when I come back. Indeed: just pressing the key again resets the thing and fixes the problem.
I don't really know if you can do anything about it? It could be some problem in the libraries you're using, and anyway it's not such a big deal, it's just annoying.

Have a nice day, I love your game!

Did you try whether that happens with other similar/allegro applications as well?
Could even be a bug in some ubuntu component

Well I've played multiple games on Ubuntu (the last ones were Binding of Isaac, Terraria, Starbound, and of course Factorio) and only with this game has the problem shown up.
