Alt-Tab not working at all in Linux #375

Open MarkJeronimus opened 2 years ago

MarkJeronimus commented 2 years ago

I cannot alt-tab out of the game as long as the game is set to full-screen. This is a deal-breaker for me as it would mean I'd have to either exit or go into settings and toggle full-screen, every time I want to do something else like type something in discord.

I compiled 26um (from the release section) and f5ba5a39ad596af681ed3102fed5f28cc685089c, and both seem to suffer from this. It doesn't matter if I use 16bit, 32bit or OpenGL mode.

I don't know if it's a problem specific to my PC (as I see no one else complaining about this) because I don't have a second Linux PC. Please assist me, and yourself, in tracing this problem to the root cause. I already set up a working vscode project.

[edit] Added logs. I hope it's not too spammy.

I'm using Ubuntu 18.04 with Unity on XOrg.

Are you using "exclusive fullscreen" mode or are you running this in "desktop fullscreen" mode?

MarkJeronimus commented 2 years ago

desktop fullscreen

fabiangreffrath commented 2 years ago

Then... this shoudn't happen. Do you happen to use Wayland instead of X11 or some exotic (tiling?) window manager?

MarkJeronimus commented 2 years ago

Xorg as stated in the OP.

Aallright, searching for "desktop fullscreen" lead me to i_video.c, in which I started poking around.

I'm not too familiar with SDL2, bit this "hack" seems to work for me and I haven't yet found any side-effects:

      // Prevent executing action on Alt-Tab
      if (Event->key.keysym.sym == SDLK_TAB)
      {
        DeactivateMouse(); // Added (line 262)
        break;
      }
fabiangreffrath commented 2 years ago

Ah, cool! I wonder why SDL eats Alt-Tab at all.

MarkJeronimus commented 2 years ago

Adding SDL_SetRelativeMouseMode(SDL_TRUE); right after DeactivateMouse and stepping over it with the debugger, causes alt-tab to be eaten again, but I can still do everything else in vscode with the keyboard.

fabiangreffrath commented 2 years ago

Sorry, but I just checked with my Debian testing/unstable system and could not reproduce this.
