    Holy necro Batman, you dug out a 5-year old thread just to post that?

    That said, developers who cannot get this right in 2014 should be driven out of the game market. This should have been a non-issue since the introduction of libXi (half a decade ago), and SDL2 now.

    Oops, right, 5 years, not 3.

    But as it's still the exact same issue, why not?

    Of course it should be a non-issue. With SDL2 there's even this very nice scaling of "fullscreen" applications with lesser resolution to the actual resolution that never changes the actual display resolution. This is how it should have been done years ago.

    It's this obsession over this one thing, altering the configuration the user has chosen for his display, that I don't get at all.

    I had played The book of Unwritten Tales on my laptop display a bit after I set the resolution to 1920x1080.

    Now I have connected an external display and started this game again. Can anyone guess what happened?

    The external display kept at 1920x1080 while the game started on the laptop screen AND CHANGED THE FUCKING RESOLUTION TO 1024x768. WHY

    Also I received one of those

    I realize that this probably comes from my drivers being git snapshots, but there is xf86CrtcSetModeTransform in the stacktrace so it still may be related.

    Since this thread has been resurrected...

    Found this problem in 0AD, too. Had volume turned down for background music (stopped before starting the game) but media shortcuts wouldn't work in game, nor would alt+tab. Related ticket:

    Few days ago I did it in Supertuxkart - run game using window manager fullscreen.

    It's not so easy like some people say. There were some issues. For example Gnome sometimes creates fullscreen window which is smaller than display. Actually it creates fullscreen window, but it says that it's smaller ;p And for example on Unity I can't open window as not-resizable because in such case it's opened in windowed mode - also I dunno why.

    I tested it on three desktop environments. And how many window managers we have on linux? Twenty? Or more?

    It's really much easier to use three commands:
    XSetInputFocus(display, window, RevertToParent, CurrentTime);
    XGrabKeyboard(display, window, True, GrabModeAsync, GrabModeAsync, CurrentTime);
    XGrabPointer(display, window, True, ButtonPressMask, GrabModeAsync, GrabModeAsync, window, None, CurrentTime);

    and to be sure that everything works properly.

    Even in Half-life 2 - it's really easy to disable fullscreen using window manager (flag + F or other shortcut) and resize it. In such case game will crash or will draw some strange things ;p
