Keyboard stop working after a while on Linux X11

[fernandot]

Hi,

I'm developing a multiplataform application that runs on windows and linux. i don't have any problem running it on windows, but when a run it on linux using Non-exclusive input my keyoard stops working after a while.

It only happens when i set x11_keyboard_grab as "false"

Does anyone knows what could cause that?

My input Manager code:

Code: Select all

#include "InputManager.h"
#include <QForeachContainer>

#if defined( __WIN32__ )
LRESULT CALLBACK ChildWndProc(HWND hwnd,UINT Message,WPARAM wParam,LPARAM lParam)
{
switch (Message)
    {
    case WM_SETCURSOR:
        {
        static HCURSOR Cursor = LoadCursorFromFile(L"aliendance.ani");
        SetCursor(Cursor);
        return TRUE;
        }
    }
    return TRUE;
}
#endif

I just ran into this same problem (and spent more time than I want to admit tracking it down). My keyboard would stop responding after about 20 seconds (even if nothing happening in game/ogre). I could work around it by setting x11_keyboard_grab to true. But that wasn't an acceptable fix to me.

The problem went away when I switched back to OIS-1.2.0 (it was OIS-1.3 that didn't work for me in Gentoo Linux). I'm assuming it is a bug. There seems to be existing reports of it. Hopefully it will be solved going forward.

[xelfe]

I bump this post. I have the same problem on linux. There's any way to fix this without downgrade OIS ?

[underworldguardian]

I bump this post as well. If I set

Code: Select all

 pl.insert(std::make_pair(std::string("x11_keyboard_grab"),std::string("false")));

the Keyboard stops responding after 31 seconds. I used a program internal timer to find it out.

After 31 seconds, none of the keyboard events get through to the keyPressed(...) and keyReleased(...) methods. I use buffered input with OIS 1.3.0 Anybody knows a fix for that? It seems that we have to downgrade, because OIS development seems to be quite dead.
