Restore the windowed position and size when coming back from fullscreen.
Also fixed problem where Cocoa would move the windows in response to the fullscreen mode change.

Fixed bug 1145 (GL Context creation fails for OpenGL 3.2 + Alpha buffer with X11 BadMatch)

Matthias 2011-02-23 09:37:51 PST

Please view the attached source file. Using this minimal program (as attached),
it creates an OpenGL 2.0 context with a cleared color buffer. If I set the
OpenGL version to 3.2, the function SDL_GL_CreateContext fails (or more
specifically, glXMakeCurrent fails) with an X11 BadMatch error:


X Error of failed request: BadMatch (invalid parameter attributes)
Major opcode of failed request: 128 (GLX)
Minor opcode of failed request: 5 (X_GLXMakeCurrent)
Serial number of failed request: 153
Current serial number in output stream: 153


Also note that if I do not specify the alpha buffer size, the program works for
OpenGL 2.0 and OpenGL 3.2.

After some further analysis, I believe I have found the problem. The specific
issue is in:

SDL_x11opengl.c::X11_GL_CreateContext.

Note that for OpenGL 3.2 contexts, the GLXFBConfig to use is chosen as the best
match from glXChooseFBConfig. However, opengl attributes originally set with
SDL_GL_SetAttribute are not mapped to GLX attributes and then passed to the
glXChooseFBConfig function. According to the GLX 1.4 specification, if the
attributes are not specified, the function falls back to defaults (which, in
this particular case, prefer alpha channel size == 0).

For testing purposes, I modified the call to glXChooseFBConfig to look
something like this:


int glxAttribs[] =
{
GLX_RED_SIZE,8,
GLX_GREEN_SIZE,8,
GLX_BLUE_SIZE,8,
GLX_ALPHA_SIZE,8,
None
};

if (!glXChooseFBConfig ||
!(framebuffer_config = glXChooseFBConfig(display, DefaultScreen(display),
glxAttribs, &fbcount)))
{
...
}


The best match GLXFBConfig then supports 8 bit alpha channel. The program then
works as intended.


Hope this helps!

Patch for SDL_VIDEO_CENTERED & OpenGL bug

Stephen Anthony to SDL

Using SDL_VIDEO_CENTERED in Linux OpenGL mode issue an unwanted
ConfigureNotify event *after* the SDL screen has already been resized.
When going from a smaller to a larger screen, this event causes the mouse
tracking to be clamped at the *smaller* screen size, even though that
screen no longer exists.

The fix is to not issue a ConfigureNotify when the window is moved because
of the SDL_VIDEO_CENTERED environment variable. The included patch fixes
this bug. It seems the hints must be set before the window is moved.

nasm 2.09 compatibility

nasm-2.09 makes `elf' alias to `elf32', thus __OUTPUT_FORMAT__ macro
becomes `elf32' instead of `elf' (on x86). Unmatched macro value causes
omitting .note.GNU-stack marker and creates ELFs with executable stack.
This is unneeded and attracts security policies like SELinux.
