Florian Forster to sdl
in SDL 1.3 (revision 5508 from SVN), the method used to calculate the
bits per pixel from a “int format” differ between “SDL_ListModes” (which
always uses the “SDL_BITSPERPIXEL” macro) and “SDL_PixelFormatEnumTo-
Masks” (which uses either “SDL_BITSPERPIXEL” or “SDL_BYTESPERPIXEL * 8”,
depending on the value of “SDL_BYTESPERPIXEL”).
Because the values are later compared in “SDL_ListModes” this may lead
to some valid video modes not being returned. In my case the only mode
returned by “SDL_GetNumDisplayModes” was dismissed and NULL was
returned. (This led to the calling application sticking its head in the
sand.)
The attached patch copies the method used within “SDL_PixelFormatEnumTo-
Masks” to “SDL_ListModes”. This solved the problem for me though I don't
fully understand the method used by “SDL_PixelFormatEnumToMasks”.

SDL 1.3 with open pandora console support ( http://openpandora.org/ ) ===================================================================== - A pandora specific video driver was writed to allow SDL 1.3 with OpenGL ES support to work on the pandora under the framebuffer. This driver do not have input support for now, so if you use it you will have to add your own control code. The video driver name is "pandora" so if you have problem running it from the framebuffer, try to set the following variable before starting your application : "export SDL_VIDEODRIVER=pandora" - OpenGL ES support was added to the x11 driver, so it's working like the normal x11 driver one with OpenGLX support, with SDL input event's etc..
