its in the first sentence. let me rephrase: the (windows) guest can select some
screen resolution which SDL cannot
provide. what happens is that qemu quits without giving the quest a chance to
shut down. thats like having a monitor
that crashes windows when it doesnt support the video mode.

Title:
unsupported screen resolution crashes sdl-qemu
Status in QEMU:
New
Bug description:
if the (windows) guest sets a screen resolution that the SDL backend does not
support,
qemu does an exit(1).
with this fix, the the resolution is still wrong (only part of the desktop is
displayed),
but qemu keeps running and the guest can auto-revert the video mode:
ui/sdl.c:do_sdl_resize()
SDL_Surface * tmp_screen;
tmp_screen = SDL_SetVideoMode(width, height, bpp, flags);
if (!tmp_screen) {
// fprintf(stderr, "Could not open SDL display (%dx%dx%d): %s\n", width,
// height, bpp, SDL_GetError());
// exit(1);
} else {
real_screen = tmp_screen;
}
