SDL has some checks in the code to make sure that you are the owner of
the current console before it'll start up, so without removing those
checks it won't work. Check out the SVGA_available function in
SDL's src/video/svga/SDL_svgavideo.c to fix it.
Here's a snippet:
static int SVGA_Available(void)
{
/* Check to see if we are root and stdin is a virtual console */
int console;
[...]
return(((svgalib2 != -1) || (geteuid() == 0)) && (console >= 0));
}
So if you remove the last part of that return function, it should do
what you want:
return((svgalib2 != -1) || (geteuid() == 0));
