    /* on Linux, SDL may use fbcon|directfb|svgalib when run without

     * accessible $DISPLAY to open X11 window.  This is often the case

     * when qemu is run using sudo.  But in this case, and when actually

     * run in X11 environment, SDL fights with X11 for the video card,

     * making current display unavailable, often until reboot.

     * So make x11 the default SDL video driver if this variable is unset.

     * This is a bit hackish but saves us from bigger problem.

     * Maybe it's a good idea to fix this in SDL instead.
