Also you need to set vga mode and color:
 #include <stdio.h>
 #include <stdlib.h>
 #include <vga.h>
 
int main (void)
{
    vga_init();
    vga_setmode(G800x600x256);   /* Or another mode  */
    vga_setcolor(10);                     /* Any color number */

     vga_drawpixel(50,50);

/* Set back TEXT mode */
    vga_setmode(TEXT); 

     exit(EXIT_SUCCESS);
}

Sincerely,
Konstantyn.
