svgalib : cant see anything

Answer 1

So do you have other SVGAlib applications working on your system? Such svgatest, which may be in a separate distribution package (svgalib-bin or similar).

Have you configured svgalib for your system? Common locate of the config file is /etc/vga/libvga.config and read man svgalib should give you more details.

I suspect that once you have SVGAlib working in general, the tutorial example program will work.
