I'd give it a good 5 minutes before giving up. Then there's boot options. For my sins, I had an Sis 6326 video card and no linux would see it, because the 16 vga modes were used for compatibility reasons weren't provided in the sis 6326. The solution was to boot with
and use an ncurses interface.
That was bacvk then. Find the boot options today for mint, and try some of them. There's always something for crappy video issues.
