Unfortunately I do not know how to identity the graphics chip, for the Gigabyte spec page does not provide it. > If your chip isn't yet supported by the kernel (which is doubtful for intel), > it'll fallback to known standards that every manufacturer should support.

But I first need to know if the backport kernel supports the graphics chip. There is a 15.5.rc6 backport for Debian. It seems worthwhile to try it out, but I don't know how to tell apt-get to intstall a backported kernel from a Debian site. > If there is something being displayed on your screen, you then have something > capable of computing graphics.

Sorry I thought I has said that I had no graphics card.
