So I was building a computer that I intended to install Ubuntu on. As I ordered the parts a friend told me that not all hardware manufacturers supply Linux drivers for their hardware. This made me sway from the OS as I had already ordered the parts and I thought it would all work out either way. As I understand it, it's more about choosing hardware suitable for ubuntu rather than just picking a solid computer together and then just get all the necessary drivers.
So my questions are:
What hardware manufacturers have linux drivers availiable for certain?
and
Which ones should you avoid when choosing?
