Ensure that you have the contrib and non-free repositories enabled in your sources list, then (or equivalent with your preferred package handler): # aptitude update # aptitude install firmware-linux-nonfree I always install firmware-linux-free at the same time if it is not already installed. Everything might now be fine. If not, reboot to restart everything. If stil not, come back again. Lisi
