Don't have to; in 99% of cases the default drivers / the stuff on the installation disc will work fine. Usually it's wireless that's causing the problems if any; though now that Atheros has gone open source that is changing fast. If any proprietary drivers need to be installed, it's a matter of few mouse clicks. Really simple TBH; unless the wireless drivers are the problem, those can be a pain to get working (welcome to the terminal).Well I'm glad to hear that it will run but I am curious what about installing my drivers.
So it's all pretty simple.
Except for when it isn't. I've had a good luck with my hardware and Ubuntu, but there are some who haven't been quite so fortunate.
