My macbook finally went kaput so I've decided to get an XPS 13" and run ubuntu on it. Ubuntu is nice and it mostly works well out of the box but there's a few things I've had to tweak and they're collected here.
I had a difficult time installing ubuntu at all because the way the BIOS is set up, the machine boots from a live disk before the SSD is ever mounted. Dell has the instructions for how to fix this:
Users should go to the system BIOS (F2 on boot up) and change the SATA setting to ACHI. Should the drive still not be seen after this change. Users should then follow the instructions below.
