[xubuntu] Xubuntu 16.04 & UEFI

What's going with this? It wanted me to tu off UEFI before installing drivers? I bued a copy of Xubuntu 16.04 yesterday to try on my older Lenovo B590, but this DVD of version 16.04 ts already in the recycle bin, and I regret wasting a perfectly good DVD on it! Fortunately I still had my DVD of Xubuntu 15.10 as a fallback; now its asking me to upgrade; not sure I want to do that!

Originally I had swapped my Xubuntu 15.10 for Ubuntu 14.04, because systemd was not 100% compatible with my Lenovo B590, but because I am not a huge fan of Unity, I wanted to try Xubuntu 16.04, Besides the UEFI issues, the new applications store is terrible compared to version 15.10, and so far no systemd issues with sleep/awake. Maybe the newer keels fixed this problem? And UEFI seems to be fine with Xubuntu 15.10, although Matthew Garret seems to claim otherwise in numerous tweets from January, 2016.
