So the upgrade to 16.04 was such a hassle post-installation that I decided to wipe and try Fedora 23. So far everything is working except suspend (which, frankly, never worked in any version of Ubuntu for the m3800).
I'm curious if anyone else out there is trying Fedora, and if so, have you gotten suspend to work when closing your laptop lid and what did you have to employ to get that working properly?
On Fedora 23, suspend mode works perfectly after one tweak, but only while AC is plugged in. As soon as power is removed and the laptop is 100% on battery, it either won't suspend or it immediately wakes from suspend.
