Whereas
Suspend & graphics are (ahem)interacting poorly on the Dell M3800 under Fedora 21.
Question
But does it work with the Ubuntu shipped from the factory by Dell? TBD.

Experiences with the Dell M3800, The Good, The Bad (no Ugly, it’s a beautiful machine)
Evidences
- Fedora 21
- Kernel 4.0.7
Linux devbox.example.com 4.0.7-200.fc21.x86_64 #1 SMP Mon Jun 29 22:11:52 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux - $ rpm -q -a | grep nouveau

Actualities
Graphics Crashes
These manifest as the graphics becomes inoperable; the CPU is running hard, the fan is running hard. Even virtual consoles will not work. You must powercycle.
