Conventional wisdom says small, powerful embedded Linux like the Raspberry Pi, Beaglebone, or the Intel Edison are inherently manufactured devices, and certainly not something the homebrew tinkerer can produce at home. [hak8or] is doing just that, producing not one, but two completely different tiny Linux computers at home.
The first is based on Atmel’s AT91SAM9N12 ARM processor, but the entire board is just about two inches square. On board is 64 MB of DDR2 DRAM, a USB host and OTG port, and not much else. Still, this chip runs a stripped down Linux off of a USB drive.
Setting aside the head-scratching title, Linux 4.0 isn’t a massive change from Linux 3.19. It would have been named Linux 3.20, but lots of people wanted to see Linux 4.0. As Linus Torvalds himself said, “the strongest argument for some people advocating 4.0 seems to have been a wish to see 4.1.15 - because ‘that was the version of Linux Skynet used for the T-800 Terminator.’”
LMDE (Linux Mint Debian Edition) is a very exciting distribution, targeted at experienced users, which provides the same environment as Linux Mint but uses Debian as its package base, instead of Ubuntu.
LMDE is less mainstream than Linux Mint, it has a much smaller user base, it is not compatible with PPAs, and it lacks a few features. That makes it a bit harder to use and harder to find help for, so it is not recommended for novice users.
Simply put, there is no actual official NVIDIA support for Optimus technology for Linux. Or at least, not completely. Until recently, there was none at all. As of 2013, NVIDIA did start to provide initial support for Optimus, but it is extremely barebones and arguably doesn't actually properly implement the Optimus features as it's meant to be.
But let's look at the current options for running an NVIDIA Optimus-enabled computer with Linux...
