Notes on setting up Ubuntu 16.10 (Yakkety Yak) on Intel NUC6i7KYK tech-spec [PDF]
- Intel NUC6i7KYK - 6th generation Intel® Core™ i7-6770HQ processor with Intel® Iris™ Pro graphics (2.6 to 3.5 GHz Turbo, Quad Core, 6 MB Cache, 45W TDP).
- 950 PRO NVMe M.2 SSD - 256Gb, NVMe SSD powered by Samsung V-NAND technology. Up to 2,200MB/s sequential read and 900MB/s write.
- Komputerbay 32GB ( 2x 16GB) SODIMM - Laptop Memory Upgrade DDR4 2400MHz PC4-19200 SODIMM 2Rx8 CL16 1.2v Notebook RAM.
- Microsoft All-in-One Media Keyboard.
Dowfnload 64-bit desktop ISO image (1.5Gb) from http://releases.ubuntu.com/16.10/ and use Startup Disk Creator to burn to a USB drive.
BIOS & firmware updates available from: https://downloadcenter.intel.com/product/89187/Intel-NUC-Kit-NUC6i7KYK
Enabling fast boot means that there is no straightforward way to get to the BIOS settings, as the splash screen with F2 / F7 / etc options is skipped entirely. With the machine powered off, press and hold the power button for 3-4 seconds then release. You should see a menu appear listing various options, one of which is BIOS Setup (press F2).
The power LED on the Intel® NUC blinks in a pattern if an error occurs during POST. Intel NUC products that include a front panel audio jack produce an audible beep pattern that you can hear through headphones or speakers plugged into that jack.
| Code | Diagnosis | Pattern |
|---|---|---|
| 3 blinks (3 beeps) | Memory error | On-off (1.0 second each) three times, then 2.5-second pause (off). The pattern repeats until the computer is powered off. Some memory sticks, while supported by hardware spec, can still cause issues. Some errors can be fixed by removing one stick if two are installed. A non complete list of supported RAM can be found here. |
| Continual blinks | BIOS Update in progress | Off when the update starts, then on for 0.5 seconds, then off for 0.5 seconds. The pattern repeats until the BIOS update is complete. |
| 2 blinks (2 beeps) | Video error (when no VGA option ROM is found) | On-off (1.0 second each) two times, then 2.5-second pause (off). The pattern repeats until the computer is powered off. |
| 16 on/off blinks (8 beeps) | CPU thermal trip warning | 0.25 seconds on, 0.25 seconds off, 0.25 seconds on, 0.25 seconds off, for a total of 16 blinks. Then the computer shuts down. |

On Installation type screen, don't pick 'Encrypt the new Ubuntu installation for security': Use home folders encryption instead.
Alter /etc/fstab to set the root partition options to include noatime.
Remount with sudo mount -o remount / (does not need a reboot).
Swap was original set at 32Gb - not really a good use of expensive SSD, so this was reduced down to 4Gb, and then the space reclaimed into the root partition.

Generate an RSA public/private keypair with ssh-keygen. Upload the public key
to github, and add to https://github.com/rm-hull/dotfiles/blob/master/.ssh/authorized_keys
From a command prompt:
$ sudo apt-get install git
$ git clone [email protected]:rm-hull/dotfiles.git
$ cd dotfiles
$ ./bootstrap.sh
Answer 'y' when prompted.
Copy ~/.apt-lists/* into /etc/apt/sources.list.d as root, and trust the keys:
$ sudo cp -av ~/.apt-lists/*.list /etc/apt/sources.list.d
$ sudo apt-key add ~/.apt-lists/TRUSTED-KEYS.txt
Install some common packages from the Ubuntu mines:
$ sudo apt-get install git htop tree nfs-client sshfs gimp openssh-server \
exhuberant-ctags silversearcher-ag postgresql postgresql-client \
openvpn network-manager-openvpn network-manager-openvpn-gnome \
optipng p7zip unrar mplayer ffmpeg gitg conky-all acpi vim-gtk \
ttf-mscorefonts-installer
Next install some packages from other sources:
$ sudo apt-get install virtualbox-5.1 oracle-java8-installer \
google-chrome-stable intellij-idea-community mongodb-org nodejs \
sbt
Create a mount point with sudo mkdir -p /mnt/atrax and add the following
entry to /etc/fstab:
192.168.1.65:/ /mnt/atrax nfs4 _netdev,auto,intr,timeo=14,x-systemd.device-timeout=3s,nofail,noatime 0 0
Mount it, and re-assign links:
$ sudo mount /mnt/atrax
$ cd ~
$ rm -rf Documents Music Videos Pictures
$ ln -s /mnt/atrax/users/rhu/Documents
$ ln -s /mnt/atrax/media/Music
$ ln -s /mnt/atrax/media/Photos Pictures
