How to Upgrade to Linux 4.8 in Ubuntu 16.04.2

I had read from several news sources that Ubuntu 16.04.2 would come with Linux 4.8. My system was upgraded from Ubuntu 16.04.1 to Ubuntu 16.04.2 this week-end, but I still had Linux 4.4.

cat /etc/lsb-release 
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=16.04
DISTRIB_CODENAME=xenial
DISTRIB_DESCRIPTION="Ubuntu 16.04.2 LTS"
uname -a
Linux FX8350 4.4.0-62-generic #83-Ubuntu SMP Wed Jan 18 14:10:15 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

cat /etc/lsb-release

DISTRIB_ID=Ubuntu

DISTRIB_RELEASE=16.04

DISTRIB_CODENAME=xenial

DISTRIB_DESCRIPTION="Ubuntu 16.04.2 LTS"

uname -a

Linux FX8350 4.4.0-62-generic #83-Ubuntu SMP Wed Jan 18 14:10:15 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

So I wondered why that was, and eventually found my answer on Reddit thanks to EndofLineLF user: If it isn’t a new 16.04.2 installation then you won’t have newer kernel. If your install started as 16.04 or 16.04.1 then with all updates installed “lsb_release” will display 16.04.2 as version because that’s what you have. The switch to HWE (Hardware Enablement Stack) was never automatic. So if you want newer kernel you have to install it manually. https://wiki.ubuntu.com/Kernel/RollingLTSEnablementStack#Packages-1 sudo apt-get install –install-recommends xserver-xorg-hwe-16.04 This will also install the new HWE kernel because it is recommended for that package. Upgrading to the new kernel is completely optional, and Linux 4.4 will still get security updates, but I did […]

Review & Quick Start Guide for Khadas Vim Pro Development Board with Ubuntu 16.04

Khadas Vim is the only Amlogic S905X development board I’m aware of. There are 4 or 5 versions of the board, but currently only two models are sold: Khadas Vim with 8GB flash and single band WiFi + BLE 4.0, and Khadas VIM Pro with 16GB flash, and dual band WiFi + BLE 4.2. SZWesion, the company behind the board, has sent Khadas Vim Pro for evaluation. Today, I’ll take a few pictures of the board and its accessories, and report my experience playing with Ubuntu 16.04.2 on the board. They’ve also released Android, LibreELEC, and dual boot Android/Ubuntu (for Vim Pro only) images, which you can find in the firmware resources page. Khadas Vim Pro Unboxing and Photos My parcel included Khadas package that looks like a book, an HDMI cable, and the same IR remote control sent with GeekBox, the first board made by the company, and powered […]

Baikal T1 BFK 1.6 MIPS Development Board Tested with OpenWrt

Baikal Electronics is a Russian fabless semiconductor company specializing in ARM and MIPS-based SoC, and we’ve already covered their Baikal T1 MIPS SoC announcement, as well as Tavolga Terminal TP-T22BT Debian 8 All-in-One Computer based on the processor. The company also have Baikal T1 BFK 1.6 development board, which does not appear to be publicly available yet, but one member of Habrahabr.ru forums got hold of one sample, and tested the OpenWrt SDK in Debian 8 host computer. First, we’ll have a look at the hardware they received. I don’t have the full specs of the board, but we’ll learn a little more below, in the meantime we can see two USB ports, Gigabit Ethernet ports, a 10GbE SFP cage, an mPCIe slot (I think), and two DB9 connector, as well as a bunch of other headers and connectors with SATA, GPIO, UART, I2C, SPI… I’ve then downloaded Baikal T1 BSP […]

Dride is a Voice Controlled Dashcam Driving Assistant Powered by a Raspberry Pi Board (Crowdfunding)

Next Thing introduced Dashbot Car Dashboard Assistant based on CHIP Pro module late last year, and it will get some competition with Dride, a driving assistant powered by Raspberry Pi, that can also be voice controlled like Dashbot, but includes a Pi camera to record videos, and alert the users of dangers using computer vision, for example when they drive too close to the car in front. The system leverages Raspberry Pi board and Pi Camera, and adds an outer shell, Dride’s Raspberry Pi HAT, and a car charger & cable. Some of the key features listed for the Dride include: Cloud support – Upload and store driving videos to your Dride profile ADAS – Safety alerts in case of lane deviation or frontal collision Voice – Voice commands for navigation & messaging Connectivity – Bluetooth, WiFi, and GPS The developers also provide “Dride – Passenger Seat Driver” app for […]

How to Assign Brightness Keys in Ubuntu 16.04 and Greater

Yesterday, I installed Ubuntu 17.04 in CHUWI LapBook 14.1, and was surprised everything appeared to work properly. However, the laptop does not come with brightness up and down keys. So I looked for ways to assign other keys to adjust brightness on the laptop, and eventually found a solution on AskUbuntu, and tried the options for Ubuntu 16.04. First we need to install xdotool, a utility that simulate keyboard input and mouse activity:

sudo apt install xdotool

1	sudo apt install xdotool

Once it’s done, go to the Dash, start Keyboard settings app, select Shortcuts tab, and click on the + icon on the bottom of the window to bring up the “Custom Shortcut” window. Now fill the Name field with “Brightness Up”, and the Command field with:

xdotool key --clearmodifiers XF86MonBrightnessUp

1	xdotool key --clearmodifiers XF86MonBrightnessUp

Repeat the procedure with for the down key filling the Name field with “Brightness Down”, and the Command:

xdotool key --clearmodifiers XF86MonBrightnessDown

1	xdotool key --clearmodifiers XF86MonBrightnessDown

Now we should have our two brightness keys, and we […]

Installing Ubuntu 17.04 on CHUWI LapBook 14.1 Apollo Lake Laptop

[Update: The instructions below do not work with the newly manufactured models because CHUWI completely changed the hardware The company also disabled the Linux option in the BIOS (See comments in this post) So you may need to use rEFInd boot manager or isorepin.sh script to install Linux (and some drivers may still not work out of the box) ] Since I’ve completed the review of CHUWI LapBook 14.1 with Windows 10 last week-end, I’ve decided to give it a try with a Linux distribution, and I chose to go with a daily build of Ubuntu 17.04 since we’ve seen Apollo Lake platforms need a recent Linux kernel. While Ubuntu 17.04 will be officially release in April 2017, likely with Linux 4.10, the current (alpha) build comes with Linux 4.9. I had already quickly booted Ubuntu 17.04 on the Laptop from a USB drive flashed using Rufus right after the […]

Embedded Linux Conference & OpenIoT Summit 2017 Schedule

The Embedded Linux Conference 2017 and the OpenIoT Summit 2017 will take place earlier than last year, on February 20 – 23, 2017 in Portland, Oregon, USA. This will be the 12th year for ELC, where kernel & system developers, userspace developers, and product vendors meet and collaborate. The schedule has been posted on the Linux Foundation website, and whether you’re going to attend or not, it’s always informative to check out the topics. So as usual, I’ll make a virtual schedule for all 5 days. Monday, February 20 For the first day, the selection is easy, as choices are limited, and the official first day it actually on Tuesday. You can either attend a full-day paid training sessions entitled “Building A Low Powered Smart Appliance Workshop“, and the only session that day: 14:30 – 15:20 – Over-the-air (OTA) Software Updates without Downtime or Service Disruption, by Alfred Bratterud, IncludeOS […]
