Finding Notebook Hardware for Ubuntu - 2015 Edition
Unfortunately it is still much harder than necessary to find notebook hardware to use with Ubuntu (or other Linux variants). This blog is full of past experiences (some of them quite time-consuming) on finding notebook hardware that will work without too much fiddling. This short note is to document my recent research on that front to help others who want to do the same (as there doesn’t seem to be a lot of good current info around).
SShuttle - quick and temporary VPN over SSH
Every once in a while you find a gem. One of these for me is SShuttle – until now I have not known about this one.

Use-case: I just been trying to get Ubuntu Make to install Eclipse IDE and the local AARNET download mirror is just refusing to cooperate (https://github.com/ubuntu/ubuntu-make/issues/90). A quick forward to a remote VPS fixed the issue without headaches

Raspberry Pi Prerequisites
Since this will be a purely headless install designed to sit in a corner behind the scanner I am using a Base Raspian (Debian Wheezy) install (I personally like the clean minimal install via https://github.com/debian-pi/raspbian-ua-netinst the best).
Install Ubuntu 14.04 on a Chromebook
There are plenty of sites out there that give advise on this topic, unfortunately most of them are highly ad-infested to the point of being unreadable as well as only containing single bit rather that an overall picture. This is a collection of useful links to source materials as well as steps necessary to install.

CyanogenMod 12 on Sony Xperia Z2
Just a quick update of the previous article on “Sony Xperia Z2 upgrading to CyanogenMod 11“.
One thing is that CM now included the custom recovery and you do not need to download any other custom recoveries !
Download the CM 12 ZIP file for Sony Xperia Z2 (sirius) and extract the ‘boot.img’ file
Download link: https://download.cyanogenmod.org/?device=sirius
Get the device into fastboot (bootloader mode)
Ubuntu 14.04 Webmin Install from PPA
On remote systems sometimes a web-based tool can be very handy. Webmin is such a tool that has been well maintained for decades. To install quickly on a Ubuntu Server without having to manage dependencies and keeping it updated as part of normal OS update operations installing from a PPA Repo is handy.
sudo echo "deb http://download.webmin.com/download/repository sarge contrib" >> /etc/apt/sources.list
wget -q http://www.webmin.com/jcameron-key.asc -O- | sudo apt-key add - sudo apt-get update sudo apt-get install webmin`
Barebone Ubuntu 14.04 Cloud Desktop
Since I have found some issues with my previous LXQT setup in real-life work I decided to fall back to standard Lubuntu for my cloud desktop. As part of this I also switched to TightVNC which seems a lot easier to configure.
Add local user account
adduser USERNAME
adduser USERNAME sudo
Install Lubuntu Desktop
sudo apt-get install --no-install-recommends lubuntu-desktop tightvncserver
TightVNC Configuration
sudo vim /etc/lightdm/lightdm.conf
#
# VNC Server configuration
#
# enabled = True if VNC connections should be allowed
# port = TCP/IP port to listen for connections on
#
[VNCServer]
enabled=true
port=5900
width=1366
height=768
depth=24
sudo /etc/init.d/lightdm restart
Connect to the remote system
ssh -L 5900:localhost:5900 -i /path/to/your/aws/keyfile.pem YOUR.EC2.IP.ADDRESS

Accessing your cloud desktop from Chromebook
One of the main reasons for setting up a cloud desktop is that I tend to use a lot of different devices some of which are not very powerful.
One of my favorite devices of late has been a HP 11 Chromebook. I originally bought it for a new employee and wanted to check myself how this thing stacks up to do day-to-day computing tasks more efficiently than a standard laptop without all the headaches of running Windows (viruses, endless driver installs, bloatware, malware, …). We already have several people at work working exclusively from Chromebooks and they absolutely love them. Long story short – I ended up keeping the Chromebook for myself as it’s an absolutely great secondary device for me. I can carry it with me everywhere (doesn’t weigh much more than a tablet, roughly the same size as a tablet & has a keyboard and is so much more useful than a tablet).
Vodafone LTE mobile data on Cyanogen Mod
I have had some issues recently with getting LTE (4G) connectivity on the Vodafone Australia Network using CyanogenMod 11 on multiple devices (http://forum.cyanogenmod.org/topic/92919-no-4g-signal-on-vodafone-au/). Turns out that it was an APN issue after all.
The APN provisioned by default when the Voda SIM card is inserted (vfinternet.au) does not work for the LTE Data Network. It works with GPRS & WCDMA, but fails to connect when the phone is set to prefer LTE (4G) Networks and they are actually available. It means that the handset will loose mobile data connectivity altogether. There are various APN Settings floating around on the interwebs, but any I tried previously did not fix the issue.
Sony Xperia Z2 upgrading to CyanogenMod 11
Contrary to my normal inclinations not to buy anything but Stock Android phones I ended up with a Sony Xperia Z2 in a hurry over the weekend (it’s a long story…). It appears to be quite a decent handset (with a pretty good camera actually) and one of the main reason to choose this over the other options was that is was one of the few high-end devices which already had a CM snapshot rather than just nightly releases. However similar to their colleagues at Samsung the Sony people also opted to stuff all sorts of crap-ware bloat onto the Android base OS. It appears not to be as bad as the Samsung (who are the kings of crap) mods, but for somebody used to the clean Android experience it’s just very annoying. So I opted to flash it straight to CyanogenMod.
Removing 'Video Call' default in Google Calendar
This ‘feature’ has been annoying me for a while and after this has caused some confusion with some of my clients I decided to go and look where to disable this. Why this has been made a system wide default is beyond me.
Rather than in the users Calendar Settings this is actually in the Google Apps Admin Console (https://admin.google.com/)
Console –> Google Apps –> Settings for Calendar –> Sharing Settings
