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.

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)

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<br></br>wget -q http://www.webmin.com/jcameron-key.asc -O- | sudo apt-key add -<br></br>sudo apt-get update<br></br>sudo apt-get install webmin

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<br></br>adduser USERNAME sudo

Install Lubuntu Desktop

sudo apt-get install --no-install-recommends lubuntu-desktop tightvncserver

TightVNC Configuration

sudo vim /etc/lightdm/lightdm.conf

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).

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.

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.

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

Foursquare decided that it was too hard for them to compete with location services like Yelp and split their app into two separate apps. Whilst that might make sense to the 4Square CEO and his VC masters, it makes no sense from a users perspective. Foursquare can be a bit of a battery hog already, and having 2 apps to open and “annoy” you with notifications is not an improvement by any means. And if I wanted Foursquare to be Yelp – I would have used Yelp in the first place. So no – I do not want to install another separate check-in App (called Swarm). One battery hogging location app was enough.

Install dependencies

sudo yum groupinstall "Development Tools"<br></br>sudo yum install kernel-devel

Mount the Virtualbox Additions CD ISO

sudo mkdir /media/cdrom/<br></br>sudo mount /dev/cdrom /media/cdrom/<br></br>sudo ./VBoxLinuxAdditions.run

Since I am a bit of a sucker for German “Krimis” as well as some their excellent documentaries I like to watch ARD Mediathek IPTV. However there are several problems with this when you live at the opposite side of the world. ARD has a block for any films that are 15+ years outside of 20.00h-6.00h GMT+1. Which makes it pretty much impossible to watch at a reasonable time in Australia. I also like to watch these things on the plane which requires download of the media files.

Using Amazon EC2’s free usage tier to host your own cloud desktop is a very economical way to to have a desktop at hand anytime you can not be near one. Since I quite often use Chromebooks these days when on the road this is a particular handy way should I need a full desktop for certain tasks.

Since Ubuntu 14.05 is my default desktop on my normal hardware I obviously want to have my cloud desktop running the same underlying OS. However I don’t think running Unity as the desktop interface would be appropriate via a low-bandwidth remote desktop connection. For this reason I chose LXQT. If you need total stability you probably should go for the more mature LXDE instead, but I have already tried LXQT on an old EEE PC and was very impressed by the speed and low resource usage.
