First 2017 17.04 Alpha ISOs for Ubuntu and Lubuntu

Whilst the first of January maybe a public holiday for some it didn't stop Canonical releasing new Ubuntu and Lubuntu 17.04 (Zesty Zapus) Daily Build ISOs. So I've re-spun them to includes the 4.9 kernel with all the latest drivers and fixes for Bay Trail and Cherry Trail devices.

This is my first Lubuntu Alpha build ISO for anyone wanting to test the latest development work with the lightweight variant of Ubuntu.

Also as some Cherry Trail devices use the RTL8723BS wifi chip I've fine tuned these latest ISOs to improve its support.

To try an ISO download it from one of the links below (in red) and write it to a USB using either 'Rufus' in Windows or 'dd' in Linux.

Ubuntu
Ubuntu comes with everything. All the essential applications, like an office suite, browsers, email and media apps come pre-installed and thousands more games and applications are available in the Ubuntu Software Centre.


Lubuntu
Lubuntu is a fast, energy saving and lightweight variant of Ubuntu using LXDE. It is popular with PC and laptop users running on low-spec hardware.

Faster ISO Boots in 2017

One problem I've had with my ISOs is that they were always slow to start. Whilst only being an inconvenience rather than a functional issue I was able to spent time today in finding an improvement.

As a result I've respun my Ubuntu 17.04 Alpha 281216 (Daily Build) ISO so that 2017 gets off with a much quicker start.

To try the 'faster' ISO download it from the link below (in red) and write it to a USB using either 'Rufus' in Windows or 'dd' in Linux.

I'll incorporate the improvement in my other ISOs as and when they are respun with functional updates.

Cherry Picked Patches for Cherry Trail Devices

Benefits Bay Trail devices as well.

I've updated my 4.9.0-11.12 kernel to include Len Brown's patch to address kernel freezes (https://bugzilla.kernel.org/show_bug.cgi?id=109051#c628), Laszlo-Fiat's patch to stabilize the RTL8723BS driver (https://github.com/hadess/rtl8723bs/issues/76) and Hans de Goede's patches to address wifi issues (https://github.com/hadess/rtl8723bs/issues/80).

To upgrade your kernel download the shell script and after making it executable (enter 'chmod 755 <script>') you can install it as 'root' (by entering 'sudo <script>'). Once the script has finished executing the device will need to be rebooted to use the updated (patched) kernel.

4.9.0-11.12 (current latest Zesty kernel)

Additionally I've respun yesterday's Ubuntu 17.04 (Zesty Zapus) Daily Build (Alpha 281216) ISO to include this updated 4.9.0-11.12 kernel together with firmware to support the Broadcom BCM4330 wifi chip (e.g. Tronsmart Ara X5) and the Broadcom BCM43340 wifi chip (e.g. ASUS EeeBook X205TA).

To try the ISO download it from the link below (in red) and write it to a USB using either 'Rufus' in Windows or 'dd' in Linux.

Ubuntu comes with everything. All the essential applications, like an office suite, browsers, email and media apps come pre-installed and thousands more games and applications are available in the Ubuntu Software Centre.

To turn on wifi for mini PCs with Broadcom wifi chips it is often necessary to reload the driver. In a terminal window enter 'sudo modprobe -r brcmfmac' followed by 'sudo modprobe brcmfmac'.
