Ubuntu 16 04 2 and Ubuntu 17 04 Beta 1 plus flavours

Ubuntu 16 04 2 and Ubuntu 17 04 Beta 1 plus flavours


Please note my blog is intended to be the dynamic update content partner to my static core content pages on my website. This particular post relates to my http://www.linuxium.com.au/how-tos/runningubuntuontheintelcomputestick page where Ive created some Ubuntu ISOs whose purpose is to better support Intel Atom based devices. 

As Canonical just released Ubuntu 16.04.2 with the rolling Hardware Enablement (HWE) kernels which aim to provide support for the latest hardware Ive decided to provide a single kernel which is effectively a HWE edge kernel specifically patched for Intel Atom SoCs in my ISOs to simplify kernel management and create a forward path for future migration to mainline kernels.

My kernel is based on Canonicals next zesty kernel which is rebased to v4.10 and also available in xenial as hwe-edge. Whilst v4.10 is the latest mainline kernel to be released the merge window for v4.11 now includes the revised HDMI LPE Audio Support patch set together with the AXP288 power supply patch set for Intel Atom SoCs. Because v4.11 will be released in a couple of months with the patches being included in Ubuntu hopefully by 17.10 Ive added these latest patches from the merge window to my kernel. Besides the HDMI LPE patches from Pierre-Louis Bossart, Jerome Anand & Takashi Iwai and Hans de Goedes AXP288 patches Ive also added Hans de Goedes PWM, I2C, CX2702X audio support, Silead touchscreen support and ASUS tablet function key support patches. Also included is Mika Kuoppalads new anti-freeze patch, Pierre-Louis Bossarts PMC Platform Clock and Codecs patches, Ville Syrj�l� atomic update fix, Bastien Noceras wifi patch, Laszlo-Fiats bluetooth patch, Jonas Aabergs bluetooth patch for the ASUS 100HA together with my bluetooth support which is based on a script from Larry Finger. The kernel source is available on my github.

At this stage Im providing ten ISOs: 16.04.2 releases of Ubuntu, Lubuntu, Xubuntu, Ubuntu MATE, Ubuntu GNOME and Kubuntu all with kernel Ubuntu-lts-4.10.0-10.12~16.04.2 together with Ubuntu 17.04 pseudo Beta 1 and 17.04 Beta 1 releases of Lubuntu, Xubuntu and Ubuntu Budgie all with kernel Ubuntu-4.10.0-10.12. Technically the two kernels are the same with the xenial LTS kernel being a backport of the zesty kernel. Note that the Ubuntu 17.04 Beta 1 is a pseudo release because there is no official Beta 1 release so I have used the daily release provided the same day the official Beta 1 flavours were released. Ive also included Ubuntu Budgie as it is now an official Ubuntu flavour and I thought there may be some interest. Further flavours will be added later although I am no longer going to provided updated 16.10 releases due to resource constraints. I am also providing the corresponding kernel update scripts and I will maintain the kernels with security patches and/or Intel Atom SoC added functionality/improvements.

Ubuntu Budgie is stable and easy to use that integrates the Budgie Desktop environment into Ubuntu. Whether you are using it on the old computer, or powerful workstation, Ubuntu Budgie is adaptable to any device, keeping them fast and usable.

If freezing persists follow Len Brown suggestion of adding "intel_idle.max_cstate=2" as a kernel boot parameter which enables Core-C6 but disables module/package-C6. Open a terminal session and enter the following command (on a single line) sudo sed -i s/(GRUB_CMDLINE_LINUX=)""/1"intel_idle.max_cstate=2"/ /etc/default/grub. To implement the change enter sudo update-grub and then reboot the system by entering sudo reboot. The above change only needs to be made once, typically following installation to eMMC storage. Prior to embarking on an encrypted LVM installation you should first open a terminal session and turn off swapping using the command sudo swapoff -a. If there is no wifi after booting devices with a Broadcom chip then reload the driver: in a terminal window enter sudo modprobe -r brcmfmac followed by sudo modprobe brcmfmac. Occasionally on some devices bluetooth doesnt initially load so it is necessary to restart the service: for Broadcom chip devices enter sudo systemctl stop brcmbt.service followed by sudo systemctl start brcmbt.service and for Realtek chip devices enter sudo systemctl stop rtl8723bsbt.service followed by sudo systemctl start rtl8723bsbt.service. Some devices still do not reboot (or warm restart) correctly which can result in a purple screen or lack of wifi and/or bluetooth on reboot. In these circumstances cycle the power and boot the device from cold. Unfortunately as I dont have a tablet I cannot advise on the screen rotation issues however others have commented in previous posts with their solutions which Id recommend reading. WIP includes improving backlight support for some devices and the ES8316 driver which is currently under development.


Kernel update scripts are provided for updating the kernel and require my ISOs to be installed as a pre-requisite otherwise you will be missing the userland files required for audio, wifi and bluetooth. To upgrade the existing installed kernel to the later version provided by the script first download the script and after making it executable (enter chmod 755 ~/Downloads/<script>) install it as root (by entering sudo ~/Downloads/<script>). Once the script has finished executing the device will need to be rebooted to use the updated (patched) kernel. 

4.10.0-10.12 (latest zesty kernel)
4.10.0-10.12~16.04.2 (latest backported xenial kernel)

Dont forget when making a comment to include the name/model of your device and if reporting a technical issue please include a copy of the output from dmesg by sharing
