Feedback

Is there anything you can help with or want to be involved in? Maybe you just want to discuss your experiences or ask the maintainers some questions. Please come and talk to us.

Many thanks to everyone who donated to the Ubuntu MATE project this month. You have been generous as always and ensured that we can meet all the costs associated with running the Ubuntu MATE project and the community site. In fact, this month we are able to reward some developers for working on Ubuntu MATE projects.

How will these donations be spent?

These donations will be used to pay for:

• All Ubuntu MATE hosting and development server costs for February 2016.
• All the Ubuntu MATE CDN, bandwidth and email charges for February 2016.
• Donated €1535 (taking into account currency variations) to 8 Open Source developers working on Ubuntu MATE and MATE Desktop projects.

Although Ubuntu MATE 15.04 onward is an official member of the Ubuntu family, and new Ubuntu MATE releases are now distributed via the Canonical mirror network, we are serving ~500 downloads per day for Ubuntu MATE 14.04 and another ~1400 downloads per day for Ubuntu MATE for the Raspberry Pi 2 and Raspberry Pi 3.

Thank you!

Supporting Open Source

Ubuntu MATE is comprised of many Open Source projects, we recognise that. Each month that Ubuntu MATE has a surplus of funds we will make a contribution to an Open Source project or developer that Ubuntu MATE directly benefits from.

For February 2016 Ubuntu MATE have donated to several Open Source developers who’ve worked on Ubuntu MATE or MATE Desktop projects.

• Luke Horwell (Ubuntu MATE) - £150 for working on Ubuntu MATE Welcome.
• Wolfgang Ulbrich (Fedora) - €100 for porting MATE Desktop to GTK3.
• Vlad Orlov (Linux Mint) - €100 for porting MATE Desktop to GTK3.

PayPal

• A total of $1400.81 was donated via PayPal, which after processing fees amounted to $1276.86, of which $885.59 was received as Download Tips.
• A total of €207.5 was donated via PayPal, which after processing fees amounted to €194.14.
• A total of £35.0 was donated via PayPal, which after processing fees amounted to £33.16.

The Raspberry Pi 3 Model B is here and we are delighted to announce the immediate availability of Ubuntu MATE 15.10 for the Raspberry Pi 3 Model B!

Many thanks to Ben Nuttall, Simon West, Liz Upton and Phil Elwell from the Raspberry Pi Foundation for providing Martin Wimpress with a Raspberry Pi 3 and engineering assistance over the weekend.

The Raspberry Pi 3 Model B is the same form factor as the Raspberry Pi B+ and Raspberry Pi 2 Model B, the RAM remains 1GB and the USB and wired Ethernet port arrangement and configuration are unchanged.

Here is what is new to the Raspberry Pi 3:

• Improved performance thanks to a Broadcom BCM2837 64-bit Quad Core ARM Cortex-A53 CPU running at 1.2GHz.
• Integrated 802.11 b/g/n Wireless LAN (BCM43438) accessed via SDIO using the Arasan MMC controller.
  • This requires that the Broadcom MMC controller is used for the SD card using the relatively new and recently revamped bcm2835-sdhost driver.
• Integrated Bluetooth 4.1 (Classic & Low Energy) (BCM43438 again) is presented as a modem via a serial UART (two-wire - no hardware flow control) with the BlueZ software stack running in H4 mode.
• Improved power management with a 2.5 Amp power supply.
• A new chip antenna is where status LEDs were previously located. The status LEDs are still on the board, right next to the microSD card slot.

The Ubuntu MATE image we’ve prepared supports the integrated Wifi on the Raspberry Pi 3 but support for the integrated Raspberry Pi 3 Bluetooth is still in progress and we hope to enable full support via an update very soon.

The image will fit on a 4GB (or larger) microSHDC card, is pre-configured to enable access to Raspberry Pi 2 and Raspberry Pi 3 hardware devices such as GPIO, SPI, I2C etc and include replacement memcpy and memset functionality for the Raspberry Pi to optimise performance. We have done what we can to optimise the builds for the Raspberry Pi 2 and Raspberry Pi 3 but microSDHC I/O throughput can be a bottleneck so we recommend that you use a Class 6 or Class 10 microSDHC card.

The image is built from the regular Ubuntu armhf base, not the new Snappy Ubuntu, which means that the installation procedure for applications is the same as that for the regular desktop versions ie using apt-get. The images will only work in a Raspberry Pi 2 Model B and Raspberry Pi 3 Model B

The first time you boot one of the desktop images it will run through a setup wizard where you can create your own user account and configure your regional settings. The first boot is quite slow but, once the first boot configuration is complete, subsequent boots are much quicker.

Changes

These are the changes that we’ve made since the 15.10.1 release:

2016-02-27 - 15.10.3 for Raspbery Pi 2 and Raspberry Pi 3

• Added support for Raspberry Pi 3 integrated Wifi.
• Updated BlueZ 5.35 with patch to support the Raspberry Pi 3 integrated Bluetooth.
  • Support for the integrated Raspberry Pi 3 Bluetooth is not working but we hope to have an update that addresses this soon.

2016-02-26 - 15.10.2 for Raspbery Pi 2 and Raspberry Pi 3 (internal testing build)

• Added support for Raspberry Pi 3 Model B.
  • No Raspberry Pi 3 integrated Wifi or Bluetooth support.
• Updated to Linux 4.1.18.
• Updated all packages to the current version in the Ubuntu 15.10 archive.
• Fixed an issue where the SSH host keys were not correctly regenerated on first boot.
