  2/11/2017 Ubuntu MATE for the Raspberry Pi 2 and Raspberry Pi 3 | Ubuntu MATEhttps://ubuntu-mate.org/raspberry-pi/ 1/4 Ubuntu MATE for the Raspberry Pi 2 and Raspberry Pi 3 Martin Wimpress and Rohith Madhavan have made an Ubuntu MATE image for the Raspberry Pi 2 and Raspberry Pi 3 which you can download or build yourself. The image is based on the regular Ubuntu armhf  base, not the new Snappy Core, which means that the installation procedure for applications is the same as that forthe regular desktop version, ie using apt‐get . However, since Ubuntu MATE 16.04 snap packages can be installed alongside classic deb packages. We have done what we can to optimise the build for the Raspberry Pi 2 and Raspberry Pi 3, you can comfortably use applications such as LibreOffice, which in fact is ajoy to use :-) But the microSDHC I/O throughput is a bottleneck so  we 󰁨󰁩󰁧󰁨󰁬󰁹    recommend that you use a Class 6 or Class 10 microSDHC  card. Ubuntu MATE16.04 also has fully working Bluetooth and Wifi on the Raspberry Pi 3  You’ll need a microSD card which is 8GB  or greater to fit the image. The file system can be resized to occupy the unallocated space of the microSD card, on UbuntuMATE 16.04 this can be done via Ubuntu MATE Welcome . NOTE! There are no predefined user accounts . The first time you boot one of the desktop images it will run through a setup wizard where you can create your ownuser 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. Ubuntu MATE 16.04 running on the Raspberry Pi 3. Download Run Ubuntu MATE on your Raspberry Pi 2 or 3 today. Download Ubuntu MATE (../download/) Known Issues During first boot configuration Ubiquity does not prompt to join available WiFi networks.#1572793 (https://bugs.launchpad.net/bugs/1572793)Upon completion of the first boot setup WiFi doesn’t work, at all. Reboot and WiFi will be available.#1572956 (https://bugs.launchpad.net/bugs/1572956)Both these issues will be addressed in Ubuntu MATE 16.04.1 for Raspberry Pi 2 and 3 which is due in late July. Making a microSDHC  The image can be directly written to a microSDHC using a utility like dd , but we prefer ddrescue  (from the gddrescue (apt://gddrescue), for example:  2/11/2017 Ubuntu MATE for the Raspberry Pi 2 and Raspberry Pi 3 | Ubuntu MATEhttps://ubuntu-mate.org/raspberry-pi/ 2/4 sudo apt‐get install gddrescue xz‐utils unxz ubuntu‐mate‐16.04‐desktop‐armhf‐raspberry‐pi.img.xz sudo ddrescue ‐D ‐‐force ubuntu‐mate‐16.04‐desktop‐armhf‐raspberry‐pi.img /dev/sdx  The microSDHC may be presented on any /dev/sdX  so use the command lsblk  to check. 󰁐󰁯󰁷󰁥󰁲󰁥󰁤󰁢󰁹 󰁡󰁳󰁣󰁩󰁩󰁮󰁥󰁭󰁡     00:00 Setting up gddrescue (1.19‐2) ...

Pass 1 (forwards) If you prefer a graphical tool we recommend using GNOME Disks (apt://gnome-disk-utility) and the Restore Disk Image…  option,  which natively supports XZcompressed images . sudo apt‐get install gnome‐disk‐utility Making a microSDHC with Windows If you want to make a microSDHC using Windows we recommend:7-Zip (http://www.7-zip.org/) to extract the image. Win32 Disk Imager (http://sourceforge.net/projects/win32diskimager/) to write the image. Re-size le system Ubuntu MATE 16.04  You can use Ubuntu MATE Welcome to resize to automatically resize the partitions to make full use of your microSHDC card capacity. Simply click the large Raspberry Pi Information  button on the Welcome screen, click the Resize  button and then restart the Raspberry Pi. Manual Method It’s not hard to do manually. Once booted: sudo fdisk /dev/mmcblk0 Delete the second partition (d, 2), then re-create it using the defaults (n, p, 2, enter, enter), then write and exit (w). Reboot the system, then:  2/11/2017 Ubuntu MATE for the Raspberry Pi 2 and Raspberry Pi 3 | Ubuntu MATEhttps://ubuntu-mate.org/raspberry-pi/ 3/4 sudo resize2fs /dev/mmcblk0p2 Enable and Disable X11  We created a simple utility called graphical  to disable/enable the MATE desktop environment for easily creating a headless “server”  . Executing  graphical disable  will present a console login on the next boot, with no X11 or associated services running. If you want to get the full Ubuntu MATE desktopback, run graphical enable  and reboot. Hardware accelerated video with omxplayer Most videos will play with hardware acceleration using omxplayer  which is pre-installed in Ubuntu MATE. However if you have MPEG-2 or VC-1 video video filesthen  you will need MPEG-2 and/or VC-1 licenses from the Raspberry Pi Store (http://www.raspberrypi.com/license-keys/) . Redirecting audio output  You can select which audio device omxplayer  should output audio to. For HDMI omxplayer ‐o hdmi video.mp4 For 3.5mm audio jack omxplayer ‐o local video.mp4  The sound will output to HDMI by default if both HDMI and the 3.5mm audio jack are connected. You can, however, force the system to output to a particular deviceusing amixer . For HDMI sudo amixer cset numid=3 2 For 3.5mm audio jack sudo amixer cset numid=3 1 Hardware accelerated video with VLC and mpeg Ubuntu MATE 16.04 added OpemMAX IL hardware accelerated video playback to VLC and MMAL hardware accelerated video playback to ffmpeg. To enable hardware accelerated video playback in VLC go to Tools  -> Preferences  -> Video  and select OpenMax IL . To use hardware accelerated video playback with ffplay  you must specify the h264_mmal  codec ffplay ‐vcodec h264_mmal video.mp4 Hardware accelerated playback on the Raspberry Pi works by overlaying the video directly to the screen. Therefore there are no onscreen controls for playback control. You’ll need to use the VLC and ffmpeg keyboard shortcuts. VLC keyboard control (https://wiki.videolan.org/Hotkeys_table/)ffplay keyboard controls (https://ffmpeg.org/ffplay.html#toc-While-playing) Feedback and Improvements Please post all feedback on the dedicated community forum (https://ubuntu-mate.community/c/support/raspberry-pi-2).
