Putting the image on microSDHC

Download the image and then:

1. Extract the .img.bz2 archive to get the image file.bunzip2 ubuntu-mate-15.10-desktop-armhf-raspberry-pi-2.img.bz2
2. Write the image file to the microSD card as root.sudo ddrescue -d -D –force ubuntu-mate-15.10-desktop-armhf-raspberry-pi-2.img /dev/sdX

The drive may be mounted on any /dev/sdX so use the command lsblk to check.

Re-size file system

There are no utilities included for automatic file system re-sizing. However, 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:

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 now X11 or associated services running. If you want to get the full Ubuntu MATE desktop back, run graphical enable and reboot.

Hardware accelerated video

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 files then you will need MPEG-2 and/or VC-1 licenses from the Raspberry Pi Store.

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 device using amixer.

For HDMI

sudo amixer cset numid=3 2

For 3.5mm audio jack

sudo amixer cset numid=3 1
