I mostly got the Raspberry pi 2, and re-installed it a few weeks back with ubuntu mate 15.04 because of problems.
First, what’s the difference between ubuntu-mate for the Pi 2 and ubuntu for the Pi and installing mate? I am pretty sure the original install was ubuntu-mate but I’m second guessing myself as and some of these problems are new.
First some notes about the setup:
Not doing any over clocking.
Purchased/enable other video codecs
Disabled things like printing, bluetooth, auto update to save resources
Install/setup nfs mounts for remote shares.
Increased the size of the root patrician.
Installed things like vlc, xbmc, chrome, gstreamer
daily cronjob to restart irqbalance
changes to config.txt to make use of full display
compiz is disabled
Had huge memory/resource issues. After first install while updating via gui and firefox could not work at the same time. Also irqbalance often takes up all the resources.
VLC black screen and audio fades in/out. Even after changing Video output to “X11 (XCB)” it only works if window size is unaltered. So, fix is not a fix, but at least it’s something.
I’ve tried various video and audio output and other options. I have tried various gpu_mem options from 128 to 320 in /boot/config.txt
[rant]And omxplayer, No controls and basically locked out of box until movies finishes. (15.10 says there is a gui now?) But wouldn’t it be easier to distribute VLC with hardware support than develop a new player?[/rant]
Differences in the two Ubuntu raspberry pi distro’s?
How to optimize resources?
How to get VLC working full screen? And address the audio fade in/out?
What options exist for playing online html5/flash based videos?
What is best way to drop resolution to 720p?
Best options for config.txt for playing videos?
