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 zram
Install/setup nfs mounts for remote shares.
Increased the size of the root patrician.
Installed/Setup sshd
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
Problems:
-
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?
Thanks, Goof
