Upgrade notes Ubuntu 12.04 to 14.04

Just a few things I encountered in my upgrade on my Zotac Zbox going to from Ubuntu Precise (12.04) to Ubuntu Trusty (14.04)

  • Couldn't get it to use an iso as the upgrade material since there's no alternate cd anymore, so did an online upgrade which worked fine.

Fixes:

  • Atheros driver is way better, I went from 1 Mbps to 4 Mbps on Speedtest.net, nothing else changed in my network, the latter speed what I always got from other computers.
  • Streaming video full screen no longer requires gpu acceleration to be disabled.

Bugs (related):

  • nouveau driver hiccups on sound every few seconds when streaming videos
  • Nvidia Ion graphics/sounds always transmits sound on HDMI even if you switch to analog. In my case this provided a weird problem, where I couldn't use analog audio to bypass the previous bug above. See fix below...

Workarounds:

  • Installed the Nvidia drivers, which had major issues in 12.04 (screen blank or not lined up with monitor/tv) - works great now
  • Forgot that Amazon Prime streaming require hal for flash drm get it from this  ppa
  • Chromium and Chrome no longer work with Adobe flash from the repos, you need pepperflash
    sudo apt-get install pepperflashplugin-nonfree
    sudo update-pepperflashplugin-nonfree --install
    
  • If you're using Apache pay attention to the 2.2 to 2.4 upgrade, syntax of allows and conf file names changed and are important.
