ok, so here's the story...
About a week ago i upgraded to Ubuntu 16.04 xenial, and i've been loving it.
Then after a couple of days on the system it started to freeze periodically....to the point where i couldn't use the mouse, keyboard, shortcut keys, etc. The screen was still visible with all of my windows, but i was unable to interact with it at all.
On one of my 'power down...power up' restarts to get the computer working again i received an internal error (and sent off the report). I don't remember exactly what the error was, but it looks like i fixed it with...
sudo apt-get update
sudo apt-get dist-upgrade
sudo dpkg --configure -a
Then i went into the drivers settings and disabled third party drivers.
It was working fine until yesterday, when it started freezing again. It's no longer giving me the internal error...but the freezing happens periodically.
