I don't really follow the Ubuntu all that much, looks like the box here
started with 12.04.4 and worked up to the 14.04.5 it was running before the
problem with the 16.04.1 upgrade. I guess it took all those updates before
without any problems, till now.
I don't use it for anything critical, mostly as a backup server running both
nfs and samba, but that stuff didn't work right under 16, mostly the nfs,
seemed like even with nothing mounting the drives, lockd kept crashing
causing the nfs server to go into a 90 second delay, totally usuable. The
video was tearing too, mostly when the mouse was moved around. I just use
the built-in ivybridge, no card but the point is, it didn't do it before.
The killer for me was I have an IR dongle on it for a remote, after the
upgrade just tapping one key on the remote was like smashing the key down,
it took it like 5 or 6 repeats.
Since all this stuff seemed kernel related or a broke library somewhere, it
just wasn't worth the effort to figure it out. A clean wipe and reinstall of
the 14, copy a few scripts back and everything was fine. I probably should
of tried it with a clean install of 16 but crap like this leaves a bad taste
in your mouth.
