[ubuntu-za] Spontaneous Logout in 14.04

[Robin Bownes]

Hi All,

I hope that someone can help. I've been using 14.04 (64bit) on my Dell 
Inspiron 7520 laptop for quite some time now, and all has been well. 
However, relatively recently - the past few weeks - the system 
spontaneously, and seemingly randomly logs me out. This has happened 
while doing several different things, so I've not been able to tie it to 
a specific activity.

I've tried Googling for an answer, but haven't come up with anything 
other than a few other people who also cannot find solutions for similar 
problems. (doesn't seem to be a direct hardware link)

Somewhere along the line, I was advised to run "dmesg| tail", which 
produced the following output, including the warning and advisory shown 
in red, below.

Any help appreciated. Please use single syllable words and short 
sentences. I'm not an expert. Thanks.

Robin
