[Nut-upsuser] Shutdown problem with Geek Squad GS1285U

[Gary Redden]

I do not have enough knowledge of Linux to answer those questions. I am 
running Ubuntu desktop the GUI version so I must be running some nVidia 
driver. I run the GUI version so I can poke around faster. I have spent 
most of three weeks getting this far. I will continue to work on this 
but need to be pointed in the right direction. I have another project 
that needs most my attention for the next week(spec. for a fire truck 
for my volunteer fire department) but will work on this in my spare time.
