Will attach output when I am back at the PC. Using ubuntu 18.04.1 Desktop

I have had ubuntu on this computer since 15.10 and always upgraded it 
and kept it up to date. This is the first problem I have had on it.

I have it set up as triple boot with Ubuntu openSUSE and Windows 7. 
OpenSUSE and windows 7 work fine still.
