No console anymore. How to figure this out.

Howdy,

I did my updates earlier.  Usually I logout, go to boot runlevel and 
restart services if needed and then go back to default runlevel and 
login.  I noticed a couple weeks ago that I no longer get a console when 
I do a CTRL ALT F1.  My monitors turn off saying no signal.  At first, I 
did the sysrq thing.  Then it occurred to me that I should try CTRL ALT 
F7 and see if the GUI is still running.  It is.  So, at least I can log 
back in.

I've never ran into a situation where CTRL ALT F1 didn't give me a 
console.  I did check, agetty is running.  I even did a pkill so it 
would restart, still no console.  I have no idea where to go from here.  
In some 20 years of using Linux, I've never had a console not be there.  
This started about two weeks ago.  Maybe three.  I suspect a update but 
it could be that I either updated a config file or may have changed 
something not meaning to.

Anyone have ideas on what to check to fix this?

Thanks in advance.

Dale
