I've done 5 upgrades so far without any issues.  This is the first one 
that has a problem and after some experimenting it looks like the kernel 
is identifying both the analog and digital ports and making the digital 
display the primary.  I use a KVM switch and needless to say it's a 
royal pain to have to switch back and forth to accommodate this one 
host.  Like you I settled on using th3 previous perfectly working 7.3 
kernel, not optimum but it does work.

I've also decided to get a graphics card in lieu of the on-board 
graphics card in the hope that that will solve the issue with the 7.4 

Agreed you do get used to these upgrades working seamlessly and it's a 
bummer when occasionally things don't work out exactly as planned.


Unencumbered by the thought process.
