Howdy,

I did my updates.  Lots of smaller KDE packages this weekend. Anyway, I 
rebooted and still no console.  No errors in dmesg or messages either 
except for below.  I'm not sure if it matters.  I see a reply from Aho 
with a kernel command line to try.  Aho says he had the same issue due 
to Nvidia changing the drivers somehow.  As I mentioned before, most 
people likely don't use a console anymore. They may not even know how to 
get to it.  I'm going to add that and try it.  If it works, we'll talk 
about what that disables and if it will affect anything else or be 
phased out as a option in the future.  I need my console.  I don't like 
rebooting all the time.

What I found in dmesg.

Last line makes me wonder.  :/

Off to prep another try.

Thanks.
