No, Gnome does not, by default, show a console window. Many GUI based
users like me, coming from Windows a couple of years ago, prefer to
remain GUI based. I don't open termainals except to build kernels and
do system admin stuff. Most all of my day to day like is spent in the
GUI or in graphical applications. I move files, change permissions,
etc., in GUI apps, at least most of the time. I know that's going to
be pretty foreign to many old timers here, and that's cool, but I'm
just saying that this is the way it is for me.
Please note that I didn't say the info wasn't available. The info is
available in dmesg and I know to go look there. The point I was making
is that as a user I get no specific GUI level messages about this sort
of problem like I do in Windows and I think as more Windows folks come
to Linux there will be times they do not know what's going on.

Yes, I understand that. As I said in my first post, I think it would
be quite difficult to guarantee that every GUI environment running
under a Linux kernel handle stuff like this. I think it's enough that
the kernel makes the message available to the GUI developers. I would
hope that one day the GUI developers see the value of messages like
this from a user POV. To often the developers don't see things the way
new users see (or don't see!) things so the learning curve is pretty
steep.
Maybe one thing kernel messages could do is identify which ones really
should be driven up to the user level, if possible. I wouldn't have a
clue what to do for someone not using a GUI, but getting a dialog
based message about a system hardware problem seems pretty freindly to
a user like me.
Thanks,
Mark
