Kevin or anyone who has a suggestion:

I tried the suggestion in the link you provided and it works ... as 
advertised (???). If I have logged in, enabling that setting does mean 
that crtl+alt+backspace will restart X and put me back at the login screen.

But it doesn't help in the one situation that I usually want to restart 
X. I turn on a machine but the KVM is pointing to another machine. When 
I am ready to use the machine that I have just powered up, the screen 
size settings are wonked and I want to crtl+alt+backspace to restart and 
get the screen size correct. In this case, it doesn't work.

 From what I can figure out, there is some part of the boot process that 
polls the monitor and, if it the KVM has it pointing elsewhere, it makes 
"worst-case default assumptions" since it doesn't see the monitor.

I am now assuming that the setting that I have made via the link's 
suggestion works once a login has occurred and all shell stuff has been 
resolved.

Is there a way to enable the key combination to work prior to logging 
in? I am certainly happier that I can at least login, kick it, and get 
settings back ... but that seems "wrong" since I don't think I really 
should be restarting X once logged in.

Thanks in advance,
Paul

ps: I am also looking into all the other suggestions made in this thread 
to see if I prefer any of the others, but figured I'd at least ask about 
this "almost what I want" solution.
