Hello,

First, thanks to everyone for the responses.  My followup:

OK, as others have pointed out, the VT system should just apply to the 
primary console display.  That still leaves me with a few issues:

1) If I switch VTs, sometimes GDM spawns a third X process (:2), using the 
primary .display file.  It is as if X respawns prematurely.  One time I 
had three Xs going on the primary display, on VTs 7, 8 and 9.

2) If switch VT to a text console and back to X, for some reason X on the 
primary display starts accepting input from both keyboards and mice.  The 
only "Device reopened" messages in Xorg.log refer to the desired primary 
input devices, so I have no idea why this is happening.

3) I need to figure out how to tell the kernel to ignore input from the 
secondary keyboard and mouse, for the case that I have a text console on 
the primary display.

4) I still have the problem that logging out dumps me at VT1 instead of 
the respawned X.  I'm not actually clear on the timing of the X 
respawning, it seems like it respawns if I switch VTs (e.g. if I switch to 
VT2 from VT1, it respawns and switches VTs for me).

Neither of these had any effect.  I still don't get any vtX option on the 
command line as reported by ps.  I seem to recall the Case2 testing files 
did work as far as the vt command line option.  I also realized that I 
don't actually want my secondary display to be on a different VT from the 
primary; if it were set up that way, only one of them would be running at 
once, depending on which VT is active.

Is there an alternative to gdm-simple-greeter I could use?

Well, I tried the following, not sure if it works yet:

  gconftool-2 --config-source=xml:readwrite:/var/lib/gdm/.gconf --set /desktop/gnome/sound/event_sounds --type bool false

Also, I notice that gdm is spawning an instance of pulseaudio, I'm not 
sure where that happens and if I can disable it.

No, I can use tab, that is an OK workaround.  I would just prefer a 
greeter that starts off with a "Username:" prompt.

Thanks, Wayne Whitney
