Error switching between graphical and text logins

[Mike Klinke]

I need some help in order to determine where the fault is here; 
Kernel, Xorg, gmd, or .... Is this unique to my computer or are 
others seeing this too?


========= Problem ===============

Logging into init level 5 graphical login screen, 
open up a terminal session,
press:

 <CTRL><ALT><F1>

init level 3 login screen is displayed

press:

 <CTRL><ALT><F7>

Instead of being taken back to the terminal session I left, I am 
presented with a new init level 5 graphical login screen.  This is 
recorded in /var/log/messages:

 
gpm[2841]: *** info [mice.c(1766)]:

gpm[2841]: imps2: Auto-detected intellimouse PS/2
