I'm seeing the same thing, but (a) only after upgrading to hardy (so
feel free to tell me to file a new bug!), and (b) only from a logged-in
session; from gdm, I can switch VTs just fine. My specific symptom is
that it apparently tries to switch (the screen blanks) and then it looks
like X intercepts it and switches back before the VT gets a chance to
finish displaying. Interestingly, the focused window also seems to get
ButtonRelease events for all buttons - I happened to have a pterm
focused and its Ctrl-rightclick menu appeared after X regained control.

Enselic, does this match what you see? If it isn't, I'll file a new bug.

I'll attach my Xorg.0.log in a moment. The following text at the end of
Xorg.0.log appears during the VT switch attempt (as measured using 'tail
-f'):
