Maybe... It really depends on exactly what state X has left things in
when it crashed/hung.  If X crashes and catches the signals, it should
try to restore the console to a usable state.  If it is a gpu crash then
X may still be functioning, but hung on a lock.  In this case, you can
generally ssh in or get serial console.  It is also possible for
something entirely more evil to occur, such that things get hung with
interrupts disabled which results in a case where nothing but the power
button will remedy it.  In any case, if X isn't able to cleanly exit and
call LeaveVT, then your console is likely hosed.
