Which mode does the second server restore? It didn't save
a text mode if it didn't start in one. If you quit the first
server and then quit the second you restore a graphics mode.
Also, how does the first server know that it's not supposed restore
the text mode on this particular VT switch. Note that if it switches
to another VT, where there isn't an X server, it's expected to
restore a text mode in that case. This is not a problem that
can be solved correctly.
