Well, as I already said in my previous mail (using deallocvt there), it says busy... I started on a fresh booted system, GDM running (on vt7), switched back to vt1 and logged in as root: root@darkside:~# deallocvt 7 VT_DISALLOCATE: Device or resource busy deallocvt: could not deallocate console 7 root@darkside:~# /tmp/vtmap tty1 busy tty2 busy tty3 busy tty4 busy tty5 busy tty6 busy tty7 busy tty8 free tty9 free tty10 free tty11 free root@darkside:~# /etc/init.d/gdm3 stop Stopping GNOME Display Manager: gdm3. root@darkside:~# /tmp/vtmap tty1 busy tty2 busy tty3 busy tty4 busy tty5 busy tty6 busy tty7 busy tty8 free tty9 free tty10 free tty11 free root@darkside:~# deallocvt 7 VT_DISALLOCATE: Device or resource busy deallocvt: could not deallocate console 7 root@darkside:~# Before stopping GDM, tty7 is busy as expected.

I believe to remember for such permanent VT allocation a while ago when I didn't use any display manager at all (but startx and FVWM as window manager) triggered by running some Gnome application(s). I just cannot currently find such an application that would trigger it. regards Mario -- It is a capital mistake to theorize before one has data.
