When on GDM login screen, Ctrl+Alt+F3 ... F7 does not work. After logging into GNOME desktop, then Ctrl+Alt+F1 will bring me to GDM, F2 back to GNOME, and F3 to F7 to a TTY terminal.
But before I log into GNOME, I'm unable to switch to a terminal. Trying to do so even results in loosing my trackpad and no more control over the mouse pointer.
So are tty3 to tty7 (or more?) available when on GDM before logging into GNOME? If so, how to access them? If not, why, and how can I enable them?
