[arch-general] I have to switch back to tty1 for systemd to shutdown the pc

hi all, Since latest update of gnome 3.4, I can't login through gdm because, then, I have no single glyph or font displayed on my desktop in menu or application (but not the qt ones) So, I found the work around to switch to tty2 and login and run startx and all is fine in my desktop. The fonts are back. No idea what this bug is about ! Anyway, my problem is: When I shutdown the PC from gnome desktop, I end up on tty2 console, and nothing is happening there i.e. no shutdown. I have to switch back manually to tty1 so that the shutdown procedure begins or continues. Any idea why systemd fails like that ? or gnome ?
