Recently I tried to switch to VT (console) and I couldn't - Ctrl+Alt+F1
didn't work (and they used to couple of weeks ago). I don't even know
where to look for the problem; xev detects KeyRelease XF86_Switch_VT_1
event, /etc/inittab contain getty respawns.
Oh, when I tried chvt 1 it responded:
Couldnt get a file descriptor referring to the console
