I've only seen this when X is running.  X can't be running.  It's not
sufficient to merely switch to a vt text terminal.  X must be stopped
entirely to release the graphics card to be able to switch.  You can
use DDIS to post a switch for when X restarts, but I've found this
isn't always as reliable. Thanks,
