I seem to remember it used to be possible to
login via a GUI terminal. This was useful if (e.g.) you added yourself to a new group and want to use those privileges without stopping X to log in normally (since acquiring the new group requires a login).1 You can, of course, switch to a different VT, but this can be a hassle particularly if what you want to do requires an X display.
But on my current Fedora 20 w/ kernel 3.11,
login just hangs indefinitely. In the system logs:
login: FATAL: /dev/pts/3: change permissions failed: Operation not permitted
How can I get around this?
1. As it turns out you can get around all that by via
su youself, which performs a login...
