Hi Izzy,

There's just one thing that kind of bothers me, though: with slimlock
it's possible to use an option (called 'tty_lock') which disables
switching to another virtual terminal while the screen is locked (using
VT_LOCKSWITCH).

I think this is a nice "security feature", if you wish. So, I was
wondering: first if this would be desirable in i3lock, and in that case
if it could be possible to add a similar option. It doesn't seem to be
_that_ difficult to implement, but unfortunately I don't know C, so
submitting a patch is out of the question.
Switching to a VT in itself is not a security issue since these are
protected by getty (or other software which asks you to login).

If you actually use the VTs and want to lock them, use different tools,
e.g. vlock.

i3lock is an X11 screen locker and I don’t want to extend its scope to
VTs.
