Question: delay or prevent login for an short period after locking screen

[Sylvain303]

I'm programming a sort of "go away from your computer" program. https://github.com/Sylvain303/timesup

I'm developing it for myself to make some forced breaks. I'm asking if I could lock the computer for a short period, say 5 min, with impossible to login. (yes of course some backdoor would be possible, console login for example).

Could also be solved by #71, by relocking immediately the computer.

Is there some possible way to not pop the lightdm login prompt or some other temporary deny behavior?

Light-locker doesn't have that intent. And will spawn the greeter when it locks. What you could do is add a unlock ignore timer. During this timer light-locker should ignore the unlock calls from LightDM and it should send you back to the greeter.

Maybe LightDM support temporary lock out. LightDM uses PAM, I'm not that familiar with PAM, but it might be able to do this. Also PAM should be able to print a message to the greeter explaining there is currently a lock out period.
