Screen Lock - Timeout

[sa0sin]

Hi,

Would like to know if it is possible and how to reduce timeout of unlocking dialog box when screen is locked ?

At the moment, when screen is locked through Super+L, there is a dialog box waiting for the password ...
It seems it waits 60 seconds (?) before issuing "Time has expired." and hiding the dialog until new mouse movement or keypressed ...
It's this I would like to reduce to 10 or 20 seconds only ...

Thanks in advance,
Regards.
