Hi. I installed kali5.2 (version 2019.3), but the duration from click 'shutdown' to poweroff completely takes more 1minute. about 1.5 to 2 minutes.
Before I used Kali4.19 (version 2019.2), at that time shutdowntime was about 10 to 20 seconds.

Why does shutdowntime longer at latest version??
I want to shorten shutdowntime, Please show me how to modify it.

Best regards;
