Yes, I am aware of this this this and this answer.
Still, I can't find the log information (the log lines I see when pressing ESC during splash screen. For example ‘stopped Target User and Group Name Lookups.’ ...) in any of the possible suspects in var/logs.
I.e. by looking at the most recently changed files: (my shutdown was at 11:20h, thus only these files can possibly matter)
/var/log $ ll -tr | tail
-rw-r--r-- 1 root root 27K 2016-10-27 11:03 Xorg.0.log.old
-rw-rw-r-- 1 root utmp 0 2016-10-27 11:20 wtmp
-rw-r----- 1 syslog adm 0 2016-10-27 11:20 kern.log
-rw-r--r-- 1 root root 0 2016-10-27 11:20 boot.log
-rw-r--r-- 1 root root 0 2016-10-27 11:20 gpu-manager
-rw-r--r-- 1 root root 0 2016-10-27 11:21 gpu-manager.log
-rw-r----- 1 root adm 0 2016-10-27 11:21 apport.log
-rw-r--r-- 1 root root 0 2016-10-27 11:21 Xorg.0.log
-rw-r----- 1 syslog adm 3,0K 2016-10-27 11:21 auth.log
-rw-r----- 1 syslog adm 194 2016-10-27 11:21 syslog
Did things change? Do I have to enable (persistent) shutdown logging somewhere?
My shutdown did not fail, took 15-20 seconds and completed. (Multiple runs before I asked this question, naturally). If you wonder about the 0-bytes: Truncated (emptied) those log files before shutdown for simplicity.
