Description of problem:
After 20 minutes of inactivity system automatically shutdown.
I have Fedora 29 MATE desktop (basic installation)
Version-Release number of selected component (if applicable):
Fedora 29; Mate 1.20.3
What I (unsuccessfully) tried:
System ---> Preferences ---> Hardware ---> Power Management
disable all power choices in [On AC Power|On Battery Power|General]
dconf-editor (and disable all suspicious switches)
systemctl mask sleep.target
systemctl mask suspend.target
after 20 minutes inactivity system shutdown
I have laptop in docking station (see my dmidecode) with closed lid.
There is no setting in power-manager which do power off the system.
There are only settings for suspend-to-ram or -disk.
Does the issue exists if you don't use the docking station?
I have found (ugly) workaround:
300 ---> 4000000000
Mate use same session name than Gnome for making it easier to interact with other programs.
But that means that there is a new setting in gnome which power off the system when session is inactive.
Or this is a bug?

Are you going to live that long :-), 126.83 years is a long time.
The culprit of unexpected power-off was 'vlc' with camera screen:
$ vlc -f 'rtmp://192.168.0.6/bcs/channel0_main.bcs?channel=0&stream=0&user=admin&password='
After several dozen minutes laptop shuts-down to prevent self-ignition.
Outside od docking station cooling is better, therefore worked without power-off.
Not a bug.
