Created attachment 1508380 [details] dmidecode result 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 How reproducible: always 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 Actual results: after 20 minutes inactivity system shutdown Additional info: 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: $ dconf-editor org.gnome.desktop.session idle-delay 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?

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.
