My understanding is, that not
[weremouse at moonstudio ~]$ lsb_release -rc
Release: 16.04
Codename: xenial
[weremouse at moonstudio ~]$ man xorg.conf | grep blank -A2
sets the inactivity timeout for the blank phase of the screensaver. time is in minutes. This is equivalent to the Xorg server's -s flag, and the value can be changed at
run-time with xset(1). Default: 10 minutes.
[weremouse at moonstudio ~]$ cat /etc/X11/xorg.conf.d/disable-blanking.conf
Section "ServerFlags"
Option "BlankTime" "0"
Option "StandbyTime" "0"
Option "SuspendTime" "0"
Option "OffTime" "0"
EndSection
does affect a ssh terminal, see
