[Note] Ubuntu 20 screensaver

Ubuntu 20 has no screensaver by default.  It just put the monitor into sleep mode.


To install screensaver:

$ sudo apt-get install xscreensaver xscreensaver-data-extra xscreensaver-gl xscreensaver-gl-extra xscreensaver-screensaver-webcollage

Add this to start up app: xscreensaver -nosplash

Remove,

$ sudo apt-get remove xscreensaver-data-extra xscreensaver-data xscreensaver-gl-extra xscreensaver-gl xscreensaver-screensaver-webcollage xscreensaver


I only looked into screensaver as gnome builtin screen power off stopped working. Just remove & installing fixed the problem:

$ sudo apt-get remove gnome-screensaver
$ sudo apt-get install gnome-screensaver
