Fedora 37: Gnome 43: screensaver: How to lock screen from command line

[Dario Lesca]

I want start screen saver and lock screen from command line.

What is the new method into Gnome 43, since "gnome-screensaver-command
-l" no longer exists?

Thanks

[Dario Lesca]

Found it, by myself

# Lock
dbus-send --session --dest=org.gnome.ScreenSaver --type=method_call --print-reply --reply-timeout=20000 /org/gnome/ScreenSaver org.gnome.ScreenSaver.SetActive boolean:true

# Unlock
dbus-send --session --dest=org.gnome.ScreenSaver --type=method_call --print-reply --reply-timeout=20000 /org/gnome/ScreenSaver org.gnome.ScreenSaver.SetActive boolean:false

This appears to be Gnome-specific. Presumably equivalents exist for
those of us who use other DEs, but it would be interesting if a generic
solution existed.

Would those other desktop environments be using gnome-screensaver?

I'm looking for a gnome solution and what i found it's the only
existing one.

Other desktops each have their own screensaver manager[1]

I guess what I'm asking is if there's a standard (XDG) way to invoke a
screensaver.

Not sure if this is a "standard (XDG) way", but I'm running i3lock:
https://i3wm.org/i3lock/

Simple and efficient.
https://linuxcommandlibrary.com/man/i3lock

My environment:

% env | egrep -i 'n__desktop|session=|ssion_t|xdm'
DESKTOP_SESSION=i3
DM_CONTROL=/run/xdmctl
XDG_SESSION_TYPE=x11
XDM_MANAGED=method=classic

% loginctl session-status | grep Servic[e]
     Service: kdm; type x11; class user

HTH,
Wolfgang

Hi,

I use slock. It is lightweight, and does not get in the way (as they like to say). It is part of the suckless tools (www.suckless.org).

Thanks,
Ranjan

Interesting, or should I say really weird, that it's *default* blank
screen is white (according to that page).  What a way to prematurely
age a screen!

Maybe that's s subtle way to encourage you to change it :-)

Yes, i3lock and slock start a lock screen.

But not start the standard Gnome lock screen.

All other D.E. have their own screen locker, not Gnome, This is a
strange thing.

Now I have wrote a shell script with the dbus-send previous command
inside that do this job

Thanks

Not quite the same. A screensaver won't necessarily lock the session.
