Help with XScreensaver and xss-lock

Hello! I have been analyzing the "List of applications" article and I
got to the Screen lockers section
(https://wiki.archlinux.org/index.php/Li … en_lockers),
and I decided to go for "XScreensaver" since it has a Wiki page and it's
the default on other distros. I also love the little whales and sharks

Now I have a few questions:

First and most important: How to set it up to lock the screen on
suspension and hibernation? I am using Xfce's power manager, and I have
installed xss-lock. Still suspending or hibernating doesn't lock the
screen. Do I have to do some extra configuration?

Secondly, the way I understand it, XScreensaver overrides my display power manager, so should I just disable it? Would this mean I can't
differenciate between power management on AC and on battery?

Thanks for the help!!

Re: Help with XScreensaver and xss-lock

Only using Xfce's power manager without xscreensaver and slock. Installed and config "slock" in xflock4:

https://git.xfce.org/xfce/xfce4-session … ts/xflock4

/usr/bin/xflock4:

Re: Help with XScreensaver and xss-lock

You say you've installed xss-lock but are you actually running it? You need to run the following: xss-lock -- xscreensaver-command -lock

Secondly, the way I understand it, XScreensaver overrides my display power manager

XScreenSaver will set the DPMS timeouts, yes. You can see what they are using the command xset -q
If you have another power manager installed then you may find that it will also try to set the DPMS timeouts. In that case, the timeouts will be set by the last program to start. Not an ideal state of affairs so, yes, you probably only want to start one or the other.

Would this mean I can't
differenciate between power management on AC and on battery?

Yes, XScreenSaver doesn't differentiate between the two.
