Hi guys, I hope you're doing fine.

I would like to get some guidance/opinions regarding this subject. The default 
screensaver for xfce spin is xscreensaver that  I didn't like it. Reading about 
how to make it more appealing I found this:

https://www.jwz.org/xscreensaver/faq.html#toolkits
https://www.jwz.org/xscreensaver/toolkits.html

Which made me feel more fond to it, but I kept reading and found that 
light-locker can do the work without sacrificing (too much?) security.

That brings one of my questions, is light-locker secure enough to be a 
replacement for xscreensaver?

Then, I set up a VM to test this instructions regarding installing light-locker:

https://kororaproject.org/support/documentation/screen-locking-with-light-locker

which basically says:

        * sudo dnf install light-locker
        * sudo dnf remove xscreensaver*
        * reboot system

but they didn't work with this error

$ xflock4
Property "/general/LockCommand" does not exist on channel "xfce4-session".

Doing more research led me to this:

https://mail.xfce.org/pipermail/xfce-bugs/2015-April/006548.html

That adds this line '<property name="LockCommand" type="string" value=""/>' , 
without quotes, to the file 
/etc/xdg/xfce4/xfconf/xfce-perchannel-xml/xfce4-session.xml.
The patch is for xfce4-session 4.12.0 and the version installed is 
4.12.1-9.fc25. I checked the file in question and it doesn't have the line 
therefore I added to it.

Now, xflock4 doesn't show any error but the screen is not getting locked.  So, 
I kept researching and found this:

http://unix.stackexchange.com/questions/101806/why-doesnt-my-screen-lock-in-xfce

that recommends create the property for the 'gnome-screensaver'.

$ xfconf-query -c xfce4-session -p /general/LockCommand -s "dm-tool lock" 
--create -t string

after executing the above line, xflock4 works with light-locker.

Now I have some doubts if the procedure is fine or if there is a better way to 
achieve this? And regarding the line added, is this something that could be 
included in the system?

Thank you all for the help!
