Yesterday I updated 21.04 to 21.10 and was looking at the terminal in the meanwhile when I noticed the installer had disabled the lockscreen. I’ve been unable to use it ever since. So far the following yielded no results:
- WIN + L;
- Setting up the blank time to 1 min and automatic lock screen delay to “Screen turns off” (the screen never turns off);
- Re-configuring the display manager and setting it to lightdm;
- Uninstalling gdm3.
The disable-lock-screen dconf setting in org.gnome.desktop.lockdown
is not enabled.
Journal logs after pressing WIN+L:
gsd-media-keys: Couldn’t lock screen: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.gnome.Shell.ScreenShield was not provided by any .service files
I’m out of ideas, thanks in advance for the help.
What is the output of
ps -ef | grep screensaver
1562 1321 0 18:54 ? 00:00:00 /usr/libexec/gsd-screensaver-proxy
3848 2396 0 19:01 pts/0 00:00:00 grep --color=auto screensaver
ps: added journal logs to main question
ok - gnome-screensaver isn’t running.
It should be autostarted via /etc/xdg/autostart/budgie-desktop-screensaver.desktop - look at the exec= line.
Have you got this?
have you got something in ~/.config/autostart that has a similar exec=gnome-screensaver value? Maybe that is disabling things.
using dconf-editor navigate to org.gnome.desktop.screensaver - use the three dots in the headerbar and choose “Reset visible keys” - this ensures the default screensaver values are being used
You should also reset the visible keys in org.gnome.desktop.lockdown
Update: without doing anything, this morning the screen turns off after specified time and lockscreen works. (Even after multiple restarts, the problem wasn’t being solved before).
It should be autostarted via /etc/xdg/autostart/budgie-desktop-screensaver.desktop - look at the exec= line.
Have you got this?
Yes, everything looks fine there.
have you got something in ~/.config/autostart that has a similar exec=gnome-screensaver value?
Nothing there that mentions gnome-screensaver.
I’ll see if the issue comes up again, hopefully not!
Cheers for the help
If the lockscreen appears then gnome-screensaver must be running. Check the process via ps -ef
As to the observation about turning off at a specified time … what do you mean - what time? On a specific interval? Does changing the settings - power blank screen value have any effect?
After restarting the lockscreen stopped working again – ps -ef confirms that gnome-screensaver is not running. No other changes were made since it worked; only power off and power on.
As for the other observation, I meant the screen turns off after the specified inactivity time.
Are you using slick-greeter for your login screen? GDM3 will not work with budgie anymore.
I’ve never actually fiddled with the login screen, so I’m guessing I’m on the default. I tried yesterday to reconfigure my display manager, (re)set it to lightdm. I then even completely removed gdm3.
When you login and check if gnome-screensaver is not running… what happens if you start gnome-screensaver from the command line?
I.e.
gnome-screensaver
I am wondering if you have some sort of race condition where gnome-screensaver is starting too soon. Maybe adding a delayed startup - say 10 seconds would be enough to have gnome-screensaver startup successfully.
gnome-screensave
r returns:
** (gnome-screensaver:12584): WARNING **: screensaver already running in this session
but then ps -ef | grep screensaver
shows that screensaver is not running.
WIN+L in fact is still not working.
hmm
have you got a file called /usr/share/gnome-shell/org.gnome.ScreenSaver
?
i.e. do you have both gnome-shell and budgie installed? I’m wondering if gnome-shell is interfering here.
I do have that file, this is its content:
imports.package.start({
name: 'gnome-shell',
prefix: '/usr',
libdir: '/usr/lib',
});
right - so gnome-shell is screwing up budgie here.
Does this work?
pkill -9 -f /usr/bin/gjs /usr/share/gnome-shell/org.gnome.ScreenSaver
Wait a couple of seconds then try running
gnome-screensaver
That allowed me to lock the screen with WIN+L
right … so its question of crafting a bash script now that can be autostarted.
It will need to test if gnome-screensaver is running
if not - run that pkill command above, sleep 5, followed by gnome-screensaver.

So this is what I came up with:
#!/bin/bash
if ps ax | grep -v grep | grep gnome-screensaver > /dev/null
then
echo "gnome-screensaver is not running"
echo "starting gnome-screensaver ..."
pkill -9 -f '/usr/bin/gjs /usr/share/gnome-shell/org.gnome.ScreenSaver'
sleep 3
gnome-screensaver
else
echo "gnome-screensaver already running"
exit
fi
Adding it to startup applications seems to be sufficient to get everything running the way it should.
Cheers for the help

pkill -9 -f /usr/bin/gjs /usr/share/gnome-shell/org.gnome.ScreenSaver
The two pkill commands should just be one as above.
Had to run them separately because your command returns this:
pkill: only one pattern can be provided
Try `pkill --help' for more information.
Ah … missing single quotes
pkill -9 -f '/usr/bin/gjs /usr/share/gnome-shell/org.gnome.ScreenSaver'
