Subject: Unable to unlock xscreensaver in Xfce
Date: Wed, 13 Apr 2016 23:16:31 +0200

Hi!

I just installed the xscreensaver package in Xfce and added it to
autostart.  I also enabled the screen lock from the xscreensaver-demo
window.  Now, if I manually run xflock4 or leave the computer alone for
a couple of minutes the screensaver starts and when I move the mouse the
unlock box appears with this text:

XscreenSaver 5.35
My hostname
Authentication failed!
My username
[OK]

Any keyboard or mouse button input just closes the unlock box and the
screensaver resumes.  I'm able to escape, however, by pressing
ctrl+alt+F2 to open a new TTY from where it's possible to log in and
shut down the computer.

As Chris Webber mentioned on the mailing list (IIRC), you’ll also have
to enable xscreensaver in the OS config:

  (use-modules (gnu services xorg))

  (operating-system
    ;; …
    (services (cons (screen-locker-service "xscreensaver")
                    %desktop-services)))

Could you try and report back?

I guess we’ll enable it by default in %desktop-services.

Thanks,
Ludo’.

Will this be compatible with our desktop environments, xfce4 and gnome?

Yes (this service simply adds a PAM entry and a setuid binary.)

Danny, I tried your fix but it didn't work for me.  I was able to run,
as root, `guix pull` + `guix system reconfigure` and log back in, but
when I try to unlock the screen my user password is refused.

Hi,

weird. It works for me here. I did the same as you did. (although I'm using fluxbox)

What happens when you run 

   xlock 

manually?

Can you unlock the screen there?

(just to clarify: as your normal user)

Also, what does

   which xlock

say?

How about

    ls -l $(which xlock)

?

Hi!

This starts the screensaver and I'm now able to enter my password to
unlock.  The unlock screen looks a bit different though.

Just to be sure, are you saying that the unlocking works fine with that?

And what does

 ls -l /run/setuid-programs/xscreensaver

say?

And 

  ps -ef |grep xscreensaver

?

Oops, my bad: this should be

  (use-modules (gnu services xorg) (gnu packages xdisorg))

  (operating-system
    ;; …
    (services (cons (screen-locker-service xscreensaver)
                    %desktop-services)))

where ‘xscreensaver’ is a reference to the ‘xscreensaver’ variable
exported by the (gnu packages xdisorg) module.

Yes, but it doesn't work with Xfce's native screen locking program xflock4.

Ah, then what does

say?

Aha!

Add (screen-locker-service xfce4-session "xflock4") to your services in your guix config file.

This means:

(operating-system
 ......
 (services (cons* (screen-locker-service xfce4-session "xflock4") %desktop-services)))

Or add it to an existing "services" entry.

When I try to reconfigure with this I get:

Extend use-package-modules so that it contains xfce:

(use-package-modules xfce .....)

If you have no "use-package-modules" form, it's supposed to go at the toplevel.

>Do you mean as a replacement for "screen-locker-service xscreensaver" or an additional service?

I don't think it makes a difference. It should support multiple instances just fine.

Errr. Oops. Better not do what I said previously (at least not permanently).

Because of [1], that is maybe not the right fix (however, it should work).

Can you do

 $ cat $(which xflock4)

please?

It seems to be a wrapper that just uses other tools to do the actual locking. Which ones?

It might be that it doesn't find xscreensaver-common but does find gnome-screensaver-command in your profile. Either way it's using something to lock the screen which then won't be able to unlock.

Yes, it didn't work.  I got the same problem as before with an
automatic authentication failure.

Sure.  See the attached file.

To recap, when you call

Please try to call these manually (in that order) and stop at the first one that doesn't throw an error:

$ xscreensaver-command -lock
$ gnome-screensaver-command --lock
$ xlock -mode blank
$ slock

Which one was it?

(It will probably still be unable to unlock)

IIUC, xfce-lock uses one of the above lockers.  For them to work, and if
you want to be able to unlock your screen ;-), you need to make sure you
use ‘screen-locker-service’  for each of them.

So:

  (operating-system
    ;; …
    (services (cons (screen-locker-service xscreensaver)
                    %desktop-services)))

since ‘%desktop-services’ already takes care of slock and xlock.

Could you try and report back?  We’re getting there! :-)

This was my original configuration which didn't let me unlock if I had
locked with xflock4. Any other ideas?

Oh wait; since the command is called “xscreensaver-command”, not
“xscreensaver” (well in fact there are both), this should be:

  (cons (screen-locker-service xscreensaver "xscreensaver-command")
        %desktop-services)

Could you try this one?

Thanks for your patience.  :-)

It didn't work.  I got the same authentication error when tried to
unlock.

Is this also why i3lock can't be unlocked?

I am sad to learn that you had switched to another system.


Well, because it was tagged 'moreinfo' on Monday April, 18th 2016 --
almost 4 years ago -- and the last activity was on May, 23rd 2016; and
the user that reported the issue -- probably local to their own
configuration -- does not run Guix anymore; and because the screen
locking service seems working elsewhere, then I am closing this bug.


Fell free to reopen it if you hit it again.


All the best,
simon
