xfce-power-manager does't lock screen with slock on suspend/lid close

edit: was xfce-power-manager performs no action on lid close/open, see from post #2 onward

edit2: was xfce-power-manager does not lock screen on suspend via lid close/open, see post #6

edit3: TL;DR:
Quick fix

$ xfconf-query -c xfce4-power-manager -p /xfce4-power-manager/logind-handle-lid-switch -s false
$ pacman -R xscreensaver

Hi, I've been trying to have my screen locked using slock on suspend induced by lid close using xfce's power management but so far I was unsuccessful.

I've disabled systemd power keys handling by setting almost all power-related options to ignore in /etc/systemd/logind.conf and now xfce power manager works in all instances except lid close, which seems to be fully ignored - the screen doesn't even get blanked. The acpi event occurs (checked that with acpi_listen) but there are no events visible in xev (should there be anything?)

I'm unable to produce any useful logs and I don't know what else to do except giving systemd the power control back. But that doesn't work for me either as I want to have my laptop both suspended AND locked when the lid is closed but with systemd I'm forced (among other things) to choose between the two.

What's next to check?

-m.

Hi, I think this command can be useful for you:

xfconf-query -c xfce4-power-manager -p /xfce4-power-manager/logind-handle-lid-switch -s false

Re: xfce-power-manager does't lock screen with slock on suspend/lid close

Thanks, I somehow missed that wiki entry though I'd swear I read that page at least twice smile

Anyway, it only helps a little - now lid close triggers suspend via xfce-power-manager but the screen still doesn't get locked. It is, however, locked when I suspend the laptop via power menu (i.e. clicking the "suspend" icon).

Seems like a bug to me. What do you guys think?

-m.

Re: xfce-power-manager does't lock screen with slock on suspend/lid close

Make sure you also have Settings Manager > Session and Startup > Advanced > "Lock screen before sleep" enabled.


If that doesn't make a difference, can you post back your xfce4-power-manager's current settings:

xfconf-query -c xfce4-power-manager -lv

...as well as the contents of /etc/systemd/logind.conf?


Anf if you want to debug what is happening with xfce4-power-manager, you can first quit the running process:

xfce4-power-manager -q

...and then run it in debug mode:

xfce4-power-manager --no-daemon --debug

Apparently power manager tries to communicate with xscreensaver, presumably to use it as a screen locker. I was under the impression that power manager (and other XFCE tools) use `xflock4` which support `slock` which I use for screen locking.

I don't use xscreensaver but I started it to see if it makes a difference. It did, about a second to resume `xscreensaver` is started in lock mode. The problem is that the desktop is fully visible and operable during that second. It appears the xscreensaver method is somehow hardcoded to lid suspend handling in xfce power manager. Still seems like a bug to me.

Re: xfce-power-manager does't lock screen with slock on suspend/lid close

The problem is that the desktop is fully visible and operable during that second.

To fix this issue, uncheck "Fade to black when blanking" on the Advanced tab in the xscreensaver preferences screen.

Apparently power manager tries to communicate with xscreensaver, presumably to use it as a screen locker. I was under the impression that power manager (and other XFCE tools) use `xflock4` which support `slock` which I use for screen locking.

If you look at the contents of the xflock4 script, you'll see that it will use xscreensaver or gnome-screensaver if their executables are installed. Otherwise, it will use xlock or slock. If you want to use slock, you will need to uninstall the other packages.

Re: xfce-power-manager does't lock screen with slock on suspend/lid close

You're right, removing xscreensaver helped!

I completely forgot I even had it installed before.

Thanks all, now it works. It's quirky but it works.

Re: xfce-power-manager does't lock screen with slock on suspend/lid close

I have the same issue, but none of the fixes work for me.
I can configure the power manager to either lock the screeen or suspend, but not lock and suspend.
I currently use xflock4 -> cinnamon-lock with this fix. xflock4 works fine, suspending from the action button does in fact suspend&lock.

I have no xscreensaver installed.

I use a systemd sleep-hook now, seems to work satisfactory.
