[Testing - Trixie] Xfce lock screen issue?

[kalle123]

At the moment I am preparing for the oncoming change to trixie from bookworm with 2 installations on my bookworm desktop.

- A trixie in a VBox
and a
- trixie on an external SSD connected USB 3.

Not using trixie for a certain time, I do get on both systems (VBox and USB 3) after 5 min al lock screen.

Please see attached pics.

4.jpg is my setting under different bookworm installations. 'Not activating Lock screen when system is going to sleep' prevented in bookworm this behavior, but not in trixie here.

Could someone here please check?

These don't seem to be the 4.20 screens that will go into Trixie.

There is no dedicated "security" tab anymore. Lock screen management was massively simplified and "Light Locker" was dropped. "lock-on-sleep" is now synchronized with xfce4-session and xfce4-screensaver.

Screen locking settings are now only handled by xfce4-screensaver to avoid conflicts. A button to open xfce4-screensaver-preferences was added:

https://xfce.org/about/tour

Is xfce4-screensaver part of the install? Is light-locker still there? Possibly Trixie is still in transition and this switch hasn't been completed yet.

I have a live image of Trixie XFCE and will investigate when I'm at the computer.

Thx. I'll wait and hopefully others do a short check too. Could be caused by the change from Xfce 4.18 to Xfce 4.20 or it could be a sheer Debian thing? If confirmed ....

Could then place a report at https://gitlab.xfce.org, but as we are on Debian, the prime address is a bug report.

I'm pretty sure it's an XFCE 4.20 thing, with 4.20 "dropping" Light Locker (see previous quote).

I've been testing Testing, and I can confirm that light-locker is installed, xfce4-screensaver isn't, and the screen is locked when "Put to sleep after" and "Switch off after" are ticked in the Display tab.

The system also attempts to suspend after a period with nothing ticked, and screen lock is attempted but fails (as it does in Bookworm), presumably due to the same issue.

I think the only way to change this behaviour would be to configure light-locker directly.

xfce4-screensaver has been added to Testing. I tried uninstalling light-locker and installing xfce4-screensaver and the extra options in the XFCE tour screenshots appeared. It didn't have any effect, probably because a reboot with changes would be needed, which isn't possible in a live image.

The XFCE tour says xfce4-screensaver is going to handle screen locking in 4.20. I don't know if Debian Testing will switch to xfce4-screensaver at some point. Probably worth checking if there is a bug report for this.

Another thing I can look at is the xfce4-session config file in Trixie to see what the lock command is now.

logoff/logon cycle?

Good idea! I'll try that.

We are approaching the release change in near future and for a then 'stable' release that seen behavior is NOT OK for the average desktop user, I think.

NOT ticking that box here should make things clear. NO LOCK SCREEN! Light Locker we have in bookworm and it works there as expected.

I don't have a problem writing a bug report, BUT on what package?

I would pick xfce4-power-manager

bookworm 4.18.1-1 did as supposed and trixie testing 4.20.0-1 does not. Let the developers have a look!

Absolutely it needs to be fixed.

The good news is everything seems to work with light-locker removed and xfce4-screensaver installed. (Logoff/Logon - hat tip to CwF).

Initially I set screen blank in the Display tab and the screen was locked after blanking Then I hit the "Screensaver management" button, and there is no locking when the screensaver is enabled and lock is not enabled.

I then went back to the Display tab and re-enabled blanking and the screen did not lock. The screensaver image did appear for a moment, but this could probably be avoided by setting the screensaver to blank screen.

I suppose the bug is in whatever package still has light-locker as a dependency and not xfce4-screensaver, as XFCE 4.20 cannot now change light-locker settings/

Bug report is out.

Made it in a hurry and I am not writing 3 reports a week, but I think this issue should be cleared before release.
Pointed to this thread here ....

I uninstalled light-locker and the problem is gone for me no more lock screen, all I setup is to turn off the monitor I don't suspend or anything like that but,
everything seems to be working as expected.

Hope this helps

Install xfce4-screensaver if you want to be able to change screen blanking, sleep and locking from XFCE. I'm trying it in Trixie and everything seems to work. Doesn't seem to have the suspend issue that has been present in XFCE for years. At least, I think I've tried every combination of blank/lock suspend/lock and haven't seen it yet. Also seems to be a lot quicker waking up the screen (the Intel issue?).

Thank you both for posting those ways, to circumvent that behavior. Is fine for testing, but for a trixie stable release the developers should look into this and don't have a user search the net for a solution ... Therefore a bug report and I hope this is solved in near future.

Light-locker is not part of Xfce but rather lightdm project. I'm not sure why the Debian Xfce folks package it in to the DE. xfce4-screensaver seems to work fine although I don't use it personally. I also don't let my laptop sleep/hibernate. If I do want to lock the screen I use dm-tool lock.I have it set as a command in the whiskermenu.
