Xfce4-screensaver locker often no input

Hello,
I’d like to finally report an issue I’ve been having with my installs of Manjaro-XFCE.

When resuming from suspend, I get to the lock-screen. (provided by xfce4-screensaver-locker according to htop in a second session)

Often, here I can not enter my password directly, the password field is not clickable and I can not type in it.
Moving the mouse cursor over the text field, it even changes to the text selection cursor but clicking there does nothing.

In these cases I can log in by clicking the “switch user” button (or hitting Alt+B) and then logging in though lightdm-gtk-greeter, just as I would after a boot.

But sometimes, the lockscreen will not react to any inputs whatsoever.
The mouse cursor can always be moved but in this instance, I can not click anything.
The only thing left then is to CTRL+ALT+F3, log in and then reboot.
Of course I’ll then loose any unsaved progress.

As you can imagine, while the first one is a nuisance, the second one makes suspend practically unusable to me.

The issue is present on two separate installations of Manjaro on different Thinkpads (T440p and X380).
Both had been installed from manjaro-xfce-24.0.7-240821-linux69.iso, but upgrading to the current 24.2.1 didn’t help on either.

A fresh install of manjaro-xfce-24.2.1-241216-linux612.iso doesn’t have the same issue as far as I can tell, but I’d rather not reinstall the OS.

I tried to reinstall lightdm:

sudo pacman -S lightdm lightdm-gtk-greeter lightdm-gtk-greeter-settings

I also tried to reinstall xfce4-screensaver since that provides the locker.

On Arch, I can not replicate this behavior.

Might this be a default-configuration issue solved in later Manjaro releases?

Any help would be appreciated!

A reinstallation will not affect or change any configuration - if the existing configuration is different from the default, a .pacnew file might be created
as far as I understand:

pacman/Pacnew and Pacsave - ArchWiki

So if there are differences they should be easy to spot - by the mere existence of .pacnew files - and by comparing the contents.

You could also do a comparison of the files in the problematic machine with the one you freshly installed.

Thank you very much, didn’t know about pacsave files, makes sense.
I used pacdiff and the find on root but I was unable to find anything related.
Maybe someone with knowledge of the XFCE packages (e.g. one of the XFCE flavour maintainers) can chime in / enlighten me what changed since the versions above?

… and upon reboot it works? Reliably?

Perhaps the reboot is not needed - I have had similar problems with my Gnome VM.

CTRL+ALT+Fx takes you to a TTY - from there you can just go back to the TTY where your session is running.
You can cycle through the available TTY’s with:
ALT+left arrow or ALT+right arrow

… or
CTRL+ALT+F7 - to TTY 7 - which is where the Xfce session runs

This has often done the trick for me - it’s a thing you could try.

It’s not a solution, of course - but I do not have any advice on how to approach the real cause. :man_shrugging:

I only have a VM and have disabled the screen saver anyway.
