XFCE has some sort of double lockscreen

Hi, I’m using Manjaro XFCE as the name implies with the lightdm display manager and the webkit2 greeter, although the greeter seems to be irrelevant since the problem was present on the default one too. This is the thing:

After leaving my computer unused for some minutes, it locks itself and goes to the login screen, perfectly normal stuff, this is something I want it to do, no issue there. However, one would expect that to turn on the screen and be able to login all you have to do is move the mouse, or press a button or something, well this kinda works, but this passes one barrier, of which there’s two.

When you move your mouse or give any sort of input to the machine to wake it up, it sort of flashes and I can see the mouse for a bit, but it doesn’t actually show the loging screen, you have to give it input another time for it to actually show it. This isn’t really a big deal as you can imagine, but it is somewhat annoying.

It’s worth noting that this appears to happen only if the computer locks by itself (so, by timeout) instead of manually. Manually locking the PC makes it wake up with a single input as expected.

What if you lock it manually then wait for the monitor to enter standby?

Hi, sorry for the late response, I forgot to test this every time lol. Anyways if I manually lock it and then wait (I waited about 10 mins) it still works as expected, one single input shows the lockscreen, as oposed to 2. So… I guess the timeout command is different to the one that triggers when I press the lock button, and that I should change that. Right?

It should be the same command. This can be a bug in XFCE. You can do the following:

Right after booting, lock the screen manually and then unlock it. Then wait until it locks by timeout and then unlock it. Then type journalctl -b > ~/log and post it in pastebin or something. Then post the link here. Maybe we’ll be able to see something.

Btw I just checked and the command that runs when I lock the screen is xflock4, idk if you know which one runs by timeout.

If it’s XFCE locking the screen, I’m pretty sure the command is the same.

Ok I’m going to test with this configuration (it was on 10, 10 and 15 before)

Also I noted that despite having the config here set to just turn off the display when i close the lid, it actually locks the machine… which is kinda weird and annoying ngl.

Ok here it is, I tested with the three times. 1 minute, 2 minutes and three minutes. At the 1 minute mark, where it says to just “blank the screen” it acted kind of weird, I moved my mouse once and it didn’t show the desktop but kind of flashed the screen, I moved it again and still nothing, I had to give actual keyboard input to get it to wake up and I didn’t need to log in, it just unlocked the screen.

At the 2 minute mark it happened what I describe on the post, one mouse input makes it flash but does nothing, and the second input gets me to the lock screen.

The three minute mark acted the same as the previous one.

Manually locking the screen, once again, lets me resume with a single mouse movement and asking for my password, of course.

Here’s the log: https://we.tl/t-4Ln10jAB5U

I can confirm this and other weird behaviors in xfce on Manjaro (but also on vanilla arch and xubuntu). The problems get massively worse, when you use at least two displays. Then the displays turn off after a while but directly turn back on and stay blanked but never turn off again.
These problems with xfce have driven me so bonkers in the last 5+ years (I think they roughly started when everybody started using systemd - I think I got a decent screensaver setup working in xfce once on void linux with slock) that I started using kde plasma in parallel which works regarding screensaver/screenlock and inhibiting even on multi-monitor setups flawlessly (but has lots of other bugs regarding panels and desktop backgrounds that makes the rest in kde much more painful than using xfce).

I have tried using light-locker and xfce4-screensaver each alone and even in combination (that one leads usually to the behavior described by the original post here).
It would be nice if we could track down these problems here in the Manjaro community.

So as tips to @tralph, I would suggest, first check which screensaver you are actually using in xfce. Often, both light-locker AND xfce4-scrensaver are running. I think the preferred one in xfce is nowadays xfce4-screensaver - but that one seems to be not playing nice with multiple monitor setups. light-locker alone has sometimes also the double login effect and tends to completely eat my keyboard so that the only way to login is via console and killing light-locker.

So if you @tralph3 could check on results with different screensavers and also report if your screens really switch off, maybe we can track the problem down a bit more here.

Regarding the lid-closing problem, this is thanks to systemd overriding xfce’s setting. You can ignore the lid-closing in /etc/systemd/logind.conf (make sure to set HandleLidSwitch=ignore) -> this will make the xfce settings regarding lid work.

Another remark:
I see the same issues in all systems using lightdm (mainly also Mate and Cinnamon) - so I assume the problem is somewhere in the interplay of systemd/lightdm/light-locker and other involved screensavers.

I am currently in kde as I need to get some work done, but I will try to get some log traces of locking to share here soon.

Thanks for the tips and the dedication to try to get to the bottom of this. Seems that systemd = bad was true after all haha (jk). Anyway, while I do have light-locker installed, I don’t have xfce4-screensaver so the theory that both are running at the same time doesn’t seem to be true.

Any idea on how I could check what runs when the screen gets locked by timeout? I can easily enough see what runs when I lock it myself because it’s in the hotkeys menu (which is xflock4 btw) and that seems to have no problems.

Also, thanks for giving me tips on how to solve the lid problem, but I don’t have the file you’re telling me to check, nor anything similar really.

I installed KDE the other day to test it out, haven’t really configured it yet for usage because I’ve been busy, but I’ll get to it and report to see if I encounter similar issues there.

Sorry the file is /etc/systemd/logind.conf - will fix it in my answer above. Let’s not bash too much on systemd here - there are other threads for doing that :wink: It might be also that I just don’t understand the interconnectivity of systemd, logind, and light-locker/lightdm and sombody else totally can see the problem in your log directly (and hopefully help us both).

Regarding what runs - I think doing the log-trace as described above by @mbb might yield something - I am just taking a look at your log - I hope somebody else sees more.

Maybe you can try to uninstall light-locker and install xfce4-screensaver instead (and logout or reboot after that) - does that change the behavior for you to the better or worse? Might have to reconfigure the settings once more too after that.

Can’t see anything suspicious in your log (was searching for locker, but only single mentions) - but also not sure what I am looking for - maybe someone with a bit more expertise can take a look?

Have you installed any other desktop environment in parallel? Cinnamon for example?

Doesn’t sound like @tralph3 has. I have tested various de switches but usually have started with vanilla Manjaro (or earlier on xubuntu) - however my current desktop started with a manjaro kde edition - though using my old home directory - so still having fragments of xfce configuration files of my main user in there (though I did axe the panel config file several times). My main Desktop does behave worst when trying lightdm based de’s (yes I switch the display manager between tests and make sure residue processes from kde or other de’s are killed) - especially in recent experiments, but very sure I had the (double) unlocking and freezing problems also on vanilla manjaro - that was my main incentive on starting de hopping after being a happy xfce user for years.

Yes, I also tested gnome, cinnamon, and mate (and currently mainly running kde) - gnome and kde handling screen locking correctly, mate showing exactly the same problems as xfce and cinnamon I didn’t explicitly test for screen locking - however not my cup of tea on a multi-monitor setup.

Anybody out there with a working screensaver in xfce (in regards of locking and turning off screens when no inhibiting application is running - or fullscreen workaround) on a multi monitor setup?
My main testing machines (both multi monitor setups) are a ryzen 7 1700 desktop with 32GB and Vega 56 gpu + a quadcore t440p with 16GB and Nvidia gpu.

I will try now to use xfce with gdm and gnome screensaver on my desktop and see how that behaves.

Running gdm and gnome-screensaver with xfce with settings 1 min blank and 2min sleep and 3min switch off has an interesting effect (same thing happens when setting to never, never, 1min):

After waiting one minute all my screens (3 monitor setup) turn off after about 10s after that all screen turn on again - no lock happened.

journalctl -f during that time shows this:

moving on to test lightdm + light-locker…

And with lightdm and light-locker things are getting really weird.
Independent of what I set in terms of timings in the xfce4 display power options, my screens all turn off (even if they are “just” supposed to blank) and directly wake up again. Depending on if I set in power manager security settings “automatically lock session” when screensaver is deactivated or activated this sleep and wakeupcycle continues forever, or works right from the moment that light-locker seems to take over. So as soon as I have seen the light-locker unlock box once the screens can fall truly asleep (and turn off). I will see if I can live with the setting “when screensaver is activated” - and have a one time wakeup after screens are turning off.

In this small testing series, I couldn’t reproduce the double-login problem from teh previous author, but will soon contine with some tests on my laptop.

Here is the full log when Display power setting are set to never, never,1 min and security to “when screensaver is activated”, 10s delay
(With a 10s delay the re-wakeup is barely noticable).

And a closing word on running xfce with lightdm, without light-locker and with xfce4-screensaver:
My displays turn off quickly but then turn on and show the screen saver and never turn off again. Things seem to lock correctly and I can unlock well. But no correct display turning off. Just light-locker seems to be able to correctly turn off displays.
Will open a new thread for that.

I had similar behavior when I tried using light-locker instead of xfce4-screensaver. I was ultimately trying to use xscreensaver, but only for screensavers without locking the screen. And then I would use light-locker to lock the screen… but I too had weird behavior. I wound up removing xscreensaver and light-locker and stuck with xfce4-screensaver as the only screen locker. This works fine for me, but I’m missing the Matrix screensavers. :smile:
