Lightdm doesnt recognize password after computer has been asleep

cpdf98 · 2023-03-06 20:41:56

This started a few months ago. If my computer has been locked for a while and/or it goes into sleep mode after being left idle, then when i try to log back in it wont recognize the password. It will let me type it in just fine, but it will say the password is incorrect. From that point I have to restart my computer and only then will it recognize the password.

I have since distro hopped to see if the problem would persist on other distros, and I noticed the same issue would happen on specifically arch-based distributions. I have tried vanilla arch, endeavourOS, and manjaro and each one had that problem. I did not have the problem happen to me when using mint however. I highly doubt if this is relevant but i use cinnamon as my DE. I have not tried using other desktop environments but I doubt that would change anything.

Anyone else encountered this and know how to solve it?

Maybe a stupid response, but always worth checking.
Do you use a non-QWERTY key-layout ? You could have a misconfiguration somehow on your keymap.

Maybe you were saying that the layout was OK, in that case sorry for the obvious answer.

cpdf98 · 2023-03-06 21:03:43

I never touched the key layout in any distro i used, so they would all be the standard US layout

Set the password to something layout-safe ("12345") and see whether you can reproduce the problem w/ that.
Condition and symptoms indeed very much suggest that this is the problem.

Tried that. It still wouldnt recognize the password

Please post a complete system journal for a boot covering this. Eg. for the previous one:

sudo journalctl -b -1 | curl -F 'file=@-' 0x0.st

The locker probably uses, but is technically not lightdm and it might be interesting to see what pam is complaining.

You may also not have to reboot, zapping the server ( https://wiki.archlinux.org/title/Xorg/K … +Backspace ) or heading to a different VT and killing it (ctrl+alt+f3, can you log in there?) might do as well (nb. that you'll still lose your session in either case)

(readded so others can better find this)

sudo journalctl -b -1

and add this line at the top:

Do you understand what that does?
You basically just removed all restrictions from sudo.
=> Don't. This is a terrible idea.

Also I don't see how pam_sudo would affect lightdm or the cinnamon-screensaver.
Please post your journal, see #6

Update: Nevermind, that last hack doesn't work and is reproducible: When I go afk, I turn off my S95B OLED TV as monitor by pressing the off button on its remote and when I come back, lightdm greeter says wrong password. Changing the greeter from `lightdm-gtk-greeter` to `lightdm-slick-greeter` didn't help. My issue might be related to https://bbs.archlinux.org/viewtopic.php?id=279082. The last hack might or might not work when I don't turn off the TV. I'm gonna test that.

Stop messing around w/ pam_permit.so - it's a stupid idea and will only occlude the actual situation.

You can try to disable pam_homed.so - notably if you don't use systemd-homed, https://bbs.archlinux.org/viewtopic.php … 1#p2065201

Other than that, keep a rootshell open and check the condition of "faillock" and whether releasing the lock helps, https://wiki.archlinux.org/title/Securi … n_attempts

onetimehelper · 2023-04-29 17:05:42

Yes, I don't like this hack either. I did further testing: removed the insecurity line, restarted, went afk, and consciously didn't turn off my S95B TV and can still log-in. Not sure how long I'd need to be afk for it eventually to occur again, but so far so good [in getting closer to what's causing the bug]. I will test with being afk longer later.

I will try your workaround suggestions later as I would like to turn off my TV when afk.

The account is locked due to 3 failed logins.

appears as soon as when I'm back from afk, not trying to login into the greeter, but change to tty2 and just typing the username [so it's clearly not caused by me].

That's faillock, "deny = 0" is a workaround that more or less disables faillock.
Do you maybe use sudo in some cronjob/script?

That's faillock, "deny = 0" is a workaround that more or less disables faillock.

Changing `unlock_time = 10` in `/etc/security/faillock.conf` works. I don't want `deny = 0` as this looks like it could allow to brute-force a password.

Do you maybe use sudo in some cronjob/script?

I would be super aware if I had such script, but I did take a look at the following for what it's worth and nothing's there:

$ grep -rI -m 1 "sudo" /usr/lib/systemd/
/usr/lib/systemd/system/sudo_logsrvd.service:Documentation=man:sudo_logsrvd(8) man:sudo_logsrvd.conf(5)
$

There where 3 failed attempts at 10:33:36, 10:34:06 and 10:35:54 - was that you trying to enter your password?
Stupid question: is you password qwerty-safe? What if you change it to "12345"?

May be so, because this fixed it for him:

But switching DE entirely is not what I will do, `unlock_time = 10` exists for me. (I don't press the ESC key at all like he mentions)

Looks like it's already u+s: before:

$ stat -c "%a %A %U:%G" /usr/bin/unix_chkpwd
6755 -rwsr-sr-x root:root
$ stat -c "%a %A %U:%G" /usr/sbin/unix_chkpwd
6755 -rwsr-sr-x root:root

After `sudo chmod u+s /sbin/unix_chkpwd`:

6755 -rwsr-sr-x root:root

`shadow` group doesn't exist for me when I tried `sudo chown root:shadow /sbin/unix_chkpwd`. Maybe Arch handles it differently.

It's happening automatically and is why I started posting here. If it was me/anyone, I would complain why it didn't lock after 3 failed login attempts (3 is a good default for me, I don't need 10)

Yes, my password is qwerty-safe.

That's sacry. The failed unlocks happen 30 and 108 seconds apart, what doesn't look automated.

If my computer has been locked for a while and/or it goes into sleep mode after being left idle, then when i try to log back in

1. does anybody else have physical access to the system (incl. kids or cats)?
2. Can you detach the keyboard? Does that prevent the problem?
3. If you reaise the faillock threshold, does a pattern emerge in the frequency of the failed attempts?

Scary in the sense that it's simply a bug because it wasn't happening before and, of course, no, there's nobody that could have pressed it. (I can go afk being next to my keyboard). Started happening like 1-3 months ago, may even 1-2.

To 1. Nope
To 2. I will test that later and edit this or in further reply.
To 3.Raised to 10 and commented out `unlock_time`:

$ grep "deny\|unlock_time" /etc/security/faillock.conf

Interestingly, when I came back I was not locked out despite 12 counts of "auth could not identify password".

There're at least 18 minutes delay between the 10 fails, so the cooldown kicked in and reset the faillock.
The delay looks all over the place, there's probably spurious input.

not sure what you mean but :minutes:seconds

Well, yeah. Theoretically the hours could have changed (which under different circumstances would have been relevant)

onetimehelper · 2023-05-02 13:11:58

Is there a way to change the cinnamon-screensaver without removed Cinnamon?

I going to try a different user to see if any of my settings are causing it. I may also try a different DE just to see if it's cinnamon-screensaver. But first that keyboard disconnecting thing.

https://askubuntu.com/questions/356992/ … ock-screen
No idea whether that's still valid.

You can install xscreensaver or use xautolock w/ i3lock or slock or whatever else you want, but if this is spurious input, it might affect those lockers as well.

Created a new user, installed `gconf-editor` set `disable_lock_screen` to `true`, under both, gnome and cinnamon, but still happening.

Detaching the keyboard also doesn't work.
I installed `xfce4` (selected all packages, but had to manually install `xfce4-screensaver`), run xfce4-screensaver, just to see if it's maybe cinnamon-screensaver related and there it works/I can login after being afk.

Workaround
Since removing cinnamon-screensaver (pacman -Rdd cinnamon-screensaver) doesn't work because after reboot Cinnamon can't be loaded, what works is to go to org.cinnamon.desktop.screensaver and toggle `idle-activation-enabled` to `false`. Cinnamon's screensaver GUI also has an option to never activate the screensaver. Then I installed xscreensaver, reset faillock.conf:
```
grep "deny\|unlock_time" /etc/security/faillock.conf
#deny = 10
#unlock_time = 10
```
and it works. So it may or may not be a cinnamon-screensaver exclusive issue.

I haven't found yet how to change to xscreensaver when the shortcut Ctrl + Alt + l is pressed, so a different shortcut for xscreensaver may be used instead.
