how to use layout.ensure_locked

[CRAG666]

By mistake, I pressed this function, but I did not know how to remove it, I literally had to restart to use the system again, would there be a chance to tell me how it works?

[jbuchermn]

Check the youtube video at 0:50 - this is what should happen. Can you describe what happens when you invoke that function?

[CRAG666]

That does not happen, it only blurs the screen, and you do not see the screen where it asks for the password

[jbuchermn]

Okay that‘s a bug. On the other issue you mention that you can unlock the screen - does the lockscreen ever show up?

Could you please post a minimal log and your config?

newm_log

[CRAG666]

The lock screen never appears

[CRAG666]

Is it something to do with the fact that I don't have alacritty installed and use kitty instead?

[jbuchermn]

Yes, you're right, that's part of the problem, the other is that panels.lock is not configured. This can be done easily by adapting

panels = {
'lock': {
        'cmd': 'alacritty -e newm-panel-basic lock',
        'w': 0.7,
        'h': 0.6,
        'corner_radius': 50,
    },
}

to kitty.

[CRAG666]

thank you, don't you think it would be useful to have an option called terminal?

[jbuchermn]

Does it work?

For newm itself such an option isn't necessary. The right way is to handle it via a variable in the config file, like you do. Probably I am going to include your config with some adjustments as new default config.

[CRAG666]

now it appears but typing my password just doesn't remove it

[CRAG666]

@jbuchermn I type my correct password and the lockscreen just won't remove

[jbuchermn]

Does it accept input when you type?

[CRAG666]

yes

[CRAG666]

but when I press enter the lockscreen is not removed

[jbuchermn]

Can you post a log? Passwords should not be logged, however best you check yourself.

[jbuchermn]

Plus: Does pam authentication work in a python shell?

import pam
p = pam.pam()
p.authenticate("user","password")

[CRAG666]

ok i just tested pam, and the output is True

[CRAG666]

In the lockscreen it only asks for my password, is it possible that my user is not the correct one?

[jbuchermn]

Okay that's good, pam works. Can you try adding some debug log to auth_backend.py to see if maybe the user is wrong, or sth similar?

[jbuchermn]

Please also check $HOME/.cache/newm_panel_log - does it look like this?

[CRAG666]

as I imagined I am using your username

[CRAG666]

How do I change the user: jonas to my user?

[jbuchermn]

Thanks a lot!

I just realized the user is actually hardcoded in newm_panel_basic. So this is definitely a bug and not something you can change yourself. I'll fix it

[jbuchermn]

Actually, the username is hardocded but overwritten if newm is able to find the current user (which always should be possible). The relevant lines are:

with open('/etc/passwd', 'r') as pwd:
    for user in pwd:
        u = user.split(":")
        if "nologin" not in u[6]:
            print([(u[0], int(u[2]), u[6], os.getuid())])

Could you run these in a python shell and verify that your user appears?

[CRAG666]

why not better ask an environment variable? I will try it anyway, although I still think that with the variable $ USER it would be solved

[CRAG666]

[('root', 0, '/bin/bash\n', 1000)] [('crag', 1000, '/bin/zsh\n', 1000)] [('git', 977, '/usr/bin/git-shell\n', 1000)] [('ntp', 87, '/bin/false\n', 1000)] [('greeter', 964, '/bin/bash\n', 1000)]

this is output

[jbuchermn]

Yeah, in this particular case you're right - $USER or whoami works just as well. The thing is, this does not work when using newm as a login manager, where we need all possible users for login. That's why newm uses /etc/passwd - let's see where the bug is first, then how to fix it.

[jbuchermn]

okay, thats the expected output suggesting no issues with using /etc/passwd - so I'll have to look elsewhere

[CRAG666]

@jbuchermn Do you use greetd? If so, could you show me your configuration file?

[jbuchermn]

Yes I do, there's some info on setting it up in the README. However, we should really get the lock screen working before you try newm with greetd. Otherwise you might not be able to log in at all.

[jbuchermn]

Could you update, retry and post both log files?

[CRAG666]

ok

[CRAG666]

The error persists

[jbuchermn]

Please post both log files

[CRAG666]

the newm_log?

[jbuchermn]

Yes, that's where the bug happens.

[CRAG666]

newm_log

[jbuchermn]

This is definitely a hard one to figure out... I still need more debug info. Can you update, rerun (also lock the screen) and again upload logs? Thank you

[CRAG666]

Ok

[CRAG666]

@jbuchermn This works and is great, Thanks, now before I close this, how do I open the newm launcher?

[jbuchermn]

That's interesting, not sure what was causing the bug... This whole websockets thing needs a rewrite in v0.3

Do you mean the app launcher? Actually since rofi works I have never bothered using the newm one and I'm going to drop it soon. Or do you mean login manger?

Try logging in as greeter in a TTY and run start-newm. Once this works, you can try.

Thanks I just wanted to try to see how it looks, but the lockscreen is beautiful

I already have greetd configured, I even add some environment variables before starting newm, I would like to add the configurations that I have to the newm documentation

[jbuchermn]

Sure, I very much appreciate improved documentation. Feel free to open a PR

[CRAG666]

Sure I will do it as soon as v2 is ready so it can be used massively
