PostPosted: Wed May 08, 2024 11:17 am    Post subject: Openrc and plasma [solved] Reply with quote

Hi everyone, I am actually close to finish my package manager. I can run a plasma environment with openrc now.

I am just still facing a problem with user management / rights. These are the problem I am facing:
-if I create a new user with useradd command, the user is not visible in the user list in systemsettings
-if I create a new user by the plasma systemsettings, the user will be visible, but if I change the sddm theme or the screen resolution, it's not saved (but basic configurations are saved ...)

I am running (under a virtualbox):
-Openrc 0.52.1
-Plasma Desktop 5.27.7
-Elogind 252.9.0
-Accountsservice 23.13.9

Can I have some help please to fix my issues. Because I really would like my distro running on Openrc

Let me know if you need extra information please.

So basically it was :

Code:
useradd -m -G wheel,video ism


I just saw something interesting, when I change the sddm skin, if I push the button apply plasma settings, an error occur:
Code:
The backend does not specify how to authorize

Fulgurance,

maybe I dont understand your problems ... I try to help ...

Sometimes I takes a while ... I would do a native "useradd"

Fulgurance wrote:
Code:
useradd -m -G wheel,video ism

I dont know what "ism" is ... I did in my (OpenRC) installation:
Code:
# useradd -m -g users -G wheel,audio,video,usb -s /bin/bash peter

(You must know if you want your user in wheel ... see also: https://wiki.gentoo.org/wiki/Handbook:AMD64/Installation/Finalizing#Adding_a_user_for_daily_use )

Maybe if you describe more in detail what doesnt work we could help, sorry if this does not help.

I want to provide plasma environment, so I need it work properly :wink:

So as I said (I will try to be more accurate): if I generate a new user by CLI in a terminal, with the useradd command, the new user is not visible in the plasma settings GUI.

But if I generate a new user by the plasma settings GUI, the new user is visible in that graphical user list.

Quote:

It's just a random user name I used to test the user management fonctionality, it's the name of my software.

Basically, if I login with the new account named ism, I can't see the other generated users, even generated by the ism administrator user. Do you understand ?[/code]

I will post a screenshot

Look at this screenshot, I logged with the user called ism, but the user list is empty, I can't see the user itself...

Maybe a stupid question ... but what happens if you create a user with "useradd", then do a reboot, and then check what KDE have recognized now ?

P.S.: Sorry for asking for "ism" ... I have thought there is a comma between ... and not seen there is a blank ... (sometimes I am very blind or see more than there is) :oops:

I wonder if this is relevant: https://bugs.kde.org/show_bug.cgi?id=336994 (Comments 16, 24 & 27 are Gentoo Linux users, so it also affected KDE Plasma in Gentoo Linux)

So yes, if I use the qdbus command to cache the user, it's finally visible !
So there is definitely a problem with the plasma user cache. I will check if there is a patch.

I have now another question. It's related when I try to change the sddm theme. If I try to apply to plasma settings, I have this error: "The backend does not specify how to authorize"

This is a screenshot to make you understand: https://www.zupimages.net/up/24/19/oc7s.png

By the way, if I change the resolution (as I said), the settings are not saved.

I am struggling to find the current KDE Plasma code that relates to caching users. At the time of that bug, it was a kcm module(user-manager) but there is reference to it being deleted and moved over to the plasma-desktop repo.
https://github.com/KDE/user-manager
Regardless, I have had to delete the ~/.cache from a virtual terminal while not logged in and reboot in the past to correct some issues with KDE Plasma or other applications. This should rebuild upon login.
I am assuming that the user cache for KDE Plasma is stored there. If that is the case, would be curious to know if removing or renaming ~/.cache or only the kde related files in that directory (i.e. kwin, ksplash, plasmashell, systemsettings, etc.) allows the cache to rebuild correctly after logging in.

So I tried by deleting the cache, but it change nothing

And the version I use of Plasma (5.27.7) don't user user-manager anymore

Apparently there is a similar problem in KDE Plasma 6:

Ok, then it seems like KAuth is broken on your system. This might be a local configuration issue, or it might be a distro setup issue.

@Nate Graham Thanks for helping, issue was that kauth package had missing optional building dependencies.
Now it is resolved

Hmm I will have a look. I find something interesting when I run systemsettings from the CLI as well.

Look:
https://zupimages.net/up/24/19/3f7z.png

Systemsettings complain it cannot find scaling DPU value and other similar errors

I think definitely you find the issue, because when I rebuild Kauth, I still get an error, but a different one. Something with Kauth is wrong

I rebuilt polkit-qt-1 kwindowsystem, polkit-kde-agent-1 and then sddm-kcm, and now everything work properly. It's very strange, why I had to rebuild again ?

The only bug persisting now is, the kde cache is not updated if I don't do it manually (to see all users)

Are you saying when you install kde-frameworks/kauth, you get an error? If so, what is the error?


Is DBUS running ?
Code:
echo $DBUS_SESSION_BUS_ADDRESS


What profile are you using? I am assuming you are using the correct desktop profile?
If you are not sure, what is the output of:
Code:
eselect profile list | grep '*'



The issue is not likely with your cache. That is just a symptom I think. The telling clue is when you run systemsettings from the command line it says "The backend does not specify how to authorize".
That error is directly from KAUTH source code, line 167 and line 191:
https://github.com/KDE/kauth/blob/master/src/executejob.cpp
In both instances there are comments about getting this error:
Code:
// There's something totally wrong here

and
Code:
 // This should never, never happen

This is likely a configuration issue (polkit, dbus, polkit-qt, kauth, etc), a required service not loading at boot or login, or possibly missing dependencies.

No. Sorry I realised I explained bad. No I just said when I rebuild polkit-qt-1 kwindowsystem, polkit-kde-agent-1, and then sddm-kcm and kauth, now everything work properly.

As I said at the beginning, I am doing my own distro and my own package manager, nothing with Gentoo tools.

So now the only last problem it persist is, when I create user by CLI, kde don't update the user cache. How can I fix that now ...
