Password issue with KDE-Plasma

I would prefer, after understanding what was wrong, to have sort of Debian root privileges : one password for root and one for my session.

I am pretty sure it just amounts to giving root a password. In a terminal:
$ sudo passwd root

You may want to read https://help.ubuntu.com/community/RootSudo before.

I wonder if it is related to this bug that is now fixed upstream. It was working for me just before I installed doas and now it does not. I could run as a normal user a password screen would pop up and I would enter my admin password and it worked. Not sure what changed.

Found this link in the /etc/sudoers.d/kdesu-sudoers file.

Step 1

sudo passwd (as a method)

password validated su command in terminal

unvalidated root password in graphical software (same with login passwd)

Step 2

sudo passwd root (as a method) with the very same password as in step 1

password validated su command in terminal

unvalidated root password in graphical software (same with login passwd)

Can KDE Walled have anything to do with this issue ? Indeed...

KDE Wallet Manager is a tool to manage passwords on the KDE Plasma system. By using the KWallet subsystem it not only allows you to keep your own secrets but also to access and manage the passwords of every application that integrates with KWallet.

see https://wiki.archlinux.org/title/KDE_Wallet

Disable KWallet

[Wallet]
Enabled=false

My kwalletrc file contains :

[Wallet]
First Use=false

[EDIT]

More intresting : after a while I had the automatic lock screen but I couldn't unlock with my user's password. Weird !

Hi,

As Triskel is running under KDE environnement (it's unfortunately not precised IT IS Plasma on the downloads page), I've just installed it in a virtual machine to have a try and everything is just AWSOME ! No password issue, and what a beautiful desktop Triskel is !

Back to this issue, you probably guessed I've installed kde-plasma-desktop on a machine where the Trisquel iso was installed.
My desktop display manager remained LightDM, but as Triskel uses the 5.24.7 Kde plasma environement, SDDM display manager is used instead of LightDM. Indeed ...

The Simple Desktop Display Manager (SDDM) is a display manager. It is the recommended display manager for the KDE Plasma and LXQt desktop environments. https://wiki.archlinux.org/title/SDDM

With an apt install kde-plasma-desktop, SDDM will be installed.

So System Settings/Login Screen should fix the problem and maybe explains why I couldn't unlock my screen.

Choosing a desktop environement is very important when you are on Linux.

I used Mate for a long time and is is great, but I wanted more features. But Gnome environement is just a love killer for me : customisation is too complicated, so many extensions aren't working, no desktop, annoying activity button...
KDE offers me a lot of very nice softwares I often use and allow good gadjets like KDEconnect with my smartphone in its environnement.
I won't discuss the choice of users.

The Tasksel command is a good way to install a metapackage like a desktop environnement in Debian but when I tried it with Trisquel I just found Gnome metapackage.

I really missed some usefull information on the download page before installing Aramo.
Maybe a thumbnail or a link to a video could be fine in the future to present every iso ???

Hi

Sorry guys but I think there can be a bug with KDE Plasma and Trisquel.

As my Triskel try succed in a virtual machine and the issue was too complicated for me, I decided to install Triskel in my machine, but...

Baaaam ! Same issue !
This is very frustrating when you have to upgrade Trisquel after an installation and have to do it with the terminal.
I've reinstalled Triskel two times, the iso is SHA256 and GPG checked, the solutions proposed above don't work even on a fresh install. This is always the same issue.
