the last update to 22.1.0 ruined my plasma mobile install. So I build a new image with buildiso and installed the 22.1.0 plasma mobile version. Everything works, but I have this strange behavour: when I login, kded5 asks my password again to enable the wifi, although I used the same password as my login password for the wallet. Before, it never asked to create a wallet to enable wifi, maybe it’s a new feature.
I already installed kdewallet, but nothing seems wrong there. I also tried to disable the wallet, but then the wifi always asks the wifi password.
It seems like sddm and kwallet are not working together.
As I understand it, Plasma Mobile actually does an autologin and then locks the screen, so when you are “logging in”, you are actually just doing a screen unlock. Hence, you never enter your password into the display manager, and hence, PAM integration for KWallet, gnome-keyring, etc. cannot work.
What you can do is to open kcmshell5 networkmanagement (the desktop version of the network management configuration, which has more settings available), edit your connection, go to “Wi-Fi Security”, and pick “Store password for all users (unencrypted)”.
