Using passwords from kwallet in i3

Question

I recently installed the i3 window manager on my kubuntu system.

When I log in to i3, network manager will not automatically connect to wifi, as it doesn't have access to the passwords.

I can run kwalletmanager and open the settings window. Here I can open the wallet. But when I try to run kwalletd I get the following error:

QDBusConnection: session D-Bus connection created before QCoreApplication. Application may misbehave.
kwalletd(6836): Communication problem with  "kwalletd" , it probably crashed. 
Error message was:  "org.freedesktop.DBus.Error.UnknownInterface" : " "No such interface 'org.kde.KUniqueApplication' at object path '/MainApplication'" " 

I haven't been able to find information about how to start kwalletd outside the kde desktop, or find much information about how the the desktop does versus the system.

Thanks

Answer 1

I have found a way to get round my problem:

In the wifi settings, wifi security I can choose to make to Store password for all users (not encrypted) which then lets me access the connection from i3, although I still have to activate the connection.

It works but it's not quite optimal for me, so I'm still open to other ideas :)

Answer 2

Assuming that you've already set up sddm for opening your kwallet, I propose such option:

1. Install libpam-kwallet-common (KWallet integration with PAM)
2. Add this to your i3 config

    exec --no-startup-id /usr/share/libpam-kwallet-common/pam_kwallet_init

The path can vary between distros.On Gentoo it's /lib64/libexec/pam_kwallet_init.
That will automatically launch kwallet and try to open it with the same password you use to log in.
