If I mistype the password for Octopi it locks up the whole session. The other thing is that it is quite confusing as to what password it is asking for it shows su root and yet it really needing the sudo password for my user.
I have a different password for my admin root account as that makes more sense. I know the installer wants them both to be the same but I wouldn’t even do that in windows.
Yes, this is a known issue with kdesu, it’s not actually locked up, it’s just a long delay.
We do use exactly the same settings as upstream Manjaro for dbus, pam, etc…
I’ve spent countless hours trying to find what causes this issue with no success.
