while playing around with face/fingerprint unlock for my laptop, I messed up pam (Linux Pluggable Authentication Modules) and no passwords were working anymore except for the root account. At first I was still on my account, but then I stupidly rebooted and could only log in as root. After so many config edits, I gave up and instead booted up windows (my laptop’s dual booted), setting up a new linux install in VirtualBox, and then copying over the PAM config files from the vm to the actual Linux install.
and it all somehow worked!
I am now facing another issue which I’m gonna say here in the hope somebody has already ran into it: after updating to KDE plasma 6, tap to click works on my touchpad, but actually, physically, pressing on the trackpad doesn’t work. I can hear the pad’s physical clicking noise, but nothing happens os wise
