I am running the very latest and updated version of Manjaro and I am experiencing this issue:
I created a second user (tried both via GUI and via CLI) but every time I try to do login in KDE I have that 1) the password is not valid or 2) it remains stuck in loading the desktop.
The password is 100% valid and I also tried changing it from the main (admin) user.
Also I noticed that once I do login with the main user, when I logout I am not able to do login anymore and I need to reboot the desktop manager.
How can I troubleshoot this problem?
