Password not recognised - occassionally


This has happened to me on 3 separate occassions times now so I’m almost certain this is not a coincidence…

I lock my screen (sometimes directly on the laptop keyboard, sometimes on the bluetooth keyboard), I come back some time later and enter my password and it tells me it’s not recognised. I double check and press the “reveal” button to see what I’ve typed and to make sure I haven’t got caps lock on. I confirm that my password is correct so I type it again a couple more times and still no success.

I then reboot and type in the same password again at the login screen and I can login! Has anyone else experienced this?

I see a lot of these recurring in the logs - probably not relevant though

From journalctl, I see several entries

I’m very new to Manjaro (2 weeks :blush:) and KDE (but have been a CentOs, Fedora user for the last 4 years). I have provided some system info. Please let me know if there is anything else I should provide or should be looking at.


Are you by any chance using a non-US keyboard and use letters in your password?
You can try a test and change your password to be numbers only to check if it has to do with keyboard layout…

If it does not happen while you have only numbers as password, then im sure others can help you further to configure the layout to be used…

Thanks for your response. I see where you’re going with that but I’m using a US keyboard.

Hello Jade1

I’am maybe a solution for you: Open System Settings and enter devices . Check the option Activate of the keyboard. I think to help.

Thanks for your response. I tried your suggestion. I saw a notice saying “keyboard configuration not optimal - fix it” I clicked on fix it…I’ll see how that goes…
