I have a triple boot install on my Lenovo Ideapad 310 laptop (Windows, Ubuntu and Manjaro KDE). I have been using manjaro since 3 weeks now. But now suddenly, Manjaro doesn’t boot.
It shows a black screen with lenovo logo on it. Nothing else. No mouse pointer and no keyboard response (even the numpad light doesn’t turn on).
Ctrl+Alt+F1 to F12 doesn’t respond (The whole keyboard doesn’t respond)
Windows and Ubuntu work. I can also boot through Manjaro fallback mode.
But can’t boot through the main Manjaro installation.
You could try merging your pacnew files if you haven’t done so recently, especially this one:
PAM and PAMBASE got updated, which might prevent you from login

Due to updates from pambase 2 and pam 1 you might take care about any .pacnew files in /etc/pam.d as for example pam_tally, pam_tally2 and pam_cracklib got deprecated 1. Read in the ArchWiki 4 about managing those files.
Typical issue:
For recovery, it is enough to boot with kernel option “systemd.unit=rescue.target”, then proceed into /etc/pam.d and merge “system-auth” and “system-auth.pacnew”
