Manjaro hanging from boot

I don’t know; there are many potential possibilities for a boot failure. Normally, nobody can begin to take a guess until they have at least seen some logs, and have a good idea of your environment. Sometimes clumsy mistakes during install can be a cause; the list goes on. I will note though, that I see more issues with a Nvidia-Gnome combination, than much else.

Exactly, how old is the laptop (out of curiosity)?

Some information might help others;

inxi --admin --verbosity=8 --filter --no-host --width

and logs from after a failure to boot:

journalctl --boot=-1 --priority=3 --catalog --no-pager

As a new user, please take some time to familiarise yourself with Forum requirements; in particular, the many ways to use the forum to your benefit. To that end, some or all these links will be invaluable:

And last, but not least, the Stable Update Announcements, which you should check frequently for important update related information. Occasionally an issue might be directly related to a particular update; it’s always best to check those announcements.

I hope this helps. Cheers.
