( [HowTo] Resolve an unbootable Manjaro (black screen, login failed, cant boot, etc) )
Actually … I might suggest doing the regular boot … but edit the boot options to remove ‘quiet’ and replace with a ‘3’ for runlevel 3 and maybe we can see what the problem is.
Once at prompt;
To try starting the desktop (may produce useful errors)
startx
To print errors from journal since boot
journalctl -p 3 -b
To provide general system information:
inxi -v7azy
There are also ways to make quick pastes, so a way to share system info may be:
inxi -v7azy | curl -F 'file=@-' https://0x0.st
