Hello, I have arch installed on an external SSD and on startup, when everything is working, it boots into a terminal, where I login.
Recently, however, I have had an intermittent problem, where at this login screen I get as far as entering my username, and then it stops responding.
There are no error messages or output of any kind except a blinking cursor.
Ctrl-C, esc do nothing, and so I power my PC off and on again, after which it usually starts working again.
I am worried that at some point it will stop working altogether. How can I diagnose and resolve this problem?
Help would be very much appreciated,
Thanks

Try to preserve a log from that, don't use the power button but https://wiki.archlinux.org/title/Keyboa … el_(SysRq) or, if you can, switch the VT.
pacman -Qikk pam pambase shadow
but since it's an intermittent problem there's likely a race condition or otherwise non-deterministic behavior (RAM, CPU)

Also what's on the internal drive? Windows?
3rd link below. Mandatory.
Disable it (it's NOT the BIOS setting!) and reboot windows and linux twice for voodo reasons.

Useful shortcut! Don't know how I never encountered this before...

Which logs should I be looking at?
pacman -Qikk pam pambase shadow
What am I looking for here? When I do this I get info about the pam, pambase and shadow package files and then the following lines:
warning: shadow: /etc/default/useradd (failed to calculate SHA256 checksum)
warning: shadow: /usr/bin/groupmems (GID mismatch)
warning: shadow: /usr/bin/groupmems (Permissions mismatch)
warning: shadow: /usr/bin/groupmems (failed to calculate SHA256 checksum)
shadow: 588 total files, 2 altered files
Also what's on the internal drive? Windows?
Yes. I think I already disabled fast start, but I will double check.
Thanks for the help, I really like arch but I feel very ignorant about how it all works.

The system journal.
What am I looking for here?
File deviations, non-repo version.

so I don't really expect that to be the problem anyway.
