Hanging PC on boot

Hi all.

My PC hangs sometimes on booting on this moment:

I can't switch to tty.

Please, explain what you mean with sometimes. Maybe on reboot? After upgrading system? Long time shutdown? whatever...

Not a good idea to edit first post, without comment.

So your inxi is, (read again the wiki page for format)

After reboot or shutdown. Randomly. Today it was two times after reboot, but I did reboot 5 - 10 times.

We can't do much in such random cases.

Some standard advice:

  • Make sure packages are updated.
  • Use fallback options of your kernel.
  • Boot a different kernel. If you have only one, it's time to add at least one more.
  • Check for kernel errors in journal, for the failed boot
  • If nothing helps, remove plymouth, with caution on every requirement, reading Archwiki. Don't forget to change sddm plymouth to standard.

Thanks. Will try.

Yes, seems like it works well with kernel 5.4.84-1-lts (thanks for help).

But how to know why it doesn't work with 5.10?

Check the source code :wink:

It's complicated and in your case it is related to Nvidia GPU.
This will be solved as soon as arch linux kernel get to 5.10.
