While installing Ubuntu 20.04 on a new computer, I encountered a No irq handler error. After booting from an USB drive and selecting install Ubuntu, the no irq handler message showed up a few times followed by screen artifacts.

    Does this answer your question? My computer boots to a black screen, what options do I have to fix it? – Pilot6 Jul 11 at 18:49
  • @Pilot6 I'd prefer to keep this question open if this is OK with you because the OP's solution seems to be specific for fixing the No irq handler for vector boot message especially when it is accompanied by visual artifacts as it is in the screen photo in the question. – karel Jul 12 at 0:05

After further research, I found a reddit user with the same problem as me. The solution is to boot Ubuntu under safe graphics mode. The error would still occur but it will boot into Ubuntu after a while.
