It sounds like you're referring to:

So this would be a kernel bug. However in my experience such kernel
errors are also not fatal and won't cause permanent graphics problems.
Looking at your CPU model however:
Core(TM)2 Duo CPU E8500
I can tell you are experiencing bug 1727356, which is not related to kernel
errors at all.

Title:
FIFO underrun error
Status in xorg package in Ubuntu:
New
Bug description:
Subunit 18.04 LTS
System will not boot.
I updated graphics drivers I think erroneously, then received the
underrun errors and created a swap partition by accident following a
fix for a similar error as was having trouble booting crypt. I
commented out the swap and turned off swap and have updated my drivers
and purged previous. I can access terminal, yet still cannot boot due
to the undercut. I think I need to create a .conf file for the
graphics drivers.
