Thanks Phil—
To clarify, it's not a USB keyboard. I have CentOS 8 installed on a
mid-2009 MacBook Pro.
I was never able to install using the Nvidia .run installer from their
website. It always gave me the "Unable to find the kernel source tree for
the currently running kernel" error — even though I made absolutely sure
that kernel-headers and kernel-devel 100% match my kernel.
You asked "Do you think it is related to the way we regenerate the
initramfs image?" And the answer is I have no idea! I've only been using
Linux for two months, and that was on a VPS I'm running. I've only had it
running on a physical machine for a couple weeks. I'm still trying to
figure out what initramfs is.
But I've got another issue now; the machine got hung during booting so I
powered it off with the power button. Now if I try to boot into recovery
from the ISO the screen goes black with a solid (not-blinking) cursor in
the upper left of the screen and just completely freezes. If I try to boot
from grub like normal (with a non-functioning keyboard) it freezes after
about a page of boot messages and becomes 100% unresponsive with a solid
(not-blinking) cursor.
So for right now I can't access the machine at all, I couldn't even
reinstall CentOS if I wanted to. Let me get through this challenge, if I
haven't completely fried the hardware, and I'll come back to you once I'm
ready to troubleshoot the ELRepo-related issue.
