Just to update everyone...

I waited for a USB keyboard to come in the mail. Plugged in the USB keyboard and it worked just fine. Weirdly something about running the ELRepo drivers screwed up my NetworkManager so I had to manually add nameservers in order to actually get access to any repositories.

I tried reinstalling the current kernel but I got this:

       [root@localhost ~]# yum reinstall kernel-4.18.0-147.8.1_el8_1.x86_64
      Last metadata expiration check: 0:00:10 ago on Tue 23 Jun 2020 01:31:07 PM EDT.       Installed package *kernel-4.18.0-147.8.1.el8_1.x86_64* (from BaseOS) not available.
       Error: No packages marked for reinstall.

I tried running "yum remove" and the kernel, and then running "yum install." It removed the kernel as expected but then said:

       [root@localhost ~]# yum install kernel-4.18.0-147.8.1_el8_1.x86_64
      Last metadata expiration check: 0:05:28 ago on Tue 23 Jun 2020 01:31:07 PM EDT.
       No match for argument: *kernel-4.18.0-147.8.1.el8_1.x86_64*
       Error: Unable to find a match: kernel-4.18.0-147.8.1.el8_1.x86_64

So.... no, I can't reinstall the kernel as you suggested, Phil. It looks like that kernel disappeared somehow!


This I can help with. I'm assuming you are running CentOS, not RHEL. CentOS just released their el8.2 release. You are/were running a kernel from the el8.1 release (denoted by the el8_1 release tag). When CentOS went from el8.1 --> el8.2, all the old el8.1 packages (including your kernel) were moved to the vault and are no longer available by default, hence why yum can not find the package to reinstall. To make them available again, you would need to enable the CentOS vault repo in your yum configs.

From there I thought, "What the heck? I'll update to the newest kernel and see what happens."

It updated as expected, but with the new kernel I still can't access my laptop's actual keyboard — /and/ my WiFi (Broadcom) driver stopped working. (I was actually expecting the WiFi to not work, since I was warned I'd need to repeat the process every time I upgrade a kernel).

At this point, unless someone here has any other suggestions, I'm just going to back up my data, wipe the machine and reinstall CentOS.

To sum up, as soon as I installed ELRepo's Nvidia Graphics driver:
        1) I can no longer use my laptop's keyboard after I leave the grub menu, I can only use a USB keyboard         2) It screwed up my NetworkManager so I had to manually add nameservers

....anyone have any idea why it did this???
