That’s why I recommended booting with live media, entering a chroot environment, and removing/installing the kernels from there.
5.15 is doing the same thing. Is there a list some where of the EOL kernels?
I can confirm it’s not something going on with Plasma because gnome won’t give me the log in screen either.
To get a list of the other kernels installed, run:
mhwd-kernel --listinstalled
I have 4.19, 5.10, 5.15, and 5.4 but grub is listing these and also 5.7
hmmm, then try:
sudo update-grub
P.S.: I’m sort of out of my depth here and mostly guessing. Thus:
I still recommend removing them and installing from “scratch”, as I explained earlier.
Update-grub is still adding 5.7 to the grub menu along with 5.9
Thanks for trying to help with this.
The headers for the 419 kernel were missing. I reinstalled those. All of my kernels but one are stuck at the same screen. The other is giving me this error:
failed to start rule-based manager
If you can get to a tty please share system info … such as from here:
How to provide good information
but you can make it easier by using something like this as well:
[HowTo] use public command-line pastebin services without installing anything!
Which would mean do this and share the link:

It looks like you have the nvidia-390 driver installed with an unsupported GPU ?
NVIDIA GF108 [GeForce GT 430] vendor: Gigabyte driver: nvidia v: 390.144
It’s the same driver series I’ve always used.
And oops its 3 not a 4 
So which driver should I be using
It looks like the only drivers available are the 390xx and 470xx. I’ve always used the 390xx but according to you and from what I read it doesn’t support my card. So what am I supposed to use?
No I think the 470 doesnt support your card.
But I didnt take the time to look it up. mhwd -l will tell you whats available.
The 390xx is available which is what I’m using. Something else must be going on.
I just had a bunch of updates come in but it didn’t fix the problem. I wonder if I could change from unstable to stable?
It seems the nvidia drivers were the problem. I removed them and installed the free drivers and it’s all working now.
