5.15.0-113-generic and 6.5.0-41-generic kernels with NVIDIA card lost video

[Jeffrey Walton]

Hi Everyone,

I've got a Dell XPS 8930 with a GeForce GTX 1060 from NVIDIA. It has
been running ubuntu for about 5 or 6 years with very few problems. I
keep two kernels on it -- linux-image-generic and
linux-image-generic-hwe-22.04. If things go sideways on one kernel,
then I can switch to the other kernel.

After recent kernel updates, I lost video. The machine is dead when
sitting at the keyboard. I see two or three boot messages and then
screen output freezes. I cannot switch to a virtual terminal. However,
I can SSH into the machine.

The problem affects both kernels 5.15.0-113-generic
(linux-image-generic) and 6.5.0-41-generic
(linux-image-generic-hwe-22.04). The machine first started exhibiting
symptoms when using 6.5.0-41-generic (6.5.0-39-generic was Ok). I
switched to 5.15.0-112-generic and it was Ok. Then an upgrade brought
in 5.15.0-113-generic and it broke, too.

I'm not sure what to do at this point since I have never experienced a
time when both kernels were broken. I like using linux-image-generic
and linux-image-generic-hwe-22.04 because I get the automatic updates.
I'm not sure I want to start blacklisting kernels through apt-cache
policies, and trying to reinstall and pin old kernels.

This is a pretty crappy question, but what are the options here?
