Avoiding HWE Kernel (22.04)

[Felix Natter]

hello Jeffrey,

thanks for the quick reply, answers inline.

Thanks, do I need to do anything with regard to the NVIDIA
(535-)drivers?

purge right? I first installed the normal kernels, then removed the hwe
kernels (seems safer to me?).

Purging the HWE packages did not trigger initrd stuff
(this is on a vanilla Ubuntu22.04.4 VM!):

Found linux image: /boot/vmlinuz-6.5.0-28-generic
Found initrd image: /boot/initrd.img-6.5.0-28-generic
Found linux image: /boot/vmlinuz-6.5.0-18-generic
Found initrd image: /boot/initrd.img-6.5.0-18-generic
Found linux image: /boot/vmlinuz-5.15.0-105-generic
Found initrd image: /boot/initrd.img-5.15.0-105-generic

-> I guess this means that the HWE kernel was not used.
But where do these 6.5.0-*-generic kernels come from when they are not
HWE kernels? What am I missing?

If these are HWE kernels: how do I deinstall all of them (they have
higher priority in the grub menu)?

To do it the other way around (switch from stable to hwe kernel):
simply the inverse?

1. export hwe_ver=22.04
2. sudo apt install linux-headers-generic-hwe-${hwe_ver} linux-image-generic-hwe-${hwe_ver}
3. sudo apt remove linux-image-generic linux-headers-generic

Could you please explain how this helps? Will this cause old kernels to
be automatically removed (I usually like to keep them around)?

Many Thanks and Best Regards!!
