Hi,
before I contiue to complain about some annyoances. Some things that
can't be taken for granted are good OOTB.
For example, on Arch Linux the reported scaling_max_freq is 5800000.
This isn't correct for the CPU in my machine, see
https://www.intel.com/content/www/us/en/products/docs/processors/core/13th-gen-core-desktop-brief.html
,
while 4500000 as reported by the default Xubuntu install is correct.
For the Xubuntu install I might lower the base_frequency to 3400000, but
maybe this doesn't matter at all.
root@xubu:~# hwinfo --cpu | grep Model | sort -u
Model: 6.191.5 "13th Gen Intel(R) Core(TM) i3-13100"
root@xubu:~# cat /sys/devices/system/cpu/cpu0/cpufreq/*driver

Now for a few annyoances, before I finish with good news.
The package "shim-signed" was not removed by an update that I run
manually, it was removed without a warning by the automated update.
Fortunately booting still works without it.
With grub and kernel packages hold still "friendly-recovery" auto-
generated a new, but broken grub.cfg.
Why does this happen? Neither grub nor a kernel was updated.
root@xubu:~# apt update && apt full-upgrade; apt autoremove

Fortunately I was prepared to restore it from a good grub.cfg copy.

Why do I need to tell update-initramfs to not use a swap that is
commented out by /etc/fstab?
root@xubu:~# cat /etc/initramfs-tools/conf.d/resume
root@xubu:~# grep swap /etc/fstab
# swap was on /dev/nvme0n1p4 during installation
UUID=bc0419de-6a38-4907-bb46-d2e0398228f6 none swap sw
0 0
# swap was on /dev/sda4 during installation
#UUID=671cd0ff-0428-4a17-aa63-208d41bdf5c6 none swap sw
0 0
root@xubu:~# update-initramfs -u -k all
update-initramfs: Generating /boot/initrd.img-5.4.0-42-generic
I: The initramfs will attempt to resume from /dev/sda4
I: (UUID=671cd0ff-0428-4a17-aa63-208d41bdf5c6)
I: Set the RESUME variable to override this.
root@xubu:~# cp -a /usr/src/etc_initramfs-tools_conf.d_resume

root@xubu:~# cat /etc/initramfs-tools/conf.d/resume

I hope "RESUME=UUID=bc0419de-6a38-4907-bb46-d2e0398228f6" is correct. Is
it?
I'll finish with good news.
Building the module to get Internet access worked without issues:
