@Bimon can you elaborate on this? Maybe share a source?

While you cannot directly boot the CDROM and upgrade with it, you CAN upgrade your packages to a limited extent with it.
The following assumes you have the 4.5GB Desktop ISO, and that you have NOT added packages beyond what was available in Chimaera's Desktop ISO.

(I am putting this here in the hopes that others who look at this may find it helpful in some way)

Run the following:

sudo apt-cdrom add

from here, you will be prompted to insert the DVD into the DVD drive, at this point you should do so. If it is NOT on a DVD, but rather a flash drive, you need to open another terminal and run the following BEFORE proceeding further with apt-cdrom:

sudo mount /dev/(your usb) /media/cdrom 

if that directory does not exist, create it with:

sudo mkdir /media/cdrom

and then mount the usb. Go back to the terminal that has apt-cdrom running, and press enter.

By this point, apt-cdrom will likely register the CDROM. From here, do:

sudo nano /etc/apt/sources.list

and ensure ALL Chimaera sources are disabled. After finishing with nano, and saving the new sources.list, run:

sudo apt update && sudo apt dist-upgrade

and look over what all will be upgraded and/or removed. If all looks good, you can press enter to proceed. From there, your system should upgrade, and once complete, a simple reboot will be sufficient to boot into your new Daedalus system.

@golinux Those images are only good up to the Raspberry Pi 4 last I looked.

To the OP, The raspberry Pi 5 *shouldn't* need any special firmware anymore to boot, its all stored on the on-board ROM now. So, potentially, the RPi4 image should/could work, though performance may not be optimal without a kernel built specially for the board.

if the xfce4 metapackage doesn't bring that in, you may want to file a bug report with Debian. IIRC Devuan doesn't modify that package from upstream.

check under /etc/modprobe.d and see if anything has blacklisted the pcspkr module

As of now the only thing that would need to be provided by a downstream distro is the kernel, as it seems. But time will tell how bad the damage will be, Trixie still hasn't even been released.

Would be amazing if you forked mint-menu (AKA MATE Advanced Menu) or brisk-menu as well, to go alongside her. She'd be unstoppable then! And it wouldn't have that awful regression where mint-menu can no longer have a custom icon.

@aluma sometimes *a* carton of cigarettes, depending on where you look. You have a good point, for sure. And of course, nothing lasts forever. I keep my i386 machines around in order to have the tooling necessary to do data recovery and other things on other i386 machines that pass by me from various people. But, there again, do I really need the latest and greatest just for that? Its not as if installs from yore aren't still on some level inter-operable with modern installs, when push comes to shove, even in  a post-sysv and post-x11 world.

I guess, deep down, its just a worry in the back of my mind that Debian will go the way of Ubuntu (snaps, etc.). I know that's highly unlikely, as it would be the ultimate identity death of Debian, but the thought still scares me.

GNOME is near-fully functional as of Daedalus, KDE has been for a while. I have used KDE with wayland on Devuan before, and at the very least on my Thinkpad T430s, it hasn't been an issue. I don't foresee your AMD GPU being an issue, but I'm not sure. Isn't ROCM also used for AI acceleration?

@WDstudios God, I miss the Aero era...didn't have the Fischer-price coloring of XP, but didn't have the sterile and soulless theme of windows 10 either. It had life! KDE can mimic this somewhat, with oxygen, but its still not even close to perfect....XFCE with Bluebird is a little bit better, IMO

well, desktop environment can make a pretty big difference. Have you checked to see if the USB mouse works at the greeter? (If its a mouse-enabled greeter like slick or sddm?) What DE are you using?
