Hi guys,
I've been able to successfully get a Devuan Daedalus GNOME setup up and running and I wanted to share with you a couple of tips and bug workarounds.

1) First of all, the RefractaInstaller will luks-encrypt - if chosen to do so - the disk partitions with LUKS2 and the argon2id PBKDF key format but this is incompatible with GRUB and the system will never boot.
To solve this, you have to convert the PBKDF key format from argon2id to argon2i at least:

sudo cryptsetup luksConvertKey /dev/whatever --pbkdf argon2i

sudo update-initramfs -u -k all

sudo update-grub

You can also convert it to LUKS1 but it might be a hit or miss:

sudo cryptsetup convert /dev/whatever --type luks1

2) pipewire, pipewire-pulse and wireplumber will not autostart after login, so I created three .desktop files with menulibre, containing each the required command to start them:

/usr/bin/pipewire
/usr/bin/pipewire-pulse
/usr/bin/wireplumber

Then you need to move them from ~/.local/share/applications to /etc/xdg/autostart or ~/.config/autostart (create it if missing).
Another simpler way would be to run gnome-session-properties but I couldn't find it anywhere in the repos.

I'd recommend you to install pipewire-libcamera as well.

3) software-properties-gtk does not start, it crashes due to a python error about an undefined variable (something like eol_date and distro.eol).
I commented out some lines in the .py script and got it somewhat working but it seems a suboptimal experience and it needs a proper fix.

4) Maybe related to 3): GNOME Software gets populated by flatpaks only and lacks .deb packages.

5) The backlight brightness gets maxed out on every boot and to fix this we have to add a line in the /etc/rc.local script above exit 0 like this:

echo [value] | tee  /sys/class/backlight/amdgpu_bl0/brightness (in my case).

To completely install the GNOME desktop I'd advise you to use the tasksel command that also allows you to delete the default XFCE environment if you don't need it.
In this case, moreover I would run:

sudo apt purge xfce4*
sudo apt autoremove

With that said, Devuan with GNOME rocks! It feels snappier and even stabler than Debian Bookworm itself.
