Sure, should work. Have you rebooted?

If that doesn't solve the problem, please post the output of inxi -F

I done that on all my latest Devuan installations including Daedalus to be able to set up the graphical desktop my way. I use netinstalls and disable anything else but the standard system utilities in the sw selection, and do a reboot past the final steps including the grub install. Never had any issues, it simply worked. Independent from if I have network or not, on real HW or in a VM. The console should come up, sometimes when firmware is missing with not so nice graphics, but still readable. No Intel or NVidea involved though, pure AMD stuff.
Have you left out something, skipped an important step during expert install? What kind of PC we are talking about? efi or legacy install? What did you modify versus the procedure described here: https://www.devuan.org/os/documentation … all-devuan ?

I have something back in my mind that this problem maybe due to generating the file system with a brandnew kernel, and then trying to use it on an older distribution.

Before doing that make sure the cdrom entry is out of the way. Put a # in front of the line to uncomment it, or remove the cdrom entry completely.

Alternative on my Daedalus:

# apt list darktable
Auflistung… Fertig
darktable/stable 4.2.1-4 amd64

Anyhow, have a look at the right top of this web page. There are 5 links. Use Devuan.org and scan through the available information, it might be helpful for a beginner.

Can't imagine that POS does an installation without this essential package.

Maybe you simply need to use su - to get root access instead of simply su. The difference is the path.

When the violett URL is clicked on the link is opened, and usually correct. I don't use screenshots to save URLs.

I am not a NVidea user, but I am sure that the NVidea drivers do not require any package from the debian multimedia repo.

My suggestion: uncomment it for the time being in the sources.list and get your graphics to work.

Tried to look at my 2 dev1galaxy cookies, no luck. I need to find a tool that allows to read the contents of the cookie. Or is there a tool within FF that allows to read the contents?

Electrical cars as currently built will turn out to be a dead end.

If you can afford it install a new SSD in the workstation. I assume its a legacy installation, so switching drives should be painless.

Wrong. 6.1.0-18-amd64 and Debian 6.1.76-1 are kernel versions, the first one the Debian package numbering, second the version from kernel.org debianised. And yes, Devuan is using 1:1 Debian kernels.

You are running Devuan 5 Daedalus.  Have a look at: inxi -F or cat /etc/os-release.

@GlennW: you have to make up your mind what you want on this PC - either a legacy install (that was my initial impression) - or an (U)EFI installation. Unfortunately the prerequisites and boundary conditions slightly differ from each other. Both is possible, but you will need to take the right steps to achieve your goal.

Legacy installation on a GPT partitioned drive:
- You will need to add a 1M unformatted partition with bios_grub flag set for writing the legacy grub into that.
- Boot the install media in legacy mode. A legacy grub install to a selected device will be executed by the installer.

(U)EFI-Installation on a GPT partitioned drive:
- You will need an EFS partition (Debian and Ubuntu installers refer to the ESP by the name "EFI boot partition"), FAT32, suggested size 512M to 2048M (Win10 comes with about 110M, but this is small but not safe against update and unforeseen issues). Marked as ESP and in many cases boot flag set. 
- Boot the install media in UEFI-Mode. A EFI grub install to the ESP will be executed by the installer.
