In Debian 11 I have two 2560x1440 displays side by side in portrait mode. With the package nvidia-settings I created an xorg.conf which set these two displays to work as a single 2880x2560 display, Very nice. I would now like to do the same thing in Debian 12, but with Debian 12 I cannot find the package nvidia-settings. The page https://packages.debian.org/bookworm/nvidia-settings talks about the package but doesn't mention a repository that I can access with synaptic.

Is there some way of getting to this package?

If you have XFCE, the Display application should do it for you.
Applications -> Settings -> Display. I expect other desktops have
something comparable.

arandr will do the same, and export a script you can use as part of
your session setup.

Looks like nvidia-settings comes from "contrib". Have you enabled the contrib repository in your apt settings? Something like below:
| deb https://deb.debian.org/debian/ bookworm main contrib non-free non-free-firmware

I added "contrib non-free" to the deb and deb-src entries in /etc/apt/sources.list and ran apt update. I rebooted the machine, but before trying synaptic, I was presented with a window offering to configure and rotate the two screens. After nearly an hour of clicking, rotating, reconnecting the screens, renumbering them, I got nowhere. At one time I found myself with 180° rotation which is unusable, so I tried synaptic.

Synaptic now finds nvidia-settings, but wants 72 other packages to be loaded, including gcc which I took as a health and safety warning.

I took the risk, clicked on "apply", watched the packages load but during the installation got the message "Free nouveau kernel module conflicts with non free
nvidia module. Reboot". I saw several messages of the form:
/usr/sbin/dkms line 2497 : echo: broken pipe

which I assume I can live with. Finally the nvidia-settings installation process
stopped with
update-initramfs: Generating /boot/initrd.img-6.1.0-26-amd64

After a reboot, I found (panel)->Applications->Settings->NVIDIA X Server Settings. I learned that "right" means anticlockwise which only the newer iiyama XUB2793QSU mounting can do. The older iiyama display only turns "left", clockwise. This makes it possible to place the two fine bezels, normally on top, between the displays. The confusion of "left" and "right" was part of my problem with the built-in configurator.

The key line in /etc/X11/xorg.conf now shows:

Option "metamodes" "DP-4: nvidia-auto-select +0+0 {rotation=left},
DP-6: nvidia-auto-select +1440+0 {rotation=right}"

I now have my 2880x2560. Thanks to all those who responded. Roger

Hmm... maybe I'm wrong but this gives me the impression you were not
using nvidia's proprietary drivers, which which case you don't/didn't
need `nvidia-settings` because `xrandr` (and the various front-ends for
it) should have worked fine.

Am I missing something?

This is DKMS [1]: NVIDIA's kernel module isn't GPL compatible (but the
GPL allows you, the end user, to compile whatever you like). So DKMS
goes and compiles the kernel module in your box at package install for
you. That's what gcc is for.

Somewhere between magic and alien tech, if you ask me :-D

Instead of using nvidia-settings, you could also create a /etc/X11/xorg.conf and edit the settings you need.

Yes, xorg.conf ois no more needed, as the driver itself checks the settings, but in some cases xorg.conf might help.

I allow myself to attache mine here from the old days, it is for nvidia and it might be helpfull. It is small, so it does not stress the servers too much.

This is a multi-part message in MIME format.

Sorry, just dicovered, it is not the full xorg.conf.

This is the correct one, and below you can see, where the resolution can be forced.

Using xorg.conf is nice, when you need special settings.

Hope this helps (and sorry again, to attach a file, but I suppose, this makes it for the op easier).
