Is there some way of getting to this package?
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
