Package: gdm3
Version: 43.0-3
Control: affects -1 xorg
In the journal I discovered the following errors (EE) that had been
issued during boot:
/usr/libexec/gdm-x-session[992]: (EE) modeset(0): Failed to set CTM
property: -13
/usr/libexec/gdm-x-session[992]: (EE) modeset(0): failed to set mode: No
such file or directory
The parts “(EE) modeset(0): Failed to set CTM property: -13” and “(EE)
modeset(0): failed to set mode: No such file or directory” are shown in
yellow. Here's what immediately preceded the error:

…
A higher-level error (which might be related or not) is that X.Org
starts instead of Wayland (whereas before the upgrade from Debian 11/12
to Debian 12, Wayland started).
I tried to get more information on the first of the two error messages:
# apropos gdm-x-session
gdm-x-session: nichts passendes.
# man gdm-x-session
Kein Handbucheintrag für gdm-x-session vorhanden
# apropos CTM
CTM: nichts passendes.
# apropos modeset
modesetting (4) - video driver for framebuffer device
# man modesetting
The last call succeeds, but the man page contains no information on CTM.
However, I'd expect to get at least some idea on what is going on (at
least on what CTM means and what is property “-13”) from locally
installed documentation.
As for the second error, it would at least help to understand which file
or directory is searched for.
As for repairing what goes wrong under the hood (if anything), here are
some details for maintainers and developers:
The machine runs Debian 12 “bookworm”. The motherboard is ASUS WS C422
PRO/SE with a built-in graphic chip ASPEED AST2500 64MB (to which
nothing is connected) and an inserted PCIe graphics card NVIDIA®
GeForce® GTX1660 Ti 6GB (to which a 2560×1440 monitor is connected via
DisplayPort).
Gratefully,
AlMa0
