Hi there,

I have two HP Z30i connected to Nvidia GeForce GTX 670. After last
upgrade I'm able to use only one monitor.

When running linux-image-6.7.9:

File a bug against the kernel: reboot to the 6.7 kernel if it is not
currently running, install the reportbug package if it is not installed already, then run

$ reportbug linux-image-$(uname -r)

Good luck,
Sven

A year later, different setup but same problems persist. I just
installed Sid on machine equipped with GeForce GTX 750. When running
Bookworm kernel 6.1.0-31-amd64 all monitor work as expected. After
switching to Sid kernel 6.12.16-amd64 HDMI-2 status is disconnected and
one of the monitors is blank.

Any suggestions?

I have a GK107 with a different but likely related problem, and with identical timing: upgrade from 6.6.x to 6.7.x: https://gitlab.freedesktop.org/drm/nouveau/-/issues/385

I've seen recently other bugs with old NVidias, plus another I filed: https://gitlab.freedesktop.org/drm/nouveau/-/issues/214

These are making me suspect support for these oldies is disintegrating as kernel
versions increment. When booted to a failing kernel, do you see any of the same drm and/or DDC errors in dmesg that you can see in the #385 bug? It might be worth
trying my workaround of 2025-03-08 comment in #385.
