Dear Maintainer,
*** Reporter, please consider answering these questions, where
appropriate ***
* What led up to the situation?
I have installed Debian 11 (debian installer RC3) on a PC having a
Nvidia GeForce 8500 GT as main graphics card.
The graphicall install process went well. After finishing the
installation and reboot, I got a blank screen and "Input not supported"
on my monitor.
I changed to tty2 and logged in, and saved the dmesg output (attached),
I noticed that "nouveau" driver was loaded but there was no info about
my card not supported or needing additional firmware.
* What exactly did you do (or not do) that was effective (or
ineffective)?
I have rebooted and edited the "linux" line during Grub menu, to add
"nomodeset" and then I could have a fallback graphics mode.
I have installed the isenkram-cli package and ran
isenkram-autoinstall-firmware as suggested in the release notes and it
installed firmware for my realtek card (unrelated) and
firmware-misc-nonfree, but rebooting makes Linux pick the nouveau driver
again.
I have installed manually the nvidia-detect package and then I learned
that this card needs the nvidia-legacy-340xx package, which is not
present in bullseye.
I tried to install manually the nvidia-legacy-340xx-driver package from
sid and got the system showing a graphical environment without the need
of adding "nomodeset" to the grub linux line.
However later I read https://wiki.debian.org/NvidiaGraphicsDrivers and
found:
"Version 340.108 (legacy GPUs) (supported devices)
Older legacy driver, for GeForce 8 series through GeForce 300
series. No Vulkan support, supports up to OpenGL 3.3 depending on your
card.
Use of the 340-series driver is strongly discouraged. It is not
included in stable releases of Debian anymore, has serious unfixable
security vulnerabilities, and may not be updated for new kernels in a
timely manner. You are highly recommended to use the built-in Nouveau
driver if security is a priority. "
So I uninstalled the package.
* What was the outcome of this action?
I'm not sure which is the best way to get this system working, but
anyway I think the average user would get puzzled about dmesg not
alerting anything wrong but the system not showing graphics unless
"nomodeset".
* What outcome did you expect instead?
I think that dmesg should alert the user that the card is not well
supported by nouveau and/or would need to install additional firmware or
be used in fallback mode.
Kind regards,

The missing firmware should have been fixed in installer RC3 *if* you
use an installer image that includes firmware, but not if you use the
default images. Which did you use?
On the kernel side we should try to fix the blank screen with an
earlier check for firmware in nouveau, similarly to the way we patch
the amdgpu and radeon drivers. (Although those patches now seem not to
be completely effective.)

Well that's expected. The kernel driver and firmware are two different
things that work together. Installing the firmware should allow
nouveau to work properly.
Are you saying that even with firmware-misc-nonfree installed, you
still get a black screen when you don't use "nomodeset"?

I used the official image without firmware but was expecting that using isenkram-autoinstall-firmware afterwards was equivalent.

Exactly.
At the end of August or beginning of September I can do an install using the image with firmware but I'll suspect that the results will be the same, because the needed firmware is not in Debian non-free either (card not supported in Bullseye). I think that nouveau should somehow output that message (card not supported) so the user gets a hint about what's happening.
Kind regards
