Bug#1074481: gdm3: There is no option to log in with Wayland when an Nvidia eGPU is connected

Package: gdm3
Version: 46.0-2+b3
Severity: normal

Dear Maintainer,


I don't know if this is the correct way to report a bug; I am new to this. I will explain the problem: after installing the proprietary Nvidia drivers and connecting a graphics card, the option to log in with Wayland does not exist. This happens both in Sid and Debian 12.

My hardware is as follows:
-My laptop is a Framework Laptop 13 with a 7840U processor
-My graphics card is a 1080ti
-My dock for the graphics card is a TH3P4G3

After installing the NVIDIA drivers through the command "sudo apt install linux-headers-amd64 nvidia-driver firmware-misc-nonfree nvidia-cuda-dev nvidia-cuda-toolkit" and then signing them following the tutorial: https://wiki.debian.org/SecureBoot#Using_your_key_to_sign_modules, I followed the Wayland section of the following tutorial: https://wiki.debian.org/NvidiaGraphicsDrivers#Wayland.

After this, the drivers do not load at system startup. I suspect it is because the GPU is not detected (it says so at startup) for some reason that I do not understand. Once the system starts, after logging in, I simply load the drivers manually with the command sudo modprobe nvidia_drm. After this, the screens connected to it turn on without any problem and the graphics card is operational.

But the performance is poor; I suspect this is because the main graphics card is still the integrated one in the laptop. To fix this, I simply restart the display server with the command sudo systemctl restart gdm3. This works perfectly and the performance becomes good, except that I only have the option to use X11.

I understand that this is an error and it is a supported function. I am subscribed to the debian-bugs-dist mailing list, so I will keep an eye on the process. For any need of logs or anything else, I am fully available.

Thank you very much in advance for reading this.
Best regards.
