[24.04 ISO] Set nvidia-drm.modeset=1 #333

Closed WatchMkr closed 3 months ago

WatchMkr commented 4 months ago

The image has modules_load=nvidia and nvidia-drm.modeset=0. nvidia-drm.modeset should be 1 {nvidia-drm.modeset=1)

XV-02 commented 4 months ago

Changing the nvidia-drm.modeset kernel param to 1, allows cosmic-greeter/cosmic-session to function.

However, in testing, I cannot launch native cosmic GUI applications (output of an attempt to run cosmic-term) The errors seem to be consistent for all the cosmic applications I've been trying.

Additionally, I think I'm seeing a phantom display, which is resulting in the installer presenting on a non-existent display when the live session is entered. I pulled the display list from cosmic-randr.

I can confirm successful installation of 24.04 from debug ISO 168 with nvidia-drm.modeset=1, and that there is a phantom display as shown in the cosmic-randr output. Issues with native cosmic GUI applications seem to be limited to the live session, as they work on the installed session.

This looks like driver problems. Does the iso system have the egl-wayland library installed?

XV-02 commented 4 months ago

libnvidia-egl-wayland1 is present.

Hello! I am trying to install the PopOS 24.04 Cosmic alpha 1 ISO (ISO 188 according to grub) and it seems that the issue related to cosmic-term and other cosmic applications is still present. I am unable to open cosmic-term in the live session, and the traced output when attempting to do so is the same for as the one quoted above. However, I am indeed no longer seeming a phantom display in cosmic-randr. I can also confirm via cat /sys/module/nvidia_drm/parameters/modeset that the nvidia-drm.modeset is indeed set to 1. I believe #338 is referring to the same issue.

It seems that this issue also affects running the installer itself -- during boot, the installer does pop up. However, after language selection and clicking Continue, the app closes.

Thanks for all the great work!
