Title:
[mantic] Nvidia GPU not detected using on-demand
Status in gnome-shell package in Ubuntu:
New
Bug description:
Hi,
Laptop: Legion with Intel + Nvidia 3070 gpu
I reported
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2033735 but I
realize this could be a GNOME (including gdm?) issue. That's not a
hardware failure as W11+hdmi is working with on-demand. That's not
Nvidia-535 related since I get the same bug using Nouveau.
- Using Nvidia dGPU: all is ok (well, in a X11 session!)
- Using dynamic graphics:
--- Nvidia gpu is not listed in g-c-c system details (only Intel gpu is
listed)
--- App menu's option to launch with dGPU is missing
--- HDMI monitor is not detected
When I boot, I notice in gdm's screen that my monitor is not activated
(full black). It is when I use Nvidia dGPU-only mode. So that's not
only a GS stuff, as far as I can see.
I get this related to Nvidia in logs:
