Ubuntu 24.10 under Wayland, and Nvidia

I was led to believe that the prior problems of running a Nvidia card were fixed under Wayland in Ubuntu 24.10.

So I upgraded from 24.04 to 24.10 and ran under Xorg, solved some various upgrade issues, and it seemed to run fine.

Then I enabled Wayland. With some minor problems, it ran fine. I decided to put the Nvidia into "Performance mode", and it seemed fine until I checked nvidia-smi and noted that only gnome-shell was being accelerated.

Here I show via the cli that the Nvidia Performance Mode is selected...

Here is show the GUI showing Performance Mode under Xorg... enter image description here

Here is nvidia-smi running under Xorg... note the full compliment of processes that are accelerated... whereas under Wayland it only shows gnome-shell...

So my question is... is this a Wayland or Nvidia problem? What steps might I take to further troubleshoot this and fix it?

Update: So I upgraded from 24.04 to 24.10 and ran under Xorg, solved some various upgrade issues, and it seemed to run fine.

I find that I can't open folders on my Desktop, in Xorg, in "Performance Mode". "On-Demand" works fine.

    Short answer... the NVIDIA drivers are a mess.

    Three workarounds... pick one...

    1. run NVIDIA in On-Demand mode in Xorg

    2. install Nemo and switch prefs in the "Desktop Icons NG" (DING) extension to use Nemo in Xorg

    3. use Wayland with NVIDIA in Performance Mode.

  2. Nivida GPU, with 560.35.03 on performance mode. Worked fine on Xorg but did not work at all on Wayland. Adding the parameter DRI_PRIME=1 to /etc/enviroment and rebooting did the job for me!
