Big sorry guys, but that was quite a big hack and maintaince burden with a bunch of rough edges. Better to wait for proper solution from Nvidia.

Does it make sense to test this with wayland?

I'm using way-cooler on a thinkpad p70 with an nvidia quadro m3000m gm204.

I'll hopefully get around to trying this out this weekend.

It would be nice to have it documented in the manual as well, perhaps under the section on nvidia graphics.

error: 
Failed assertions:
- Sessions (name: nvidia-optimus, session: none+i3), (name: display-manager, session: none+i3) are not in 
(use ‘--show-trace’ to show detailed location information)

I've tried several things, uncommenting session = "none+i3";, driver = [ "nvidia" ]; and services.xserver.displayManager.xdm.session = "none+i3"; but I keep getting the above error.

I'm sorry to say I don't really understand what it tries to tell me, or how to solve.

I do use Xwayland (for firefox and xterm (to be replaced with alacritty)) and would very much like to test your work on this setup. I do not have services.xserver.enable = false; (which defaults to true).

Can you give me a hint on how to proceed?

Doh you are right, I've included services.xserver.enable = true; and services.xserver.autorun = false; now.

And session = "none+i3"; + services.xserver.windowManager.i3.enable = true;.

There is no way to test Xwayland without the last two?
