There is no option.

Perhaps because

  • my PC is a desktop
  • I use the intel iGPU for the monitor and the NVIDIA dGPU for computing.

Please open a seperate thread as this topic is about a laptop with Optimus technology. Your desktop setup is something completely differemt…

@promeneur No, I’m on a couple of desktops running Tumbleweed, the one above and my main system with dual Nvidia which is T400 for displays and Tesla P4 for compute;

@promeneur Are you on GNOME, it’s only integrated there…

I am on KDE.

@promeneur ahh, then switchrooctl from the command line only… which I assume works? I beleive the Plasma folks are working on the interface, but I suspect you will need to check upstream.
