'''You need muxless card'''. Official solution by nvidia. | |||
==== dynamic mode ==== | |||
Like with Bumblebee, in this mode nvidia card is only turned on by need, other time it stays in power saving mode. | |||
* Pros: | |||
** better performance than Bumblebee | |||
** Vulkan, CUDA and OpenCL work, though CUDA needs an additional device creation rule https://github.com/NixOS/nixpkgs/blob/05e375d7103ac51e2da917965c37246c99f1ae4f/nixos/modules/hardware/video/nvidia.nix#L72 | |||
** pure wayland setup is supported | |||
* Cons: | |||
** there are still some rough edges noted on the top of script | |||
** launches new X11 server (and so its preferable to run WM/DE along with running program) | |||
'''1.''' Configure NixOS to allow Intel and Nvidia X.Org drivers coexist together (only needed because NixOS forces LD_LIBRARY_PATH variable propagation), and also to disable nvidia card by default. | '''1.'''

* Pros: | ==== static mode ==== | ||
** better performance | |||
** Vulkan, CUDA and OpenCL | In this mode nvidia card is turned on constantly, having impact on laptop battery and laptop health. | ||

** better performance than Bumblebee | |||
** out of box experience | |||
** works under existing X11 server | |||
* Cons: | |||
** nvidia is turned on constantly | |||
** things like Vulkan, CUDA and OpenCL are not tested | |||
** pure wayland setup is not supported | |||
