If you have a modern Nvidia GPU (Turing [https://en.wikipedia.org/wiki/Turing_(microarchitecture)#Products_using_Turing] or later), you may also want to investigate the <code>hardware.nvidia.powerManagement.finegrained</code> option: [https://download.nvidia.com/XFree86/Linux-x86_64/460.73.01/README/dynamicpowermanagement.html]

=== Fix black screen on system with ~~Intel~~ integrated GPU ===

=== Fix black screen on system with an integrated GPU ===

If you are using non-Optimus mode on a system with an ~~Intel CPU with~~ integrated GPU, the kernel module <code>i915</code> may interfere with the NVIDIA driver. This may result in a black screen when switching to the virtual terminal, or when exiting the X session. A possible workaround is to disable the integrated GPU by blacklisting ~~<code>i915</code>~~, using the following configuration option (see also [https://discourse.nixos.org/t/nvidia-gpu-and-i915-kernel-module/21307/3]):

If you are using non-Optimus mode on a system with an integrated GPU, the kernel module <code>i915</code> for intel or <code>amdgpu</code> for AMD may interfere with the NVIDIA driver. This may result in a black screen when switching to the virtual terminal, or when exiting the X session. A possible workaround is to disable the integrated GPU by blacklisting the module, using the following configuration option (see also [https://discourse.nixos.org/t/nvidia-gpu-and-i915-kernel-module/21307/3]):

# intel

boot.kernelParams = [ "module_blacklist=i915" ];

# AMD

boot.kernelParams = [ "module_blacklist=amdgpu" ];
