=== Fix black screen on system with Intel 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. To solve this, you can try blacklisting <code>i915</code> by adding the following to your Nix configuration (see also [https://discourse.nixos.org/t/nvidia-gpu-and-i915-kernel-module/21307/3]): | |||
<syntaxHighlight lang="nix"> | |||
boot.kernelParams = [ "module_blacklist=i915" ]; | |||
