Black screen on Nvidia Linux due to WGPU GPU selection

For some reason, `wgpu` seems to think I have an IGPU (on a `9950x3d`) and attempts to render with it, leading to a black screen. I was able to override the GPU selection with `WGPU_POWER_PREF='high'`, forcing it to prefer my discrete GPU ([related issue](https://github.com/iced-rs/iced/issues/2810)). Would it make sense to make this a default in the nixos module?  <details> <summary>Logs</summary> <pre><code>thread '<unnamed>' panicked at /nix/store/eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee-vendor-cargo-deps/c19b7c6f923b580ac259164a89f2577984ad5ab09ee9d583b888f934adbbe8d0/sqlite-0.36.1/src/cursor.rs:159:31: called `Result::unwrap()` on an `Err` value: Error { code: None, message: Some("failed to convert") } note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace 2025-04-25T20:37:12.721Z INFO [wgpu_hal::vulkan::instance] Debug utils not enabled: debug_utils_user_data not passed to Instance::from_raw 2025-04-25T20:37:12.729Z INFO [wgpu_hal::gles::egl] Using Wayland platform 2025-04-25T20:37:12.730Z WARN [wgpu_hal::gles::egl] No config found! 2025-04-25T20:37:12.730Z WARN [wgpu_hal::gles::egl] EGL says it can present to the window but not natively 2025-04-25T20:37:12.737Z INFO [iced_wgpu::window::compositor] Settings { present_mode: AutoVsync, backends: Backends( VULKAN | GL | METAL | DX12 | BROWSER_WEBGPU, ), default_font: Font { family: Name( "FiraCode Nerd Font", ), weight: Normal, stretch: Normal, style: Normal, }, default_text_size: Pixels( 14.0, ), antialiasing: None, } 2025-04-25T20:37:12.742Z INFO [wgpu_core::instance] Adapter Vulkan AdapterInfo { name: "NVIDIA GeForce RTX 3090", vendor: 4318, device: 8708, device_type: DiscreteGpu, driver: "NVIDIA", driver_info: "570.133.07", backend: Vulkan } 2025-04-25T20:37:12.742Z INFO [wgpu_core::instance] Adapter Vulkan AdapterInfo { name: "AMD Radeon Graphics (RADV RAPHAEL_MENDOCINO)", vendor: 4098, device: 5056, device_type: IntegratedGpu, driver: "radv", driver_info: "Mesa 25.0.3", backend: Vulkan } 2025-04-25T20:37:12.742Z INFO [wgpu_core::instance] Adapter Vulkan AdapterInfo { name: "llvmpipe (LLVM 19.1.7, 256 bits)", vendor: 65541, device: 0, device_type: Cpu, driver: "llvmpipe", driver_info: "Mesa 25.0.3 (LLVM 19.1.7)", backend: Vulkan } 2025-04-25T20:37:12.779Z INFO [wgpu_core::instance] Adapter Gl AdapterInfo { name: "NVIDIA GeForce RTX 3090/PCIe/SSE2", vendor: 4318, device: 0, device_type: Other, driver: "", driver_info: "", backend: Gl } 2025-04-25T20:37:12.779Z INFO [iced_wgpu::window::compositor] Available adapters: [ AdapterInfo { name: "NVIDIA GeForce RTX 3090", vendor: 4318, device: 8708, device_type: DiscreteGpu, driver: "NVIDIA", driver_info: "570.133.07", backend: Vulkan, }, AdapterInfo { name: "AMD Radeon Graphics (RADV RAPHAEL_MENDOCINO)", vendor: 4098, device: 5056, device_type: IntegratedGpu, driver: "radv", driver_info: "Mesa 25.0.3", backend: Vulkan, }, AdapterInfo { name: "llvmpipe (LLVM 19.1.7, 256 bits)", vendor: 65541, device: 0, device_type: Cpu, driver: "llvmpipe", driver_info: "Mesa 25.0.3 (LLVM 19.1.7)", backend: Vulkan, }, AdapterInfo { name: "NVIDIA GeForce RTX 3090/PCIe/SSE2", vendor: 4318, device: 0, device_type: Other, driver: "", driver_info: "", backend: Gl, }, ] 2025-04-25T20:37:12.782Z INFO [wgpu_core::instance] Adapter Vulkan AdapterInfo { name: "AMD Radeon Graphics (RADV RAPHAEL_MENDOCINO)", vendor: 4098, device: 5056, device_type: IntegratedGpu, driver: "radv", driver_info: "Mesa 25.0.3", backend: Vulkan } 2025-04-25T20:37:12.782Z INFO [iced_wgpu::window::compositor] Selected: AdapterInfo { name: "AMD Radeon Graphics (RADV RAPHAEL_MENDOCINO)", vendor: 4098, device: 5056, device_type: IntegratedGpu, driver: "radv", driver_info: "Mesa 25.0.3", backend: Vulkan, } 2025-04-25T20:37:12.782Z INFO [iced_wgpu::window::compositor] Available formats: Copied { it: Iter( [ Rgba8UnormSrgb, Bgra8UnormSrgb, Rgba8Unorm, Bgra8Unorm, ], ), } 2025-04-25T20:37:12.782Z INFO [iced_wgpu::window::compositor] Available alpha modes: [ Opaque, PreMultiplied, ] 2025-04-25T20:37:12.782Z INFO [iced_wgpu::window::compositor] Selected format: Rgba8UnormSrgb with alpha mode: PreMultiplied</code></pre> </details>
