Linux on the Nvidia RTX Spark Laptop: What Actually Works

Linux installs and runs on Nvidia RTX Spark laptops such as the MSI Prestige N16 Flip AI Plus, including GPU acceleration via Nvidia's open kernel driver, but a Windows-only power-management component called the Nvidia Platform Controllers and Framework has no Linux equivalent, locking the GPU to roughly 780 MHz on wall power versus about 2.2 GHz on Windows. The gap shows up starkly on GPT-OSS-120B: Windows and WSL each hit about 65 tokens per second and Nvidia's DGX Spark reached 61, while native Linux on the same laptop managed only 13.9. WSL is the practical workaround today because it rides the Windows driver stack and keeps full GPU boost on AC or battery while still running Linux-first AI tools like vLLM. The fix depends on Nvidia porting the platform controller's power-management logic into its Linux driver, which would effectively make the laptop a portable DGX Spark; until then, buyers should watch for driver updates and treat native Linux as functional but performance-crippled.
