Original GitHub issue: https://github.com/ollama/ollama/issues/15721

What is the issue?

I've Ollama 0.21.0 configured to work with the GPU Intel UHD Graphics 620 through vulkan in Windows 11. In the configuration, in power & battery, only "turn my screen off" after 15 minutes is configured and the other options are using "never". Everything works fine until the screen goes off. The API accepts connections but ends in timeout. There is no GPU activity until I turn the screen on again, then API accepts connections and processes the requests.

Basically, the GPU should be available during "turn my screen off" despite of this is off to keep running just like a server.

I think WDDM power management on integrated Intel graphics can suspend the display adapter when the screen goes off, blocking Vulkan compute. This is a driver/OS-level interaction.

can this be managed by the Ollama application that is accessing the driver? is Ollama posting debug logs about this?
