In my testing, the GPU does turn > off just fine. Thanks for the clarification, Xaver! You are right — I checked the power state and it does go to D3cold. The D0 state was just because nvidia-smi was waking it up. However, could we reconsider this as a feature request? My specific use case is that I want KWin to completely ignore my NVIDIA GPU. Before Plasma 6.7, setting KWIN_DRM_DEVICES was enough to keep KWin entirely away from the dGPU, which was perfect for my setup (using external tools to manage the GPU, or keeping it completely isolated for other tasks). Now, even though it sleeps, KWin still wakes the dGPU at login and attaches to it. Would it be possible to add a way to completely hide a GPU from KWin like we could before? Perhaps a new environment variable or having it fully respect the existing KWIN_DRM_DEVICES? -- You are receiving this mail because: You are watching all bug changes.
