Hi,
I am using Thinkpad P1 Gen 7 with Intel Core Ultra 7 155H and Nvidia RTX 4060.
I installed Fedora 41 workstation with KDE and updated all the packages.
I also set the dGPU to compute only and LIBVA_DRIVER_NAME=iHD.
When I monitor the iGPU power consumption using intel_gpu_top I see that it uses around 3W constantly even though the utilization is at 0% (see screenshot below).
I am using best-battery mode.
What does the slash between the watts indicate? It says 0.18 /2.92 W which has me thinking the real use is 0.18 W within a 3-watt window for the low power state.
On Windows 10 with Intel UHD 630 I fired up GPU-Z and at 350MHz (idle) it doesn’t seem to go above 0.3 W while flinging the window around. Idle it reports 0.0 W.
0.18 W with the Terminal window maximized and actively updating looks fine to me! I’m not sure the hook-up for all of GPU acceleration, Qt, Wayland, and Plasma 6, but intel_gpu_top refreshes its contents, and if that’s causing a full-Terminal re-draw, that’ll be shown with GPU load (hence the consistent GPU load with only intel_gpu_top running in Terminal regardless of nothing else on-screen). Dropping to tty might remove that as a variable.
