High GPU utilization at idle

I am running dual screen setup on Geforce 630. One screen runs at 1440p60hz second at 1080p60.
I have been testing these version of drivers: NVIDIA-Linux-x86_64-384.130, NVIDIA-Linux-x86_64-390.87 and NVIDIA-Linux-x86_64-410.78.

I noticed when GPU is running on idle GPU utilization with drivers NVIDIA-Linux-x86_64-390.87 and NVIDIA-Linux-x86_64-410.78 is 25%, but when using NVIDIA-Linux-x86_64-384.130 driver GPU utilization is 0%.

Is it a bug? possible fix?


See if adding

option "UseNvKmsCompositionPipeline" "false"

to the device section of your xorg.conf helps.

Nvidia GPU 970, recently started having this issue as well. Windows 7, no other issues. GPU sits at around 25% utilization no matter what I am doing, and therefore idles right around 60C, because that is the temp that the fans kick on. Will see about doing what gnerix suggested. Haven’t had this issue before, and spent the whole day checking on air flow for my rig, but it’s happening because the GPU is just 25% utilized for no apparent reason.

I only posted this here because it was the only related thing that I saw.

option “UseNvKmsCompositionPipeline” “false” worked!

I am now using 410.78 branch and everything is back to normal.
