https://bugzilla.kernel.org/show_bug.cgi?id=65761 --- Comment #18 from Jack <q@xxxxxxxxxxxxxx> --- >If there is a better way to find out why the fan doesn't shut off I'm pretty sure the reason the fans don't shut off is because they're reacting to the dGPU usage. In my incredibly un-scientific observation, I've noticed that the laptop gets warmer to the touch in Linux than it does in Windows. I'll be doing some actual testing on this later tonight, but it seems to me that the actual issue isn't the fans -- it's the fact that the dGPU is revving up and down on a pretty constant basis, and that's driving the fans to spin up and down with the dGPU. One thing I noticed is that if I don't have a compositor running it only goes up to power level 1, instead of two, when doing things in the OS, ie, browsing in Chrome, etc. I still don't even think it should be anything but 0 unless using DRI_PRIME, but might the compositor be interacting with the dGPU through PRIME, accidentally? I say this without having any real technical knowledge of how PRIME works. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
