Symptoms: When I run startx, the fan slowly accelerates to max. When I exit back to console, the fan slowly decelerates back to normal.
Things that may be relevant: using no session manager or display manager. I am using Compiz + Emerald + xdesktop, Linux-ck-haswell + nvidia-ck-haswell. I’m on an I7 5820k + ASRock x99 board using EFIStub to boot.
In nvdock under Thermal Settings, it shows my GPU temp at 27-29°C and 0 rpm for Fan0 speed. nvidia-smi shows fan speed at 33%. I enabled fan speed control for nvidia-settings but changing the value has no effect. If I set fan speed in nvidia-settings, nvidia-smi reflects the change but actual fan speed does not change. I tried reverting to stock kernel and driver from official repo but problem persists. Using nouveau driver does not exibit this problem.
