Hello everyone,
As post title says, i’m facing problems while trying to activate gpu fan support on Nvidia-Prime Xorg configuration and external display. I own an Asus rog strix scar III (G531GV) which comes with an Intel iGPU and nVidia RTX 2060 dGPU. Right now iGPU is not being used at all as i only use RTX to project my laptops display on an external monitor with Nvidia-Prime. I understand that i have to add the “coolbits” option on my Xorg.conf file to enable gpu fan on nvidia-settings (Thermal Settings) panel and manually configure gpu’s fan rpms but that doesnt seem to be the case …
I used the following command to build my xorg.conf file with coolbits support:
sudo nvidia-xconfig --prime --cool-bits=28
xorg.conf contents:
# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig: version 440.44

I’ve tried different values for --cool-bits like 4, 5, 8, 12, 28 but nothing seems to be able to enable gpu fan in nvidia-settings thermal settings panel. I even tried adding cool-bits in Device section but to no avail …
Strange part is that while “Editable Performance Levels” options become available with Coolbits, gpu fan configuration does not as shown in the following screenshots:

I’ve uploaded my nvidia-bug-report.log as well in case it helps someone tracking down this issue.
My system specifics are the following:
Laptop model : Asus Rog Strix Scar III - G531GV
Installed OS : Parrot 4.9 64-bit (full updated)
Kernel : Linux parrot 5.6.0-2parrot1-amd64
Nvidia Gpu : RTX-2060 6GB
Nvidia-Drivers : Latest - Proprietary 440.82
Any help would be greatly appreciated,
Thank you all in advance!
