How to Enable GPU fan settings nvidia in Linux
We found the solution. We had to run the following first and restart
Option 1
Edit the xorg.conf file:
|
1 |
/etc/X11/xorg.conf |
You should look for the NVIDIA section and add the following:
|
1 2 3 |
Option "ModeValidation" "AllowNonEdidModes" Option "TripleBuffer" "1" Option "Coolbits" "4" |
finally the file is as follows:
|
1 2 3 4 5 6 7 8 9 |
Section "Device" Identifier "Device0" Driver "nvidia" VendorName "NVIDIA Corporation" BoardName "GeForce RTX 3080" Option "ModeValidation" "AllowNonEdidModes" Option "TripleBuffer" "1" Option "Coolbits" "4" EndSection |
Note: If this file does not appear, run the following command and look for the file again
|
1 |
sudo nvidia-xconfig -a --cool-bits=28 |
After that, please change gpu fan speed in the Nvidia X server Settings windows
Tested on:
Ubuntu 20.10
- GeForce RTX 3080
- GeForce RTX 3070
- GeForce RTX 2080
- GeForce RTX 2070
- GeForce RTX 2060
- GeForce RTX 1080
Option 2
Found the solution. I had to run the following first and restart
|
1 |
sudo nvidia-xconfig -a --cool-bits=28 |
But I have another question. After reboot, The GPU control the FAN automatically. Then If I set the fan speed manually via
|
1 |
nvidia-settings -a '[gpu:0]/GPUFanControlState=1' -a '[fan:0]/GPUTargetFanSpeed=99' |
It works as it should. But when I set
|
1 |
nvidia-settings -a '[gpu:0]/GPUFanControlState=0' |
afterward, now the Nvidia X Server Settings does not update the FAN Speed although it is possible to see in Nvidia-smi that the fan speed is still changing.
By the way I updated to driver.
