#StackBounty: #nvidia #multiple-monitors #power-management NVIDIA Adaptive power management not working with 3 monitors?

Bounty: 50

I have 3 monnitors 1920 – 3860 – 1920 and when all 3 are connected NVIDIAs adaptive powermanagement is suddenly not working anymore. It always is at max even when idling on desktop.

As soon as I disconnect any of the 3 monitors he starts to gear down again and the fan even totally stops.

Is there a way to make it work with 3 monitors?

System info:

  • Kubuntu 17.10 with backports
  • NVIDIA Driver 396.18 from repository
  • GeForce GTX 970

Update: I am now on Kubuntu 18.04 and have the NVIDIA driver 390.48 But still the same problem.

#StackBounty: #drivers #nvidia #graphics #xorg What configuration files in Ubuntu control the graphics drivers in a dual GPU system?

Bounty: 50

I’m trying to get an NVIDIA 970M GPU working after something went wrong with the drivers. I’ve tried purging and manually wiping the system of everything nvidia/cuda related and reinstalled both from the ppa:graphics-drivers/ppa and from the NVIDIA installer.

Both approaches fail to get the system to use the NVIDIA GPU (as evidenced by nvidia-prime which I use to switch to the NVIDIA GPU, but after reboot it always returns to the onboard intel GPU).

  • What I’m trying to understand now is exactly what configuration in
    ubuntu is used to configure which graphics drivers are actually
    loaded?

  • How do I actually query the kernel to understand what drivers it
    thinks are available, and which drivers it is using?

  • Are there logs other than dmesg (with show nothing special) that I
    should be looking at to debug this?

Bounty: 50

I have installed Nvidia (Geforce 940MX) Graphics driver version 384.111 from Softwares & Updates > Additional Drivers.

When I open “Nvidia X Server settings” it shows empty.
I have tried

sudo apt-get purge nvidia*

and reinstall drive manually still facing the same issue.
I have tried to switch drivers and reboot the computer.

also, I switched to “Ubuntu xOrg” and reinstall the driver but no luck showing the same result like below image.
