I have 2 GPUs: Intel HD Graphics 620 and NVIDIA GeForce 930MX Ubuntu has automatically installed the proprietary driver for the NVIDIA GPU. But, I can't see the Intel HD Graphics GPU in update manager. I think that everything on my laptop is using the NVIDIA card, wich is causing it to overheat when I don't have any applications open.

Here is the output of sudo intel_gpu_top:

intel_gpu_top

It seems like Ubuntu is not using the Intel GPU.

Is there a way to install a driver for Intel HD Graphics 620?

The Intel Graphics driver's preinstalled in the kernel.

https://www.linuxbabe.com/desktop-linux/switch-intel-nvidia-graphics-card-ubuntu shows sudo prime-select intel switches back to Intel and prime-select query shows which card is active.

  • Well, I don't see it in software & updates. The intel_gpu_top command says that there is no usage of my Intel GPU. Is it possible to switch between these GPUs? I would like to use the NVIDIA GPU for gaming and Intel for other things. – adazem009 May 12 '20 at 08:22

  • Thank you so much! I forgot that I already had this feature enabled in my previous Ubuntu installation. But, after I reinstalled it, it's gone. – adazem009 May 13 '20 at 08:23

    I have an intel processor. After upgrading from Kubuntu 18.04 to 20.04 everything seemed sluggish. With top I could see that the Xorg and kwin_x11 combined for a total processor usage between 40-50% CPU. After doing prime-select intel, both process account for ~ 1% CPU. Everything is now much more snappy and feels like it used.

    This is a very good thing to know!!!
