I'm sorry for spamming this bug report, I should've make all my tests before posting anything.
I made a clean install today but, this time, without installing the proprietary drivers during setup. I installed the Nvidia driver after the first batch of updates, via the Additional Drivers application. And I can't reproduce this issue anymore. It's working as it should. It unfortunately means that installing the proprietary drivers during setup isn't working well. For instance, I had to manually install the nvidia-dkms-440 package, which was missing. I can't say for sure that this bug is also caused by a faulty Nvidia driver installation, but it looks like it. If someone can tell me where I can report this issue, I'll gladly make it (if it hasn't been reported yet). Once again, sorry for spamming this bug report. Feel free to delete some of my comments, as I don't feel they're really useful. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nvidia-prime in Ubuntu. https://bugs.launchpad.net/bugs/1877727 Title: Nvidia dGPU active despite prime-select set to Intel card Status in nvidia-prime package in Ubuntu: Confirmed Bug description: After fresh installation of Ubuntu 20.04 I changed used card to Intel GPU with command "sudo prime-select intel". After reboot Intel card is used to display, but dGPU is still active (more heat and power consumption, this laptop also has led that indicate dGPU activation). In Ubuntu 19.04 which I used till today, after change to iGPU, laptop use iGPU and dGPU is in inactive state. I have MSI PE70 7RD laptop with Intel 7700HQ processor and NVIDIA 1050 GPU. I found similar problem on net, but without solution. https://askubuntu.com/questions/1232461/ubuntu-20-04-dgpu-is-always-on Workaround that I found is use "powertop" and in Tunables card activate power saving for dGPU card "Runtime PM for PCI Device NVIDIA Corporation GP107M [GeForce GTX 1050 Mobile]", but I think it should work without such changes every reboot.
