Prime select is not turning off the dgpu in Ubuntu 20.04 Laptop: MSI GE40 dGPU: GTX 760m iGPU Intel HD4600
Driver: Nvidia 440 installed via "Additional Drivers" GUI from default 20.04 repos. When using "prime-select intel" the iGPU is being used however the dGPU is still powered on resulting in considerably more power usage and heat generation. Installing and loading the bbswitch module and running "echo "OFF">/proc/acpi/bbswitch" does successfully power down the dGPU drastically lower power usage. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1765363 Title: prime-select intel is not powering off the nvidia card To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-prime/+bug/1765363/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
