[Desktop-packages] [Bug 1765363] Re: prime-select intel is not powering off the nvidia card
I can confirm the same issue on 18.04 using Gigabyte AERO 15x v8 with Nvidia GTX 1070 MaxQ. The `prime-select intel` method leaves the card powered on, even though the vgaswitcheroo/switch indicates it's off - the system power draw is ~ 20W. After installing bbswitch and turning the card off that way (had to mask off the nvidia-fallback to prevent manual loading of the nouveau module), the power draw drops to ~ 10W so the card is indeed powered off in that case. There is something broken in nouveau driver for my system as it is unable to power down the card using the vgaswitcheroo method, when running with nouveau.runpm=0. -- 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/1765363 Title: prime-select intel is not powering off the nvidia card Status in nvidia-prime package in Ubuntu: Confirmed Bug description: Right now, it seems that prime-select intel makes sure the nvidia driver is not loaded, as nvidia-settings reports. But my power consumption is > 20W. cat /proc/acpi/bbswitch reports the card is still on. If bbswitch and powertop are reliable, then the nvidia card is still powered. This is a thinkpad w520 in Optimus mode.
