After seeing Alex's post, I tried installing 410.104-0ubuntu0~18.10.1 from ppa:graphics-drivers. Using 4.18.0-16-generic kernel.
I find that when I use Intel profile, powertop reports the nvidia card as 0% active, and the setting in Tunables shows up as Good. However, /proc/acpi/bbswitch reports as 0000:01:00.0 ON, and the *fans* are spinning. Turning the graphics card OFF with bbswitch, the fans stop spinning. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1778011 Title: SRU: PRIME Power Saving mode draws too much power To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1778011/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
