[Bug 1778011] Re: SRU: PRIME Power Saving mode draws too much power
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 :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 Desktop Bugs, which is subscribed to gdm3 in 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 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

> * If I understand correctly, the bug does not occur in Ubuntu 18.10. The user can switch seamlessly between using the Intel or the Nvidia discrete graphics card. Is this correct? @jespestana No, this bug is affecting me on 18.10. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gdm3 in 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 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

I can confirm that installing nvidia-390 through the Ubuntu driver dialog, and then using nvidia-settings or prime-select to set intel keeps the nvidia card on for me on my GeForce 840M laptop. I can also confirm Installing bbswitch-dkms and turning it off through bbswitch works. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gdm3 in 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 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
