It was certainly working with 5.4.0-* from 20.04 at some time, I have been mainly using dGPU for 2-3 months, and wouldn't have noticed any regressions.
Strangely, I tested with 5.4.0-56-generic that remained after the upgrade, and it is also not powering down dGPU. 20.10 didn't upgrade nvidia driver, I currently have 450.80.02 Something important I just noticed, at 19.10 and 20.04 nvidia vga and related audio function devices weren't visible at lspci when booting with intel gpu only, but after upgrading to 20.10 they are visible again when booting with intel gpu. I suspect this mechanism was essential for power management and it has changed with 20.10 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1907212 Title: Power consumption regression after upgrade to 20.10 5.8.0-31-generic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1907212/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
