Anyway, I am attaching both gpu-manager.log and gpu-manager-switch.log for when both the Nvidia profile and Intel profiles are selected. FWIW, I discovered that once I select the Intel profile I can use bbswitch to shut the card down for full power saving. This behavior remains constant regardless of whether I have TLP running or not. Powertop shows the Nvidia card tunable set to "Good" even without TLP running. As far as I can tell, the issue seems to be that on my hardware the only way to shut the card down completely is through a dedicated ACPI message (i.e., what bbswitch does) rather than "normal" PCIe power management. Let me know if I need to do anything else, this laptop is not essential for productivity so if I need to try to break stuff I'm up for that. ** Attachment added: "gpu-manager-logs.tar.xz" https://bugs.launchpad.net/hwe-next/+bug/1778011/+attachment/5233964/+files/gpu-manager-logs.tar.xz -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-settings 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 _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
