This bug is awaiting verification that the linux-nvidia- tegra/6.8.0-1001.1 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-noble-linux-nvidia-tegra' to 'verification-done-noble-linux-nvidia-tegra'. If the problem still exists, change the tag 'verification-needed-noble-linux-nvidia-tegra' to 'verification-failed-noble-linux-nvidia-tegra'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

Related kernel fixes are to be released in v6.9. [Fix] Two linux-next committed fixes are required. The first one introduces panel_power_savings sysfs entry itself, and the second one extends abmlevel sysfs entry to allow an auto mode. [Test Case] 1. Check existence of panel_power_savings sysfs entry: $ cat /sys/class/drm/card0-eDP-1/amdgpu/panel_power_savings -1 2. Remove power cable and switch between power profiles from Power Management settings. The content of above panel_power_savings sysfs entry should be updated correspondingly. [Where problems could occur] While the abmlevel entry now has a different default value that allows automatic power management, the behavior may differ from users' expectation. [Other Info] power-profiles-daemon >= 0.20 is only available on Noble or later at this moment, so only Noble/Unstable will be nominated for fix. ========== original bug report ========== Required kernel fixes (in linux-next): * https://gitlab.freedesktop.org/agd5f/linux/-/commit/63d0b87213a0ba241b3fcfba3fe7b0aed0cd1cc5 * https://gitlab.freedesktop.org/agd5f/linux/-/commit/040fdcde288a2830edc31dd507963d6aadf990d2 See also power-profiles-daemon merge request https://gitlab.freedesktop.org/upower/power-profiles- daemon/-/merge_requests/137 To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/2056716/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
