[Impact] System can not keep the brightness value, after reboot/poweroff the brightness will still be highest. [Fix] Suggested by Nvidia, we need to run nvidia-persistenced.service before systemd-backlight@backlight:nvidia_0.service [Test Case] Adjust the brightness value, reboot, the value must keep persistence during boots. [Regression Risk] Low, this fix is just adjust the systemd order more earier. https://github.com/hugh712/nvidia-graphics-drivers To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/1885087/+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
