** Description changed: systemd-backlight saves the brightness value right before shutdown.target, however it doesn't work because the nvidia_0 backlight sysfs disappears after GFX device is closed by Xorg, long before shutdown.target. [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
