I posted this issue on askubuntu, but no one has been able to help so far. My problem is that the brightness level on my laptop will never save and apply after reboot. Please refer to the link for further details, but I will summarize it here. I created a /usr/share/X11/xorg.conf.d/80-backlight.conf file, but all the information in the file is for intel. Like so
Identifier “Intel Graphics”
Option “AccelMethod” “sna”
Option “Backlight” “acpi_video0”
How can I find the information I need to fix this and have the screen brightness start working so that I don’t have to adjust it after every reboot.
