Hi all, I have some issues with my backlight and I"ve chased down a lot of leads with no real luckl. I am currently on 6.0 kernel and if I upgrade to 6.1 and set acpi_backlight=video as a kernel paramter the fn keys change the brightness aga

The problem is on both 6.0 and 6.1 if the machine goes into sleep (STR I am guessing) I lose control of the backlight when I wake it back up. Something still seems to have some control though because if I go into settings and change "screen dim" to "1 minute" and wait, the screen will then dim a little further which is impressive because it's already almost too dim to read. It's my understanding the 11th gen Intel Processors have S0Ix sleep state and I am wondering if this is causing ACPI issues, but I am having trouble tracking down what exactly is happening on re-log. Anyone have similar issues and managed to get everything in proper order?'
