On reboot it broke lightdm and I had to jump over to another tty and rm the file I tried to alter there file's BusID to something i saw from inxi -Gxx but that caused issues. I tried adding nf to my /usr/share/X11// using the same values from the link thread but that doesn't appear to change anything. Setting kernel parameters to acpi_backlight=vendor or acpi_backlight=native remove acpi_video0 from /sys but the brightness level persists after reboot. I CANNOT set /sys/class/backlight/intel_backlight/brightness with echo even though ls -l says root has write permission I must have over looked something because I CAN set /sys/class/backlight/acpi_video0/brightness with echo as root and it DOES change my brightness level! I don't seem to have that, and it would make sense seeing as i have intel_backlight in my /sys

I see in your linked thread that the person had a nf file in the X11 config stuff. Previously I had this same model and used BL Helium on it, and could swear that the brightness controls worked, but that was well over a year ago now.

This particular laptop is new to me and has only had this linux install on it. Weird thing, I cannot echo in a change to these files even as root There are a few that do not, such as touchpad toggle, and a few i don't recognize the symbols of.Įdit: I should stress, the keys and slider function and register a change in the /sys/class/backlight/intel_backlight/actual_brightness, but this change does not produce any results on the screen's brightness values for /sys/class/backlight/intel_backlight/actual_brightness change when using the either the Fn Keys or the Slider, but the screen brightness does not actually change.

Some of the other functions keys DO work, at least the ones I would commonly use, Volume control, numlock, wifi toggle. I'm running vanilla Lithium here with xfce4-power-management starting at boot Video 40960 2 the Fn keyed brightness controls and slide bar do NOT effect brightness of the screen.
