Does anyone know which kernel option would be responsible for /sys/class/backlight/intel_backlight? I've disabled some backlight stuff in the kernel but the directory still appears. I get screen backlight control on my laptop if I do:
echo 0 > /sys/class/backlight/intel_backlight/brightness but if xlockmore blanks my screen, I have to issue the above again before screen backlight control works again. I also have acpi_video0 in /sys/class/backlight and I think removing intel_backlight might fix the problem. I could try deleting the directory. Is that safe? Are the files and folders in /sys generated dynamically at boot? - Grant
