Subject: [gentoo-user] Where does /sys/class/backlight/intel_backlight come from?
Date: Fri, 16 Mar 2012 13:14:01 -0700 [thread overview]
Message-ID: <CAN0CFw2+yrNn03fazU4HSwAUpDNfN47xmzvVTa-zScXE2iQ+7g@mail.gmail.com> (raw)
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?
