On disk, the backlight brightness is stored in\n/var/lib/systemd/backlight/. During loading, if the udev property IDBACKLIGHTCLAMP is not\nset to false, the brightness is clamped to a value of at least 1 or 5% of maximum brightness,\nwhichever is greater. This restriction will be removed when the kernel allows user space to\nreliably set a brightness value which does not turn off the display.\n\n## Sections\n\n- **NAME**\n- **SYNOPSIS**\n- **DESCRIPTION**\n- **KERNEL COMMAND LINE**\n- **SEE ALSO**\n\nUse structuredContent.sections for detailed options, examples, and full documentation.\n"
