When I set the brightness manually, I run the following and see: $ ls -1 /sys/class/backlight/*/*brightness | xargs -I % sh -c "echo % ; cat %"
/sys/class/backlight/intel_backlight/actual_brightness 2219 /sys/class/backlight/intel_backlight/brightness 2219 /sys/class/backlight/intel_backlight/max_brightness 4438 However, when I logout and log back in (or reboot) and run the command, I see: $ ls -1 /sys/class/backlight/*/*brightness | xargs -I % sh -c "echo % ; cat %" /sys/class/backlight/intel_backlight/actual_brightness 4438 /sys/class/backlight/intel_backlight/brightness 4438 /sys/class/backlight/intel_backlight/max_brightness 4438 There is a systemd file which apparently stores the brightness for restoration during reboot. $ cat /var/lib/systemd/backlight/pci-0000\:00\:02.0\:backlight\:intel_backlight 4438 I tried manually editing the file to 2219, but upon logout and login or reboot, the brightness was still restored to maximum and the file was restored to 4438. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
