Anyway I checked the values that systemd stored and they look as follows: # cat /var/lib/systemd/backlight/pci-0000\:00\:02.0\:backlight\:acpi_video0 100 # cat /var/lib/systemd/backlight/pci-0000\:00\:02.0\:backlight\:intel_backlight 11 So the value in intel_backlight is certainly incorrect - the above values were checked after KDE resets the brightness correctly. So the numbers in the /sys/ area are set right but on shutdown it seems that the saved values by systemd are wrong: # ls -1 /sys/class/backlight/*/*brightness | xargs -I % sh -c "echo % ; cat %" /sys/class/backlight/acpi_video0/actual_brightness 100 /sys/class/backlight/acpi_video0/brightness 100 /sys/class/backlight/acpi_video0/max_brightness 100 /sys/class/backlight/intel_backlight/actual_brightness 937 /sys/class/backlight/intel_backlight/brightness 937 /sys/class/backlight/intel_backlight/max_brightness 937 These values are not getting saved by systemd but the intel value is somehow becoming 11 instead of 937</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
