Just updated Devuan Ceres today and found the display being blanked during
the boot process. I was able to recover over SSH using

% brightnessctl
Device 'intel_backlight' of class 'backlight':
        Current brightness: 0 (0%)
        Max brightness: 512


% brightnessctl set 100%
Updated device 'intel_backlight':
Device 'intel_backlight' of class 'backlight':
        Current brightness: 512 (100%)
        Max brightness: 512


Yet running '/etc/init.d/brightness start' blanked the display again. This
is due to:

% cat /var/lib/initscripts/brightness.intel
0

I have no idea how this value got into this file. The display was certainly
not at 0% brightness as I rebooted after the update.

Expected result:

Never ever blank the display on boot even in case
'/var/lib/initscripts/brightness.intel' contains the value zero.

Just don't.

Expected result 2:

Safe the right value to '/var/lib/initscripts/brightness.intel'. Zero is
definitly not it.

If I run:

% echo 512 > /var/lib/initscripts/brightness.intel
% /etc/init.d/brightness start

After sending this bug report I will reboot and see whether it will remember
this value. Otherwise I will 'chattr +i' this file for now.

This is on a ThinkPax X260 with Intel on board graphics from
Intel(R) Core(TM) i7-6600U CPU @ 2.60GHz CPU.

Thanks,
Martin
