Bug#900503: Bug #900503 - xbacklight: Packagely solve the case of intel_backlight
I noticed twice the behaviour which I desribed in message #10 in Debian 10.3
("Buster", the currently stable Debian release) on the same hardware (Acer
Aspire E1-530 laptop), too.
I then applied the same steps as mentioned in message #10 .
This is the first time I rebooted my machine having applied these steps, and so
far the screen's brightness is at 100%.
