You are right!
The 2:2.99.917+git20160706-1~bpo8+1 release works fine but not
2:2.99.917+git20161105-1~bpo8+1.
So it is really a regression on the last release.
Perhaps a wrong choice of the best iface or about, or other thing.
My system have two backlight interfaces:
/sys/class/backlight/eeepc and /sys/class/backlight/intel_backlight
The first is safer but the second permits atomic variations of the
backlight.
Thank you.
