Package: xbacklight
Severity: normal

xbacklight -set sometimes has no effect. For example, when I suspend and
resume my laptop, the backlight is reset to 100%, but is still reported
as whatever I set it to before. xbacklight seems to do nothing if I try
to set it to the same value; instead, I must first set it to a different
value.

That sounds like a bug in your video driver reporting wrong values.
If this is still an issue please open a bug against the video driver
with the output of "xrandr --verbose" before and after suspend, and
output of "grep -r . /sys/class/backlight/*/" (and your X log).
