I am experiencing the same problems on my Samsung P55-Pro, which
indicates that these models probably handle those things in a similar

I can add something to the backlight problem: When resuming from suspend
to disk the backlight usually is not at full brightness, but when booted
with ac plugged in it can be set to full brightness. However, I cannot

Also the brightness indicator that seems to come with gnome always shows
that the brightness is at 0 percent when trying to change it, even
though the brightness is at maximum.

model that also works with yours or vice versa.
