You realy should report such issues to upstream, since we can not do
*anything* about such issues.
@Andreas and Michael:
Any ideas what we can do to avoid so much upstream-only related bug reports?

Some further information (copying from a report erroneously filed to the
linux-image package).
At first I could not control backlight at all.
Then, following forums and wikis on the net i tried to pass the
acpi_backlight=vendor parameter to the kernel, and now it works... a little
bit.
What works is that all methods, the keyboard special keys, xbacklight,
gnome-
control-center, all udpate the same file, in my case
/sys/class/backlight/samsung/brightness.
But. First that file is reset to the maximum value at every restart. I
worked
around this by echoing something into it in /etc/rc.local.
Second, and worst, when I change the file value at runtime (by any of
the above
methods), the value is applied... sometimes. I mean, I keep changing the
value
and once a in while the brightness changes, after 2, 5, 10 seconds, and
I have to
be lucky that it happens at the right brightness. If you just change the
value
without keeping trying, the value is not usually applied.
Regards, Carlo.
