Updating the NC10 bios to version 11CA fixes the problem. Alternatively, you can use an additional kernel module which enables the backlight control when KMS is enabled.

I had the same issue on the N130 where it was reported that "No outputs have backlight property". That was with bios rev 00.

[Bug 448885] Re: Samsung NC10 screen brightness up/down function keys do not work
Indeed this patch is already upstream and will land in 2.6.32. Unfortunately the current kernel for Karmic is frozen except for critical bug fixes. As a workaround for now, I'd encourage you to use an upstream kernel for now: http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.32-rc4/ I've pasted the upstream commit id below: ogasaw...@yoji:~/linux-2.6$ git show 1ba36e11b227e32f818aea5b4d84f5cbff71e7db commit 1ba36e11b227e32f818aea5b4d84f5cbff71e7db Author: Dmitry Torokhov Date: Thu Sep 3 17:22:04 2009 -0700 Input: atkbd - allow setting force-release bitmap via sysfs There are more and more laptop requiring use of force_release quirk for their multimedia and other specialized keys. Adding their DMI data to the kernel is not sustainable; instead we will rely on help from userspace (HAL) to do that for us. This patch creates a new 'force_release' sysfs attribute (that belongs to serio device to which keyboard is attached) which can be used to set up force_release keymap. For example, Dell laptop owners might do: echo 133-139,143,147 > /sys/devices/platform/i8042/serio0/force_release Signed-off-by: Dmitry Torokhov ** Changed in: linux (Ubuntu) Importance: Undecided => Medium ** Changed in: linux (Ubuntu) Status: New => Triaged -- Samsung NC10 screen brightness up/down function keys do not work https://bugs.launchpad.net/bugs/448885 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 448885] Re: Samsung NC10 screen brightness up/down function keys do not work
Hi, Just to follow up. If I follow these instructions in the kernel bug #12021 (http://bugzilla.kernel.org/show_bug.cgi?id=12021) and switch off the acpi (acpi=off) then I can control the up/down brightness. However obviously my battery is no longer detected. Changing the BIOS setting between "Auto" and "User Controlled" method of controlling screen brightness doesn't make any difference either. According to bug #12021 the bug was fixed with patch in bug 14052 (http://bugzilla.kernel.org/show_bug.cgi?id=14052) "This bug concerns NC10 only and since the code is in the kernel I am closing it. Please try the patch in 14052 for the more general solution." which is apparently fixed in 2.6.32 "The code is in mainline, will be released in 2.6.32." ** Bug watch added: Linux Kernel Bug Tracker #12021 http://bugzilla.kernel.org/show_bug.cgi?id=12021 ** Bug watch added: Linux Kernel Bug Tracker #14052 http://bugzilla.kernel.org/show_bug.cgi?id=14052 -- Samsung NC10 screen brightness up/down function keys do not work https://bugs.launchpad.net/bugs/448885 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
