Brightness control works for me on my N150P in both F19 and F20. It just doesn't preserve brightness level when suspended. I attach lshw of a Samsung NC10 that seems to have the same VGA. On LXDE keybutton combo for brightness does not work. Only #setpci -s 00:02.0 F4.B=ff manages to change to maximum level the brightness localhost.localdomain description: Notebook product: NC10 vendor: SAMSUNG ELECTRONICS CO., LTD. version: Not

Hi, Thanks for the info. Can you try booting with "acpi_backlight=vendor" on the kernel commandline ? To do so, reboot then at the grub bootloader screen press ESC, then e to edit the current entry, then go to the long line with all the kernel parameters, and add the end add a space followed by "acpi_backlight=vendor" and then press ctrl+x to boot with the new cmdline. Once booted in a terminal do "cat /proc/cmdline" to verify that the "acpi_backlight=vendor" is there. If it is try to change your backlight brightness. If this works please also try suspend / resume plugging in / out the power adapter, etc. Then report back here how things went for you. If everything went ok we can add a quirk for this laptop to do the acpi_backlight=vendor behavior by default. Regards, Hans Hi again, I've been looking a bit more into the relevant kernel code. Can you please run the following commands and provide their output: lsmod cat /sys/class/dmi/id/sys_vendor cat /sys/class/dmi/id/product_name cat /sys/class/dmi/id/board_name And can you also do (as root): modprobe samsung-laptop And then run "dmesg > log" and attach the generated log file here ? Thanks, Hans One last remark, re-reading the bug report, it seems that originally you filed this bug using a Samsung N150P. but now you're testing with both an NC10 and NC210, correct ? Can you please provide the info I've requested for both models ?

To retrieve info from those computers I have to contact > their owners so it will require some days. Ok, so some background info, it seems that the acpi_video brightness interface is broken on quite a lot of samsung netbook models. Since if it present it gets preferred over Samsung's own vendor firmware brightness code, this breaks brightness control on these laptops. To fix this we've a blacklist with systems on which not to use acpi_video's brightness control, this blacklist lives here: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/drivers/platform/x86/samsung-laptop.c#n1438 So the solution is (very likely) to add the laptops you've access to which show this problem to this list. Note that the N150P is already there, so that one should no longer show this problem. For the others please try booting with acpi_backlight=vendor on the kernel cmdline, check everything works as advertised that way and then do: cat /sys/class/dmi/id/sys_vendor cat /sys/class/dmi/id/product_name cat /sys/class/dmi/id/board_name And add the output of those commands here (like you already did for the NC210/NC110). Let me know when your list of laptops needing such a quirk is complete, then I'll write a kernel patch and do a test kernel build with that patch for you to test. Hi, While waiting for info on the other models, I've gone ahead and created a patch to add a quirk for NC210 to the samsung-laptop driver. I've just started a kernel (scratch) build with the patch added: http://koji.fedoraproject.org/koji/taskinfo?taskID=6803021 Note it is currently still building. Can you please give this build a try, it should work without you needing to specify any kernel cmdline parameters. If you can confirm that it works I'll send the patch upstream ASAP. Regards, Hans The problem is that I don't own that netbook, I have putted my hands on it because I installed Fedora on it. Now I contact the owner hoping that he will apply the test kernel without much troubles :) Brightness control doesn't work on N145P with 3.15.* kernels. Echoing a value into /sys/class/brightness/intel_backlight/brightness works. However, acpi_backlight=vendor doesn't seem to help. Hi Vratislav, (In reply to Vratislav Podzimek from comment #18) > Brightness control doesn't work on N145P with 3.15.* kernels.

Can you please read and walk through: http://hansdegoede.livejournal.com/13889.html And then file a new bug (with me in the CC) ? Thanks, Hans kernel-3.14.3-200.fc20 has been submitted as an update for Fedora 20. https://admin.fedoraproject.org/updates/kernel-3.14.3-200.fc20 Package kernel-3.14.3-200.fc20: * should fix your issue, * was pushed to the Fedora 20 testing repository, * should be available at your local mirror within two days. Update it with: # su -c 'yum update --enablerepo=updates-testing kernel-3.14.3-200.fc20' as soon as you are able to, then reboot. Please go to the following url: https://admin.fedoraproject.org/updates/FEDORA-2014-6122/kernel-3.14.3-200.fc20 then log in and leave karma (feedback). kernel-3.14.3-200.fc20 has been pushed to the Fedora 20 stable repository. If problems still persist, please make note of it in this bug report. kernel-3.14.3-100.fc19 has been submitted as an update for Fedora 19. https://admin.fedoraproject.org/updates/FEDORA-2014-6167/kernel-3.14.3-100.fc19 kernel-3.14.4-100.fc19 has been submitted as an update for Fedora 19. https://admin.fedoraproject.org/updates/kernel-3.14.4-100.fc19 Will the fix be putted in upstream, to fix other distro too? Hi, (In reply to Germano Massullo from comment #25) > Will the fix be putted in upstream, to fix other distro too? Yes, that is the plan, as soon as you can confirm that the fixed Fedora kernel fixes the problem without needing any kernel cmdline options. I'll send the patches upstream. I'm also still awaiting testing results for the NC10, so that I can write a patch for that too. Regards, Hans kernel-3.14.4-100.fc19 has been pushed to the Fedora 19 stable repository. If problems still persist, please make note of it in this bug report. ping, I'm still waiting to hear from you if the kernel I gave you fixes the problems on the NC210/NC110 model, so that I can push the patch upstream.

I assume that the output you've provided is with acpi_backlight=vendor on the kernel commandline ? Can you please walk through the debug steps provided here ? : http://hansdegoede.livejournal.com/13889.html I specifically want to know if the brightness osd shows when you press the keys and if not which devices evemu-record shows, and if any of them show brightness keypresses.

If you run 'lspci', there should be a "VGA compatible controller" device and that ID is its Bus ID (the first column).

While both are about the NC10. Also in comment 30 you write that both backlight interfaces work, so if comment 30 and 37 are right, then everything should just work. Can you please: 1) boot the system without any special kernel commandline parameters 2) redo your tests from comment 30 3) redo your tests from comment 37 4) describe exactly what happens when you try to change the brightness using the keys will logged into the desktop environment. 5) let us know which desktop environment you're using. Note I need answer to all 5 items to be able to help you further, please provide an answer to all 5 in your next comment.

I think that in comment 32 I choosed the wrong input for evemu-record, so I got no outputs while pressing FN keys.

NC10 dmesg for each kernel boot option
Hi Germano, Thanks for all the tests and logs. Looking at the test results, both the keys, and the actual brightness controls seem to work fine. The problem seems to be that the lxde environment simply lacks support for listening to the brightneskeys, and adjusting the brightness when the brightness keys are pressed.
