[Bug 212800] Re: no brightness-control on samsung laptop
so finaly i was able to fix somthing in backtrack 5 r3 on Samsung N150 netbook , actually its a fix for all ubuntu users , its the backlight issue which is really irritating kept searching it for 2 months with no hope until 30 minutes ago , it took 4 hours of searching and reading , linux has issues with Samsung ACPI , my netbook has intel 3150 GPU it installs the driver perfectly but you will not be able to control the brightness , there was a fix provided by "voRia" called "samsung-backlight" , claiming to fix the problem on ubuntu 9.04 and 10.04(which back track is based on) , still didnt fix it , so my fix is going to the terminal and writing the following command: echo 4 > /sys/class/backlight/samsung/brightness . as the number determines the level of brightness and it was from 0 to 8 levels , i tried to put it in the panel as launcher but it only works in terminal , i wish if someone could tell me how to assign a command to a keyboard , like if i can assign it to the brightness shortcut key on my netbook that originally was made for windows acpi brighntess control , also i noticed if i removed the intel driver and rebooted the brightness control works natively with FN keys but when i bring back the driver it doesnt , so im guessing its a problem in the driver it self ,finally i want to say im not an expert in linux and i thought this might be a contribution -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/212800 Title: no brightness-control on samsung laptop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/212800/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 212800] Re: no brightness-control on samsung laptop
The brightness control works in any Samsung laptop starting with Oneiric (it introduced the new samsung_laptop kernel driver). Therefore I'm marking this bug as fixed. However, please note that the backlight flickers in Oneiric until bug 810093 is fixed. The flickering can be stopped by changing the baclight brigtness. Further workarounds and more details cas be found from that bug.

The Samsung R560 has the same problem, but I have a partial work-around. If you press Fn+Up/Down, the brightness bar appears and starts flickering, but the brightness does not change. Instead the keyboard seems to lock up. You can return the keyboard to normal by pressing Ctrl-Alt-F3, then Ctrl-Alt-F7 The Gnome brightness control applet also does not work. However, you CAN adjust the brightness from the terminal, with the following commands: For full brightness, type: smartdimmer -s 100 for low brightness, type: smartdimmer -s 30 I placed a set of script files with these commands on the desktop.

[Bug 212800] Re: no brightness-control on samsung laptop
Hi all, I just experienced the same situation as Tobias Plug described. Bascially with 8.04, the brightness control was marked "not avialable" under Gnome... now it is somehow available, but locking some part of the keyboard and the menu display. So I decided to investigate a little bit more: First of all this does not come from 'hotkey-setup'. I simply uninstall it, rebooted and guess what, same issue. I then took a look to all the running processes, killing all the suspicious ones. Then I came to the 'gnome-power-manager'. As the process is automatically re-launching itself, I also de-install it and then, no problems at all: - brightness hotkey are not working anymore (same behaviour as 8.04) - sound hotkeys are still working perfectly. So I guess that there is a slight bug in 'gnome-power-manager' package. -- no brightness-control on samsung laptop https://bugs.launchpad.net/bugs/212800 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

@ Tobias: can you please tell which graphics hardware your q45 has (intel/nvidia)?

I am running 8.10 on a Samsung Q45. The brightness control now works somewhat but is still bugy. At first attempt I could change brightness just fine, but then the keyboard seemed to be dead. X did however receive ctrl-alt-1 and after switching to a tty and back the keyboard input is working fully again. Now however when I try changing the contrast hitting FN-[brightness-up] or FN-[brightness-down] it seems to receive multiple invocations and hence turns the brightness all the way up or all the way down. please let me know what additional information I can provide which might of of use. -- no brightness-control on samsung laptop https://bugs.launchpad.net/bugs/212800 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

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test: 1) If you are comfortable installing packages on your own, the linux- image-2.6.27-* package is currently available for you to install and test. --or-- 2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD. Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel.
