I have a sony vaio VGN-NW270F.Everything is working fine except the FN brightness keys, they are mapped to F5 and F6. If anyone knows the solution to this problem or could provide me with a way to map different keys to control the brightness of my monitor that would be great.

View 9 Replies View RelatedIt seems that the brightness applet of Maverick has some bugs. I can adjust the brightness of my laptop using the Fn keys, but the notification bubble does not appear. (You know, the one that appears at the upper right hand corner of the screen when you get notifications.) Also tried adding the brightness applet to a panel, but does nothing when I try to fiddle with the slider. And one more thing, when I unplug my laptop from the power adapter, it doesn't scale down the brightness automatically, the same way when I plug it back in, the brightness doesn't scale up.
View 2 Replies View RelatedI've been using Ubuntu 10.10 64-bit on my MacBook Pro 5,5 for about a week now. And I've noticed that the screen brightness adjustment does not work. When I click the F1 and F2 buttons I get the notification that it's changing but it doesn't actually change it. So I added the brightness adjustment to the panel and it won't let me move the toggle thingy. Has anybody else had this problem? All my other F keys work fine.

D:I can't stand this, it's like my screen is stuck on supa-bright and it's hurting my eyes. When I load my PC up in Windows, the brightness control works just fine. But it doesn't seem to work on Ubuntu.
View 9 Replies View RelatedI have installed Xubuntu 11.04 on a HP Probook 4510S and the FN Keys of brightness only works when I on the login screen (gdm). Until I enter to my desktop the FN Keys stop Working. This is a XFCE Issue? I have another Laptop, a IBM THinkpad X40, with the same Xubuntu 11.04 and the FN Keys works perfect! Even the keyboard light Works! I think this is a ACPI related problem, I google it the problem with out a specific issue like this. The only thing that I can do it is use of xbacklight when I'm on my session.

I have an Asus P50IJ-X2 and in lucid the backlight cannot be adjusted. The panel app doesnt work, when I click on it and try to adjust the slider it just disappears. When I reopen it the slider is at the top left corner of the screen.
The function keys seem to be detected alright, but when I press them I get the notification that the brightness is going down but nothing happens. Also after the first press the notification gets extremely laggy. If I press the brightness keys again it takes 30 seconds or more for the notification to show up. Also after the first press my volume function keys have the same behaviour in the notification area as the function keys.
Also messing with the controls in the power settings doesn't do anything. The strange thing is all of this worked perfectly in Karmic. The function keys, auto dimming, everything just worked out of the box. I have no idea where to start trouble shooting this so can anyone give me some direction?
I looked through the wiki and for some reason I cannot get my brightness controls to work.

The brightness FN keys change the slider but make no physical difference of the brightness. And the microphone just doesn't work.

SOLVED (for my laptop at least - Acer Aspire 5740)
The trick was to add "acpi_osi=" (without the quotation marks) to the GRUB parameters. Setting the parameter to an empty string means that no OS is reported to the BIOS. By default acpi_osi is set to Windows NT. I had previously tried "acpi_osi=Linux" but it didn't work, apparently it had to be an empty string.The brightness keys work now I think it might work for other models as well if they have core i3 processors.
I'd been trying to get into Linux before I bought it so I figured that I would try to get it onto my new Mac so that I could use it wherever I am. I decided to try Debian Lenny 5.0.3 a whirl after reading about all the different distros available. I've successfully installed it and I can get to it with rEFIt, and I have quite a few things working such as the video drivers and wifi. However, I've had trouble getting it to a level where it'd be usable away from home. Here are the main problems I'm worried about:
1) I installed pommed but I still can't use the brightness keys to change the screen brightness. I'm not sure if there's some other workaround for this?
2) I tried some recommended power management packages (gnome-power-manager) but it doesn't seem to be accessible or functional right now. I don't have any way to control it or get to it that is obvious to me. Is an icon or anything supposed to appear on the task bar when you install or what? Getting some sort of power management on here is important because it gets really lousy battery life otherwise.
3) Being a Macbook, there's no right-click button. Multitouch would be really nice (two-finger scrolling!) but I'd be OK with ANY way to right-click with the touchpad. I have a wireless USB keyboard/mouse combo that works at home at least . . . right out of the box too!
4) I've seen some packages called the Mactel PPA, but they are made for Ubuntu. Since Debian and Ubuntu are so similar, is there any way to make those work on Lenny? I think that if I got those to work, I could fix some of the problems above. Or do I have to install Ubuntu?
5) I just noticed that the sound doesn't seem to work yet either.
Recently I tried putting Kubuntu Natty Narwhal on yet again and to my surprise it mostly worked. The only major thing wrong with it was my brightness controls didn't work (I have a VPCCW21FX laptop) at first this was an anoyance being blinded by my screen but I soon realized that it was killing my battery life. So having tried to seek help in getting it to work I tried out OpenSUSE. They worked! but as soon as I updated the kernal they no longer worked. No Problem. I reinstalled and told it to never apply that update. Then I installed the official nvidia drivers via repository on the opensuse wiki. they installed and worked but my brightness controls were once again broken.

I'm having a really strange problem, when I turn on openSUSE, the brightness is fine.owever, as soon as I log in the brightness gets obnoxiously low. I have a MacBook Pro 7.1 with openSUSE 11.4 KDE
View 5 Replies View RelatedFirst: When I try to edit my brightness it doesn't work at all. I can turn the LED on/off but when I do up down it brings up the status bar and nothing changes. Asus K60IJ T4400 is my laptop.
The other 'problem' is the MP3 codec? How do I install this? I'm trying to use my Mp3 files in Rhythm box but can't find out how. =[Why does it have to be different ;(
I have an Acer 4810T laptop with Intel graphics. I run openSUSE 11.3, and am about to upgrade to 11.4. But both systems still have a very bad bug with screen brightness. The Fn+Arrow keys do change screen brightness, but after using them the system is rendered extremely sluggish and unresponsive. This sluggishness is most pronounced with a very important Wine app I need to use. The only way to fix the sluggishness is to reboot. With 11.4, the problem is worse because the system boots and automatically partially dims the screen, thus making it even more necessary to change the brightness. Neither Gnome nor KDE are able to change the brightness via their power managers. This means that I can't dim my screen automatically upon disconnecting the A/C power.
I have read many experiences from Ubuntu and openSUSE users, who all have the same problem. I have tried both intellegacy and the new intel drivers, and they both have the problem. I have read that some users have improved the situation by upgrading or downgrading the BIOS. Others have been experimenting with kernel patches:

I am currently using Windows 7 but I would really like to install the new Ubuntu, what bothers me is that I tried using Ubuntu 9.04 few months ago and I had troubles changing the brightness (Toshiba L40). I have searched in the forum and it appears that there are quite some people with the same problems, of course fixes are offered but as at least some basic kernel knowledge is required I am in no position to follows the proposed steps. Since this is one of the determining factors whether to stay with Windows or go to Ubuntu I was wondering whether this problem is fixed in 10.04 or not?
P.S. I haven't tried messing with the kernel because I have only one laptop and I am afraid to lose the information on it.
I just recently installed Xubuntu 11.04 and I want to adjust the brightness levels. I tried using the corresponding buttons on my laptop, but they aren't working. Where can I find the brightness settings on the OS?
I tried this thread: [URL] , but "Power Manager" didn't have that setting.
I want to pick up an obviously unsolved problem. I have a Samsung Q210 Seven Notebook and recently installed Kubuntu. Everything works fine, as long as I put on my sunglasses when working with the notebook in the evening. Triggering the hotkeys shows an icon with a percentage counter that increases or decreases, depending on which function key I use. Although this looks really nifty, it gets boring after utilizing a few times. And, as you might already think, the brightness doesn't change here...
I found a hint telling to adjust the /etc/default/grub: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset acpi_backlight=vendor"
The only effect this has is that the nice percentage lowering/raising minigame doesn't work anymore
Also, nothing from the suggestions from the previous post work. This is really bad, since that way not only the user's eyes suffer, but also the energy consumption of the display is maximized.
how I can change brightness/backlight intensity
I took the courage yesterday to install ubuntu 9.10. Internet was working absolutely fine (wireless), but brightness controls were not working (they still don't). So I went to this page https://wiki.ubuntu.co/Hotkeys/Troubleshooting, and ran following command(s) killall gnome-settings-daemon gnome-power-manager Now since then I cant get the internet working, and cant see the wifi connection on task bar. I have restarted the laptop but no avail.
PS: any help on how I can reduce the brightness of monitor. I am using SONY VIAO VGN FZ38M, with Nvidia 8400M GT. I have tried several threads and tried all sorts of things, like xbacklight, or somthing to do with sudo .VGA/LCD/brightness.etc.
I cannot adjust the screen brightness in the power management menu. I can access the window and move the scroll bar, but there is no change.
I am on v 10.04 32bit , a Benq joybook s35.
It was working just fine on the previous version of ubuntu.
I have a fairly new Samsung 2233RZ 120hz lcd hooked up to a GeForce 8800gt...
When i click on the Brightness and Contrast controls on the monitor it gives me "Not available"...
Does the linux nvidia drivers disable my monitor functions? is my monitor improperly configured? do i need to take some steps in setting up my monitor? there are some tiny white scanlines going through the display horizontally if i look real close...minimimalist ubuntu 10.04/XFCE4 same happend on ubuntu 10.04 gnome... with or without the geforce drivers.
Problem with lowering brightness and increasing it, When I press button to lower brightness it doesn't remember, but when I set it with power management it is fine.

View 1 Replies View RelatedI am using Samsung N150 and ubuntu 10.10 is installed in it. There is problem with brightness control i.e., I cannot control my brightness by up & down keys. I made settings such as:
I Add the repository to the sources list and enable it
sudo add-apt-repository ppa:voria/ppa
Perform complete system update
sudo apt-get update && sudo apt-get upgrade
it may take long time depending the internet connection
than I installed packages "samsung-backlight" and "easy-slow-down-manager"
sudo apt-get install samsung-backlight easy-slow-down-manager
Also I made changes in brightness setting in during the boot i.e set to user control instead of automatic. But after doing all these stuff still my laptop brightness not control by fn + up/down keys.
My computer (Samsung R580 N330M)seems doesnot adjust brightness both power manager and configuration file in /proc, I tried NVIDIA setting and it works,but I think it changes the color,not LCD. is it caused by driver problems?

View 3 Replies View RelatedI have installed Ubuntu 11.04 for the 1st time. Before, I used Windows 7. I've got a Samsung R418 Laptop and on my laptop the brightness level is too low.. When I plug in the charger, the brightness level is good. I used the Fn up/down key to increase and decrease the level of brightness, but didn't work. I even checked the Power Management section, but didn't work. Installed an app called Ubuntu Tweak which allowed me to increase the level of brightness when on battery, but that too didn't work out.
Also tell me what to do and where to do it from, since I'm new to Ubuntu
