Ubuntu / Apple :: Brightness Control Doesn't Work?
Nov 23, 2010
According to the Community Documentation for a 6,2 running Maverick, the LCD brightness just "Works." I have mbp-nvidia-bl-dkms and pommed installed, but this has never worked for me.
I Install Ubuntu 9.10 and I can't control Brightness, show brightness popup (Fn+F5F6) but screen brightness don't work, I install NVIDIA Driver Linux-x86_64 version 190.53, modiffed xorg.conf.
I added the Brightness Applet to the top panel, but when I change the brightness, nothing happens. 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.
I've installed Ubuntu 10.10 on my Macbook Pro 6,2 and try as I might can't change the brightness of my screen whatsoever. I cant use "echo 100> /sys/devices/virtual/backlight/nvidia_backlight/brightness" because the folder does not exist. Pommed, when run using "sudo pommed -d" complains with "Failed to access brightness node: No such file or directory".
I have the mbp-nvidia-bl driver installed *only* (removed nvidia-bli because I had seen in other threads that the two conflicted). I've tried searching the forums and the web but nothing is helping me so far. Biggest roadblock for me using ubuntu is having the headache of using a much to dim screen(or currently a much too bright screen)
I have a white Macbook 7,1 and am running 11.04 beta 1. I have worked out almost everything, sound being the main thing that didn't work. The one thing I don't have working is my brightness control -- my laptop always displays at 100%. I tried installing pommed and the dkms package from the Mactel PPA, but nothing works yet. The wiki hasn't been updated to 7,1 for Maverick, let alone Natty.
My MacBookPro5,5 (also known as the June 2009 Unibody MBP) is having brightness problems. Usually, with OOTB Ubuntu, I can control the brightness flawlessly with the keyboard keys labeled F1 and F2 with no problems once I install the nvidia_bl driver. Pommed improves the experience, giving me keyboard brightness.
Since installing yesterday, the brightness control randomly stopped working. Xev reports that the brightness up and down keys return a keycode (whereas F7 - F12, the playback and volume keys do not; both sets control their respective stuff natively)... this shouldn't happen. nvidia_bl is loading properly according to dmesg; so this problem is baffling.
The Gnome brightness applet does not work, nor does auto dimming. The applet displays a helpfully-apt red circle-with-slash mark. "echo x | sudo tee -a /sys/class/backlight/nvidia_backlight/brightness" still works to change the brightness manually. I can get the Gnome brightness working by manually changing the brightness, killing gnome-power-daemon, and then restarting it via the terminal in no-daemon mode.
I'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.
i use a HP Pavilion dv6-3016ax everything works perfectly and i am very happy with ubuntu! If i could get the Brightness keys to work and the microphone i'd be even better. The brightness FN keys change the slider but make no physical difference of the brightness. And the microphone just doesn't work.
First: 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 bought a Toshiba Nb205 laptop with a Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02) inside. After I first got it I installed Ubuntu onto it, and that's where the problems started. After everything was installed I noticed that my sound doesn't work. So I looked everywhere. I tried so many solutions offered on these forums including messing around with Alsamixer and nothing seemed to be working. Then one day I luckily stumbled upon this website that directed me here: [URL] So I went there and picked the Linux 2.6(X86)(DEB) from the drop down list and installed it. I rebooted my machine, and I now had sound.
However, the only problem is that I can't control the volume of the sound. When I play something, it stays at one volume and one volume only. Nothing on sound preferences will work. The only way I can raise or lower the volume is if I do it in the application that I run, like if I am playing a ..... video, I have to use their volume control to control the volume. My master volume won't work at all.
after installing trying to install veetle on my ubuntu 10.04 64 bit I always get the message at the start-up:could not update /home/user/.ICEauthority.my sound control does not work anymore (message: 'waiting for sound system to respond')using Krusader I get the message 'Cannot talk to klauncher: The name org.kde. klauncher was not provided by any .service files.I checked the owner of .ICEauthority and the permission and they are OK. Same for my /home. None of the suggestions found in the other threads worked.Veetle has been installed using the install.sh script and there is no unistall option
Just discovered one more thing with my installation. Builtin iSight doesn't work out of the box on Macbook Pro 5.5 as it says on the wiki.Device is not found in either Cheese or Skype.
I've been having problems in getting my microphone input to work. Frustratingly, it works sometimes and doesn't work at other times, and I have yet to discover what causes the difference. I've been testing it with the Skype Sound Test Service.
My laptop, like most others, has a built-in microphone as well as a microphone jack (which I'm using). In kmix, there are sliders for:
What do all of these do, and how do they relate to the two microphone sources? Can I use them to select input from one source while silencing the other? Where can I read about this?
I'm running Kubuntu Koala, so I asked this question over in the Kubuntu forum, but no one there has responded. That was probably not the best place to try (for this issue, at least).
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've just upgraded my web/tv setup from 9.10 to lucid and everything seems to be working apart from my infra red remote control.The remote was working fine in 9.10 and was used to control mythtv-frontend however after the upgrade the remote appears to be controlling ubuntu natively, i.e. right left up and down control what is selected on the desktop where as previously the remote was set to only work within mythtv. Whilst native support for my remote control is muchly appreciated(if that is what this is) where can I configure the controls so that it is usable again?
I 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.
I have an Intel GMA 500 and driver support is iffy plus when I installed ubuntu netbook remix, it only runs in desktop mode not netbook mode. Plus I cant control the brightness with the MSI hotkeys.
I got a new Sony F series laptop and struggled thru getting the video card to work, the wireless card to work, and the volume to work on 9.10. The brightness controls have stumped me though. The screen is on full bright and the brightness controls (FN+F5 & FN+F6) make the applet display change but the actual screen brightness does not change. I have also tried the brightness applet in the panel and that also has no effect on actual screen brightness.
I am running Karmic (9.10) on my macbook air (2,1) and although many things work fine (I wrote about it here:[URL]) one of the last things that doesn't work is setting the screen brightness. The FN-F11/F12 combo does bring up the brightness adjustment notification window (top right) and I can change the setting, but it has no effect UNTILL I reboot or suspend to RAM and reboot.
A related issue is that the brightness doesn't automatically adjust to the surrounding brightness.
I originally installed Maverick on my Macbook 5.1 using rEFIt to dual boot. For some reason, after installing Compiz my screen brightness functionality stopped working. It was permanently 100%. I thought that upgrading to Natty might work, but no luck. So far I've tried changing the brightness manually in terminal and in power-management, editing the grub file and also reinstalling compiz, all to no avail. Trying to alter brightness using the fn keys displays the brightness panel in the top right, and it decreases in value as it should, but the screen stays bright. The brightness settings work fine when I boot to Mac.
I have an issue with Debian 7.8 (wheezy) on my laptop. I've had to reinstall Debian on my laptop and since then I've had issues getting brightness controls to work properly.
It's a Core i3 370M processor with Ironlake graphics, I've had this issue before with Ubuntu and I sought [URL] ..... I've tried the steps that worked for Ubuntu (thinking they'd be the same as they're both Debian based) and it hasn't worked.
What should I try to get it to work? Since I have updated my grub config (as per the Ubuntu fix), brightness doesn't work at all and my screen now tiles ever so slightly when moving the cursor from side to side. I'll revert those changes if need be or if this issue cannot be resolved.
I've tried to install the Intel graphics drivers from 01.org, however I get an issue with libglib dependencies not being satisfied ( libglib2.0-0(>=2.37.3) ) that how to resolve.
I have F15 fresh install on Samsung Q45. The brightness function key is recognized but doesn't really increase or decrease brightness. It is set to maximum.There was a workaround in F14 for same problem.
I just finished installing Slackware64 13.37 on my Sony Vaio PCG-7153L, and I'm having issues controlling the LCD brightness of the laptop. It still has the stock Slack kernel 2.6.37.6 SMP The brightness controls worked on Fedora 12-14, as well as the Ubuntu 10.04 live disc. I checked /proc/acpi/, but there's nothing in there to control brightness. I reloaded the sony_laptop kernel module, and from dmesg I get:
Code:
sony-laptop: brightness ignored, must be controlled by ACPI video driver From the Ubuntu bug [URL] and the Red Hat bug [URL] it looks like they've already dealt with this problem. However, as I said earlier, my laptop worked fine with Fedora 12-14.I know Slackware does minimal fiddling with the kernel, so I'm thinking this might be an upstream kernel bug...
I have a Macbook 2,1 since 2007. Last week my hard drive just died, so I decided to replace it with a new one, no problems with that. The problem came when I had to install an operative system, because my DVD drive has been broken for a year and a half now. I know we can easily install MacOSX from an external usb drive, but I don't have a big enough pendrive at the moment. So I went for Ubuntu. I have managed to get an Ubuntu 10.10 live usb stick working like charm, if anyone is interested. I just downloaded the latest i386 iso and followed this advice by pxwpxw for the 32bit EFI.
The only thing I had to change in the boot.cfg was the name of the iso and -very important- changed initrd.gz for initrd.lz. The live usb works great. But I decided to do an installation on the hard drive. I installed it using the whole hard drive and didn't get any errors. But when I boot the macbook it doesn't detect anything. I guess I need an EFI bootloader or something to make it work. I've tried to follow this guide but it seems to be intended for someone who already has MacOSX and the Ubuntu installation working. I just want to install a bootloader or whatever I need from the "outside" (from the live usb I'm using). I tried to just throw reFit into the main hard drive's root folder but it doesn't work. I think that maybe creating an HFS+ partition and installing reFit in it may work, but I don't think I can create that kind of partition from the Ubuntu usb and I also need a working MacOSX to run the enable.sh. I've also read of elilo but I've seen that it hasn't been updated for 3 years
I am having a weird issue where my brightness keys on my macbook v4.1 work, but for some reason the brightness notifications have stopped working. I can clearly press the buttons to reduce and increase the brightness, but no notifications. Network manger, sound, firefox, amarok notifications work, but not brightness. It did popup, but I am note sure when or what update broke the notifications.
I'm running 2.6.35 on a macbook Air. Since Hal is being deprecated I got rid of it but now I cannot control brightness with the keyboard.Looking at the code on gnome-power-manager, if it doesn't find hal it defaults to xrandr, but I couldn't find a way of controlling brightness with xrandr. Also, I don't see any keybindings on XF86MonBrightness{Down,UP} with gnome-keybindings-properties.I'm loading mactel's nvidia_bl module which creates /sys/class/backlight/nvidia_backlight and from there I can just adjust brightness by editing the corresponding file.
