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.
View 3 RepliesI'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)
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.
View 9 Replies View RelatedMy 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 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.

View 8 Replies View RelatedI 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.
View 9 Replies View RelatedI'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.
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 RelatedI 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 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 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.
View 9 Replies View RelatedI usually can solve problems with ubuntu with a quick search, but I can't figure this one out or anyone else who has this problem! I recently installed Xubuntu on an old eMac PPC using the mini CD. Everything went pretty smoothly, and the distro runs excellently except for the fonts, Abiword, Open office, and much of the notification system refuses to display almost any font. I've tried different window managers (XFCE, IceWM, Openbox, Fluxbox), but all have the same problem. I've tried reinstalling and have the same problem.

View 12 Replies View RelatedI 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.
View 4 Replies View RelatedI 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'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.
View 4 Replies View RelatedI 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.
View 9 Replies View RelatedI 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.
View 1 Replies View RelatedI 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 looked through the wiki and for some reason I cannot get my brightness controls to work.
View 8 Replies View RelatedI'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.

I have a new netbook, a Lenovo Z360 and everything except one thing works "out-of-the-box". The one thing is the brightness control. I think it's the same bug like in https://bugs.launchpad.net/ubuntu/+s...ux/+bug/538256 But I don't get anything in dmesg, it's just not working. setpci -s 00:02.0 F4.B=?? don't work, too. nomodeset acpi_backlight=vendor don't work, too. I'm using Fedora 14 with KDE, 2.6.35.11-83.fc14.i686 and the intel drivers. Maybe somebody knows a workaround, usually brightness control works very well in the newer distributions. I had like 4 notebooks all with Fedora installed and brightness works, especially with the open source intel drivers I didn't expect any difficulties.
View 10 Replies View RelatedI have searched online with no success. The brightness control is working fine on my laptop. Problem is that the bars don't get rendered on screen. Instead I get like a static white line on screen everytime I press the brightness control. On boot however, I can see the correct bars. It is once I start my xsession, the bars do not show up. Here are my specs:
Slackware 13
Xorg Radeon driver
kernel 2.6.29.8
I bought a new computer, pretty awesome machine, AMD FX6300 with a Radeon 260X graphics. Along I bought a new Led monitor AOC with DDC/CI capability.
It is my understanding that with the DDC/CI, monitors can have their brightness controlled just like laptop screens do, but better software controlled.
This is something I have done before with nvidia graphics, the open drive had the control and the proprietary only needed a small config setting. This was done however in a dekstop iMac, the screen also LED and HDMI.
So I just freshly installed debian jessie in this setup, it seems the open source driver does a pretty good job, but still missing the brightness control and audio through HDMI doesn't work either.
Screen brightness on aluminium 24 inch Intel iMac
I was just about to re-install Ubuntu to dual boot with OS X on my 24 inch aluminium Intel iMac. Then I remembered the reason I got rid of Ubuntu the last time... screen brightness.
It is a known fault of these machines - the default brightness is set far too high. Sometimes it hurts the eyes. There is an application I have to use with OS X called 'shades'.
If I instal Ubuntu in VirtualBox I can still use 'shades', but when I run it natively as a dual-boot os, I do not have access to the 'shades' app so the screen is far too bright to use for any reasonable length of time.
Is there a workaround for this, without having to do something on every log-in?
(I am using the 64 bit AMD version of Ubuntu.)
I've just installed the Nvidia drivers on my Debian, however, after i do it, the laptop brightness control doesn't work anymore... When i press the keys, i see the brightness bar, however, the brightness stays at maximum. I've used the following commands to install the drivers.
apt-get update
apt-get install nvidia-kernel-source
m-a a-i nvidia-kernel-source
apt-get install nvidia-glx

I don't know how this happened, but my keyboard copy and paste functions have stopped working. Oddly enough, I discovered that I can only copy and paste by using the third mouse button. Pressing down on the scroll wheel after highlighting text copies the text, pressing it again pastes it Ican still use the Edit-copy and Edit-paste menu functions.
I'm sure it has something to do with all the tinkering I have been doing with my desktop. I have been experimenting with CompizConfig and Cairo dock, changing my themes and things of this nature.
