I 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'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 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 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.
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 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.

View 8 Replies View RelatedWhen increasing or decreasing the screen brightness, Minecraft crashes and to an extent freezes my computer UI. What I mean by to an extent is that I can move the cursor around, but I can't click on anything. I can also run keyboard shortcuts and type, which is how I restore my system by terminating all java processes with pkill.
What causes minecraft to crash and how can I solve it?

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.
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 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'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.
View 3 Replies View RelatedI 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 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'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 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 4 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.

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'm having trouble locating a way to adjust the screen brightness on fc10... It is only possible to use the monitor's control for now.Yeah my monitor make an annoying whining noise unless you turn it on 100% brightness, but that hurts my eyes.It is so crazy that they didn't put a brightness control in! ( or rather they destroyed working ones of year past, Why? )
View 4 Replies View RelatedMy issue is like this: I have a laptop (dell vostro 1400, NVidia 8400M video card) running Fedora 12 up to date. My desktop is KDE 4. I usually run the laptop connected to the power outlet, so my power profile is set to "performance". This power profile sets the screen brightness to the maximum. However, when I'm in the dark, I want to lower the screen brightness. The shortcut keys work, and the screen brightness is lowered. However, for some reason, after about 30 seconds it resets itself to the highest brightness setting. No matter how I set the brightness, it will always reset itself. Any ideas what can i do to correct this?
View 3 Replies View RelatedRunning F14 on Dell Studio 14 with LCD screen and US keyboard selected. After initial power on the keyboard selection of "Windows Key" + F4 will dim the screen and the "Windows Key" + F5 will brighten the screen. When being used, either combination will also show a meter on the screen to display the adjustment of the brightness. When the lid is closed the computer is set to suspend by default. After the computer is brought back from suspend the keyboard short cuts no longer control the brightness and the meter does not appear on the screen. I have not found any other way to control the brightness and I have to restart to get the keyboard short cuts to work again.
