Slackware :: Brightness Control Screen Bars Do Not Show Up

Feb 18, 2010

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

Slackware :: Cannot Control Brightness Settings On Vaio - 13.37

May 11, 2011

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...

Debian Hardware :: Control Screen Brightness With DDC / CI Capable Monitor

Jul 5, 2014

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.

Slackware :: Ctrl+up|down Don't Change Screen Brightness Any More

Jul 16, 2010

i had slackware 13.0 on my dell vostro 1320 and it was all good, but since the upgrade to 13.1 i cannot change the screen brightness with ctrl+up and ctrl+down keys..i'm not even sure how to start with this problem. from what i understand these keys 'call' a bios function...? so that would mean that some kernel module is not being loaded?or has the desktop environment lost the key mappings and that is causing my trouble?

Slackware :: Laptop Mode Tools Screen Brightness Ability Working?

Mar 15, 2010

I'm currently trying to setup a minimal Slackware installation. Everything is well, except for screen brightness/hard disk control via laptop-mode-tools. I was wondering if anyone used it, and if they got it to work on their Slack systems, how they went about doing it.

Debian Hardware :: Getting Lenny Working On Macbook / Can't Use Brightness Keys To Change Screen Brightness?

Feb 9, 2010

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.

Ubuntu :: Using Brightness Control In 10.04?

Jun 5, 2010

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.

Debian Hardware :: 7.8 - Laptop Brightness Control

May 7, 2015

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.

Ubuntu :: Brightness Control Doesn't Work?

Mar 17, 2011

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.

Fedora Hardware :: Brightness Control With Intel Drivers?

Feb 13, 2011

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.

Ubuntu :: 9.10 - Sony F Series Laptop Brightness Control?

Feb 23, 2010

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.

Ubuntu / Apple :: Pommed And Brightness Control Not Working

Oct 10, 2010

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)

Ubuntu / Apple :: Brightness Control Not Working - Displays At 100%

Apr 1, 2011

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.

Ubuntu :: Monitor Doesn't Show Menu Bars/panels?

Jul 15, 2011

I've got a fresh install of Natty on my Dell Studio 17 laptop. The screen on the laptop doesn't work so I have it plugged into my Panasonic TV with an HDMI cable. The only problem is that the TV is not showing the outer edges of my desktop. So, I can't see the "Applications" menu, for example, or the button to click to Logout. I've messed with every setting available on the TV and nothing has helped.Can anyone provide any advice? I've started messing around with xrandHere is the output of 'xrandr':

Ubuntu / Apple :: MacBookPro5,5 Random Loss Of Brightness Control?

Jan 31, 2010

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.

Slackware :: Thinkpad T500 Fan Control - Way To Control ?

Jun 2, 2010

I have had my thinkpad for just a few short months and, it must be that we are heading into summer, but I am starting to finally run into some overheating issues especially when compiling software for awhile, i.e. kernel.

My question would be, "Is it best to let the built in thermal management take care of the issue, and I just need to know what to tweak, or to put on a script solution such as the tp-fancontrol script?

The computer takes about 5-10 minutes to overheat and the message I get in /var/log/messages is "logger: ACPI group thermal_zone / action THM1 is not defined" then it shuts down.

So, any pointers in the right direction would be appreciated.

I am running slackware-current x86_64 on a Lenovo Thinkpad T500.

CentOS 5 Hardware :: Keyboard Mapping And Brightness Control On Macbook 1,1 With Centos 5.5?

Jun 9, 2010

I tried to find the information by myself (google search, forum search, Faq, manual...) but i didn't find any clue. I installed CentOs 5.5 on a macbook model 1,1 and I have currently two issues :

The keyboard mapping is wrong (it didn't fit with the macbook keyboard, ex: the '-' is not on touch '6' for example...). Is there a way to apply macbook keyboard mapping? I didn't find how to modify the brightness of the screen. Where is this settings? It didn't appear in the video card settings that is very basic. Do I need to install a proprietary driver for my GMA on my macbook? Also, i will like to have this settings on the keyboard with the dedicated button (like for the sound that works well).
