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...
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 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:
I am having problems with the brightness control on my sony vaio laptop, at virst when i upgraded the driver for the VGA card the whole screen went blank, I had to port a bin file from windows and write my own EDID file to get it to work (nVidia GT 230M), but I am having problems with the brightness, although ubuntu does read the input from the keys (FN+...), the brightness refuses to change, adding the brightness applet to the taskbar does not work either. I really need to be able to change my brightness because the battery usage is off the charts.
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.
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 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 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.
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'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.
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.
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.
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 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.
To use games and other intensive applications, but with the switch I completely lost control of the brightness for the monitor. Is their a way to configure that, through the terminal or external application. If not, is there an experimental 3d version of nouveau I could try. Help would be appreciated, everything else works great so far.
I bought a Asus eeepc a few days ago which I really like, with the exception of one thing - windows 7 starter. I like Windows 7, but starter is just bad. I also really like ubuntu, so I've decided to put it on my netbook. I download the netbook edition from the site, put it on a usb drive, and than tested it out - well, my screen is dim, very dim. Changing the brightness setting on the tool bar up top doesn't change anything, and using the function keys does change it, but still keeps it very dim.
I've tried restarting my computer, same thing, I've tried messing around with settings in the battery options, nothing... I really don't want to install it if its going to be this dark, I can see things, but its not very pleasant to use. I'm starting to consider that its the problem with the file I downloaded. Theres nothing wrong with my netbook, everything worked perfectly fine in Windows 7. I use the full version of ubuntu 10.04 on my other laptop which works perfectly fine, I'm not sure why this version is acting so weird on my netbook.
Every once in a while my laptop screen gets stuck on the lowest brightness setting. I go to the brightness setting, and it tells me it is on the highest setting. When I reset my settings, nothing happens. And I notice this usually happens after I have put the laptop in suspend mode.
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.
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).
i installed Slackware 13 no problem.i didn't configure my network from the installer. now when i log on and plug in the ethernet cable nothing happens. i am not sure if this is a hardware issue or a software issue. p.s. if it makes any difference the light green backlight does come on when i plug in the cable both on the computer and on the modem. i have now installed slackware 13.1 and it works great
I'm currently installing Slackware 13.1 on my old Sony VAIO. It's got a wireless card sticking out the side of it, and I just want to make sure I set it all up correctly. I got to the screen where it's asking: static IP DHCP loopback And I'm not sure which one to pick.
Researching this problem, I find very often this solution:
Code: echo -n 100 > /proc/acpi/video/VGA/LCD/brightness Unfortunately, I don't have that on my old PC: Quote: ls -F --group-directories-first /proc/acpi/ button/
If its possible to have the fan running at all times? I wanted to set my laptop fan to run even when its cool, as a preventive measure. is that possible to set it to run constantly(using ubuntu 9.04, by the way)?
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?
