OpenSUSE Hardware :: Brightness Controls Didn't Work ?
Jul 21, 2011
Recently I tried putting Kubuntu Natty Narwhal on yet again and to my surprise it mostly worked. The only major thing wrong with it was my brightness controls didn't work (I have a VPCCW21FX laptop) at first this was an anoyance being blinded by my screen but I soon realized that it was killing my battery life. So having tried to seek help in getting it to work I tried out OpenSUSE. They worked! but as soon as I updated the kernal they no longer worked. No Problem. I reinstalled and told it to never apply that update. Then I installed the official nvidia drivers via repository on the opensuse wiki. they installed and worked but my brightness controls were once again broken.
I have an Acer 4810T laptop with Intel graphics. I run openSUSE 11.3, and am about to upgrade to 11.4. But both systems still have a very bad bug with screen brightness. The Fn+Arrow keys do change screen brightness, but after using them the system is rendered extremely sluggish and unresponsive. This sluggishness is most pronounced with a very important Wine app I need to use. The only way to fix the sluggishness is to reboot. With 11.4, the problem is worse because the system boots and automatically partially dims the screen, thus making it even more necessary to change the brightness. Neither Gnome nor KDE are able to change the brightness via their power managers. This means that I can't dim my screen automatically upon disconnecting the A/C power.
I have read many experiences from Ubuntu and openSUSE users, who all have the same problem. I have tried both intellegacy and the new intel drivers, and they both have the problem. I have read that some users have improved the situation by upgrading or downgrading the BIOS. Others have been experimenting with kernel patches:
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 took the courage yesterday to install ubuntu 9.10. Internet was working absolutely fine (wireless), but brightness controls were not working (they still don't). So I went to this page https://wiki.ubuntu.co/Hotkeys/Troubleshooting, and ran following command(s) killall gnome-settings-daemon gnome-power-manager Now since then I cant get the internet working, and cant see the wifi connection on task bar. I have restarted the laptop but no avail.
PS: any help on how I can reduce the brightness of monitor. I am using SONY VIAO VGN FZ38M, with Nvidia 8400M GT. I have tried several threads and tried all sorts of things, like xbacklight, or somthing to do with sudo .VGA/LCD/brightness.etc.
I have a fairly new Samsung 2233RZ 120hz lcd hooked up to a GeForce 8800gt...
When i click on the Brightness and Contrast controls on the monitor it gives me "Not available"...
Does the linux nvidia drivers disable my monitor functions? is my monitor improperly configured? do i need to take some steps in setting up my monitor? there are some tiny white scanlines going through the display horizontally if i look real close...minimimalist ubuntu 10.04/XFCE4 same happend on ubuntu 10.04 gnome... with or without the geforce drivers.
I recently purchased an HP Pavilion dv7t 6163us and I installed ubuntu 11.04 on there. Everything works fine except the fn + f2 and fn +f3 which decreases and increases the brightness respectively. It's using the i7-2630qm sandy bridge processor and intel HD graphics 3000.
I can't get any of the video equalizer controls to work. Hue, brightness etc. If I run mplayer the brightness works but not the hue. Xine does better. Brightness, contrast and saturation work but not hue. I installed using the instructions in the multi-media post.
I just upgraded my 11.4 firefox and flash to get rid of an apparent flash problem. Before the packman online upgrade, the event pulldown on yahoo finance didn't work. It behaves the same after the upgrade. I noticed on this site, I couldn't click the cursor into the simple search window. So from openSuse, firefox is third party, adobe is fourth party and yahoo is fifth party. Who owns this problem? The rest of my system is KDE 4.6.0 on HW 686 - 32 bit.
i installed suse (KDE) on my old notebook and now I'm trying to get the wlan to connect to our router and can't figure out how to get it to work. My card seems to work, the network manager even finds the router, but i just cant get a connection. I followed the steps of the "Getting Your Wireless to Work" thread and these are the results:
[Code]....
- i messed around a bit with the network settings and might have cluelessly broken something (or broken it more)
- i tried a usb-wlan-card as an alternative, which didn't work either, but could possibly have messed things up even more.
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
I am looking for image batch processing (mainly resizing) apps. As I have problems with Nautilus Image Resize in the other thread, are there any other software that is fairly easy to use to batch resize images? Preferably from a one-click install that works. I tried Phatch, but that didn't work for me.
I can't get flash controls to work. If the video auto-plays, it starts just fine, if not, I'm out of luck. I've tried reinstalling flash through the software center. Even if it autoplays, I can't control volume or pause or anything. I'm at the mercy of whatever is already there.

It has never worked. About to pull my hair out and/or reinstall Ubuntu Completely since no one else seems to have to problem.
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.
It 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.
I recently noticed some of my one-liners with && and || didn't work as I expected so I googled for "bash && || pitfalls" and found this page [URL] It's probably my fault, but I still don't understand why it wouldn't work as I want it..... I don't even have the code anymore that wasn't working properly because I rewrote it using if ; then ; command ; fi
Just installed CentOS 5.4, had no problems until the first time it tried to login, where the keyboard didn't work. There are bugs logged on both the CentOS site, and the Red Hat site, but nobody seems to have a definitive solution (other than buy a USB keyboard). Bearing in mind that the machine in question is not hooked up to a network (i.e. no internet updates), is there a way to resolve this issue?
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 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 installed Xubuntu 11.04 on a HP Probook 4510S and the FN Keys of brightness only works when I on the login screen (gdm). Until I enter to my desktop the FN Keys stop Working. This is a XFCE Issue? I have another Laptop, a IBM THinkpad X40, with the same Xubuntu 11.04 and the FN Keys works perfect! 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.

My laptop is an HP Pavilion dv6 3078-tx. It is was a great laptop when it was running windows 7 but when I tried installing Ubuntu, I slowly began to hate it more and more. The issue is with the ATI and Intel switchable graphics card. Ubuntu installs fine and things seem to be great but I cant use the better graphics effects in ubuntu. I installed the driver that ubuntu provides for ATI and it didnt work and ubuntu booted into a terminal etc.. and I had to put it back to the way it was before. After sometime researching on the internet I know the problem is with the swtichable graphics.
Unfortunatley there is no option to turn off switchable graphic in my bios and hp arent much of a help. I dont know what to do now ? Is there any way to get switchable graphics to w ork with linux, is there way to get version of the bios that lets me disable it ? any variations of ubuntu or linux that it works with. I would prefer to use the ATI if i have to disable one or the other cause Im usually running on ac power anyways.

I have Lubuntu 10.10 on and old old IBM Think T22 with an Asus wl-107g WLAN PCMCIA card installed.. When i first installed the distribution it didn't work. Then i rebooted a couple of times and then it worked no bother, but now it doesn't work again..
The error is basically that it doesn't seem to recognize it anymore.. it doesn't recognise any network hardware other that the built in ethernet card (which for some reason got the name eth2, suggesting that there is an eth0 and eth1 but ifconfig doesn't show them)
