Windows 8.1 - Brightness control issues!!

Microsoft - Nowhere in all the communications you've posted here have you even remotely taken responsibility for this bug! The first time we go to adjust the screen brightness after updating to 8.1 - the screen goes down to it's minimum brightness setting
and will not adjust, no matter how we try to adjust it. My P500 Lenovo had the same issue. I talked with Lenovo support and they knew the driver that was included in your 8.1 update was the problem. We tried installing an 8.0 driver & a driver
from the Intel site to no avail. Lenovo support finally installed a basic Microsoft driver which solved the issue! My question - at this point - is, if it's obviously a problem related to the 8.1 update - when can we expect a fix? When 8.2 comes up - do we
dare assume that the driver in it will be solving the problem - or will it reintroduce it? As customers who purchase your product - we expect better
communication regarding issues that crop up. We don't expect perfection - just
integrity!

I shall suggest you to uninstall and reinstall graphic driver.
Intel has already come out with graphic driver designed for Windows 8.1 32bit and Windows 8.1 64bit.It is available in Lenovo's website and it is applicable for P500.There is absolutely no need to install the graphic card driver made for windows 8
when the driver for windows 8.1 is available in manufacturer's site.

Brightness control issues after update

after updating nvidia driver even with brightness control enabled in the xorg.conf file I cannot adjust brightness. and using the driver control panel I cannot adjust brightness, hue, or saturation under the Xserver Xvideo correction tab.

The cross-posting was a mistake on my part. I thought the post didn't submit rather than being moved.
I have a 680 gtx mobile card in an system 76 gazp6.
The issues I found were irreverent or were resolved by enabling brightness control in the xorg file
This happen after an update to the driver and the xorg file becoming corrupted.
it was rebuild with nvidia built in tool.

U460 Brightness Control Issues (Only goes from Brightest to Darkest)

My Ideapad U460 is having problems with the brightness level. It will only switch from the Brightest to Darkest brightness level...meaning it's either too bright or too dim. I've tried switching my power options too but everytime i try to adjust the brightness either by just clicking the "Fn" button to adjust the brightness or changing it on the Control Panel's Brightnes Options by moving the cursor down the brighness scale (it STILL only goes from the lowest to highest in brightness).
Please help! This is quite frustrating since it goes from being WAY TOO BRIGHT to WAY TOO DARK. Also, I recently had my screen changed because it was malfunctioning. Everything is fine in terms of my memory and just the laptop itself but the brightness issues are becoming unbearable. THANKS IN ADVANCE FOR THE HELP

Thanks for the help! Sorry, I've been out of town so I haven't been able to respond. However, I have some questions.
How do I update the Graphics driver and Bios of my system? Are both updates through the link you provide?
Also, how do I know which Graphics Drive to download (I attached the different drivers I see below)? I have Windows 7 on my Ideapad U460. And where do I update the Bios?

Jabber for Windows 9.2 deskphone control issue

Hi experts,
I'm having a problem with the newly installed Jabber for Windows 9.2.0. When I click on the bottom right "control phone" and select my Cisco 7941 it fails. I tried restarting the Cisco CTIManager service with no luck.
Deployment:
IM&Presence: cloud (Webex service)
CUCM version: 8.6(2a)
LDAP integration: full (with authentication)
Deskphone control was working prior the upgrade of Jabber for Windows. Everything else remained the same version.
Using Jabber softphone as a client still works fine.
CUCM ENd User is correctly configured.
Wireshark trace of my Jabber for Windows 9.2 client communicating with CUCM when attempting to control my deskphone shows the following:
Username: filippo.zangheri
Password: checked three times (it is correct because Jabber softphone works fine).
Any hint?
Thanks.
Filippo

Davide,
I know i am kind of late to the party on this one but i have fixed my issue and wanted to give you the information to see if this will work for you. If this is even still an issue?
I too had the same issue and just like you i confirmed everything was correct however I discovered something when I was looking into my End User profile on the CUCM. I had originally swapped my 7971 phone with a new 8945 phone and I had both phones associated with my line for a while before I removed the old 7971.
My End User profile still had both phones associated with my number even though the 7971 phone had been removed from my line. This was not allowing the CTI to connect to my 8945 phone or allow my jabber client to "Control Phone" properly because it couldn't figure out which phone to control. I went into the CUCM and physically deleted the 7971 phone from the system which released the associated phone in my End User profile. Once I did that, I "Control Phone" in my Jabber client and voila it worked like a charm!
To make sure I didn't have any Jabber client issues after doing this i signed out of my Jabber client and deleted the local system profile for the Jabber client and then signed back into Jabber and let it recreate the profile. Once that was done i have not had any issues with my Jabber client controlling my phone and all functions work perfectly.
Hope this helps...

[Solved] Screen brightness control issue

I just purchased a Lenovo T410s. I have set it up to only use Nvidia and only give visibility to the Nvidia GPU. The problem I have is once X starts I can no longer change the screen brightness with the function keys. I'm using KDE and it registers that I'm trying to change the brightness but the screen never changes. If switch to run level 3 I can use the function keys to change the brightness without an issue. I'm confused at what is causing the issue. I'm not sure what information you need to help me, but I will give you what you need if you tell me.
EDIT: I discovered on the Nvidia forums that the backlight function was disabled in the drivers for this model. Apparently when in use it causes squealing sounds.

I did some more testing and here is what I found out. I switched my laptop to use integrated GPU only, so that means Arch sees my GPU as the Intel HD. Now I can boot X and control my brightness with the functions keys. Has anyone else run into the problem with Nvidia drivers and the Quatro NVS 3100m GPU?

HP Pavilion 17" AMDA10 F2 F3 brightness control not working after win10 install

After installing windows 10 my brightness controls F2,F3 stopped working. I found this out because after the install my laptops display was super bright and i tried to tone it down using the function keys.I did download the AMD catalyst control and can turn it down there, but my function keys for it are not working, is there a planned update to fix this issue? Thanks

Hi there , Thank you for visiting the HP Support Forums and Welcome! This is a great site to get answers and ask questions. Have you tried in the Device Manager to update the driver that is currently installed? In the device manager try selecting find new hardware. At this time, I have a document to assist with Using the Function Keys. You can uninstall your keyboard driver, restart your Notebook, then reinstall the drivers. The HP Support Assistant can help you. Here is a link to the HP Support Assistant if you need it. Just download and run the application and it will help with the software and drivers on your system that need updating for Windows 10. Here is troubleshooting when drivers are not available yet. Updated Windows 10 drivers will become available on the HP Drivers and Downloads Page for your product. They will be released as they become available to HP. Have a great day!

Brightness control keys not working (f2+f3)

After upgrading to windows 10, my Brightness control keys(f2+f3) have stopped working.What shall i do?

I recommend that you download and install the latest version of the HP Support Assistant and run the Tune up application.http://ftp.hp.com/pub/softpaq/sp68001-68500/sp68201.exe It may find drivers that resolve the issue for you. Drivers and firmware that worked under Windows 7, 8 and 8.1 should also work for Windows 10. That is a nice and new feature of Windows 10. Install the Synaptics Touchpad driver software for Windows 8.1. It should work under Windows 10. Install in compatibility mode if needed.http://ftp.hp.com/pub/softpaq/sp63001-63500/sp63417.exe Verify that the installed BIOS is the current version F.19

My screen brightness control buttons don't work windows 8

my screen brightness control buttons don't work?
the light in the mute button is always on when NOT on mute?
Have set up Win8 3 TIMES but get always same bug agan
Hope someone can help

Hello smarisig. I understand you are not able to control screen brightness from the keyboard on Windows 8. By chance, did you upgrade to Windows 8 from Windows 7? I have located an online forum that contains troubleshooting on this issue: http://thedailybuggle.com/forum/unable-control-screen-brightness-windows-8-a-200.html
The person who posted the issue on this forum had upgraded from Windows 7 to Windows 8, and then this issue occurred. That is the reason I asked if this Windows 8 was upgraded. Regardless, follow the troubleshooting presented and it could resolve the issue for you. If not, let me know and I will continue to research the issue in the meantime. I'm only here to help!

Windows 8.1 update and brightness control

I have a DELL XPS L521X with Windows 8.1 (I had windows 8 some days ago) and I have had two problems:
1) I did not allow Windows to upgrade to 8.1 and it forced me to do it. It gave me 15 minutes to save progress and do it. I was watching the NBA finals on my computer and it was the only thing I had to watch the game. The installation lasted the whole second
half the game and I WAS NOT ABLE TO WATCH IT DUE TO THIS, YOU CAN IMAGINE HOW I AM FEELING ABOUT NOT USING WINDOWS EVER AGAIN... How can I prevent it from ever upgrading anything without my consent? I had already turned off updates from Control Panel\System
and Security\Windows Update but it didn't help.
2) My brightness control became broken after the 8.1 update. I had to manually pick the older Intel HD 4000 driver to have it working again or else my eyes would stop functioning after such a bright display. I had to switch to the 9.17 driver version from
September 2012. Where can I get the lastest WORKING version of the driver?
Please stop making me loose days fixing Windows issues...

Hi,
We have set the GP to disable Windows 8.1 update in Windows store, you can check it here:
How to Disable “Update to Windows 8.1 for Free” Notification in Windows 8 Store?
http://www.askvg.com/how-to-disable-update-to-windows-8-1-for-free-notification-in-windows-8-store/
For your second issue, it's not only related to Windows, but also the driver provider. Microsoft is working together with the device manufacturers and partners to deliver update package and try the best to solve the compatible issue and bring a great improvement
on user experience. But you know, it will take some time.
Thanks for your understanding.

Brightness control not working in Windows 8 x64 after sleep with Boot Camp 5.0.2

Hi,
I am using Boot Camp 5.0.2 with Windows 8 x64.
Wheen the computer has been in sleep mode, and wakes up again, the brightness control won't work as expected.
Usually the screen is to dark (darker than before, what it should be), and after some time pops up brighter as it should be.
Has onyone else seen this issue?
I mean, it seems that for brightness we use the internal control GUI of Windows 8, and not the Apple one that is used in Windows 7 and in Windows 8 for the sound control.
Macbook Pro 13" Retina, early 2013 (brand new) with 8GB RAM and 512GB SSD and 3.0GHz i7.

I have been having the issue of no brighness control when running windows through bootcamp for about 6 months now and have not found any applicable solution online.
While messing around trying to figure it out yet again I noticed that my monitor driver was signed by team viewer...
Sure enough clicking the roll driver back button resolved the issue by rolling the driver back to the Microsoft driver...
So long story short:
Right click "My Computer" click properties
Click device manager (lop left of window)
Expand Monitors section
Double Click monitor
Click driver tab
If the driver here is not signed by Microsot or Apple click the roll back button. My driver version is 6.1.7600.16385 (Driver date 6/21/2006)
Rolling this back instantly resolved my issue. I will now propagate this post to all the threads I saw regarding this issue.
I am running windows 7 x64 Ulti on a 15" rMBP.
Best of luck

Brightness Control not working after Windows 8 install...

Hi All,
I have a late year 2010 MBA core2duo with 4GB of ram, and I was running Windows 7 for a long time and recently bought a Windows 8 upgrade key. I heard the boot camp drivers were updated so I decided to load it up. I installed the new boot camp drivers on the Windows 7 side before the upgrade (had to use the command line to do the driver upgrade).
Windows 8 is all installed and the only issue I have is the brightness control doesnt work at all. I disabled the adaptive brightness as a lot of threads have been saying. Anybody have any ideas what I need to do to fix this?? It seems to be stuck on BRIGHT.

Windows 8.1 kills screen brightness control

I have a touch smart 23 computer that came with windows 8.0. An auto upgrade to 8.1 caused the screen brightness control to stop working and the screen stays on super bright. I could not get a response on how to fix so I had to re-install 8.0 which fixed the problem. I set the system to not upgrade without my approval and yet it did it again last week (about 4 or 5 months later). When I have to reinstall 8.0, I have to re-install several primary programs as there are no restore points left except back to factory settings. Question one is - has there been a fix installed on windows 8.1 that will again let me control the brightness on my screen? If not, question 2 is how did the update override my setting to not allow updates to install without my approval. I have a full day of re-installs that I don't want to have to do a third time.

Hi:
You probably have to install the W8.1 graphics driver for your specific model.
Normally when you can't control the screen brightness, that means the graphics driver isn't installed.
As for your second question, that I do not know.

[Solved]Brightness control doesn`t work anymore

Hi!
I`ve made my 3rd update of Arch since installation, and... where previous two succeeded, the third one failed. It messed up my system
The problem is, i cannot change brightness any more through my function keys (and since i`m using Openbox as my DE, i cannot change it at all ). The brightness now is so low that i can barely see what i am typing. And it is not only in my Arch, it also messed up Windows and everything else: grub, bootup screen where i can select bios properties - everything. I ran xev and now i see that FN+Right/Left are not detected anymore as brightness keys. It says:
FocusOut event, serial 32, synthetic NO, window 0x3200001,
mode NotifyGrab, detail NotifyAncestor
FocusIn event, serial 32, synthetic NO, window 0x3200001,
mode NotifyUngrab, detail NotifyAncestor

0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
However, FN + Win + Right/Left are now detected as brightness control function keys
KeyRelease event, serial 35, synthetic NO, window 0x3200001,
root 0x13c, subw 0x0, time 521221, (348,-43), root:(1219,884),
state 0x40, keycode 233 (keysym 0x1008ff02, XF86MonBrightnessUp), same_screen YES,
XLookupString gives 0 bytes:
XFilterEvent returns: False
But pressing them doesn`t work either. I thought that it was xfce4-power-manager problem, but changing to gnome-power-manager didn`t help either.During the update pacman also upgraded kernel to latest version.
Any ideas?
P.S. My notebook is Acer Aspire 7720g with Nvidia 8600M GT. I tried solutions from this topic: http://bbs.archlinux.org/viewtopic.php?id=73889 but none worked for me... The problem is that the system is completely unusable at this point, since i barely see anything on the monitor, and that sucks

I can't see what you did in Arch affecting your windows installation at all. If you try to boot into windows and increase the brightness (since most laptops store the brightness level of the laptop as it was set, on battery, at least my 2 laptops do), does the new brightness level "stick" for all things? If so, the only issue you have is to re-map the function keys properly, and to configure a script or something to increase/decrease lcd brightness. You can make a simple script that echoes a value into your /proc/acpi/video/LCD/brightness file (the file path will vary, so it may be under UVGA or so). If, however, it doesn't increase again, it may very well be a hardware issue, and not a software (since, as I said above, it's highly unlikely that an Arch update has affected Windows in any way).

Touchsmart 610 no longer has Beats, Brightness Control with Win8 Upgrade

Hello,
When upgrading to Windows 8/8.1 I lost all Beats audio functionality and brightness can no longer be adjusted (there is a brightness slider but it does nothing).
Main Issues Noticed:
-When putting the computer to sleep or shutting down the audio makes a loud "pop" noise even when speakers are muted.
-Beats is gone, can't find any drivers to restore it.
-Brightness cannot be adjusted via brightness control on Win8 nor via system graphics properties.
-610 does not have any physical brightness buttons to adjust.
I have tried restoration to previous configurations, reintalling drivers, etc and nothing has worked so far.
Any help would be greatly appreciated.
Thanks.

Hello @EvoGuy,
Welcome to the HP Forums, I hope you enjoy your experience! To help you get the most out of the HP Forums I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.
I have read your post on how your desktop computer no longer has Beats Audio or Brightness Control after upgrading to Windows 8.1, and I would be happy to assist you!
According to the available supported software for your computer, there do not appear to be any available drivers for your Windows 8.1 operating system. If you wish to utilize the features of Beats Audio and the display brightness, I suggest refreshing your system back to Windows 8.
I hope this helps!
