Application brightness control

Hi everyone,
main problem is that in Trine2 game, brightness control does nothing to the screen. So with default brightness, that's set in game, whole screen is very dark.
It's desktop computer with proprietary nvidia driver (graphic card is GTX 660). System is fully updated, so versions of all my packages are latest available. Additionally I've put option in xorg.conf that's documented in wiki, but it doesn't help. Maybe to mention that brightness control in nvidia-settings GUI is working.
Can someone point me to direction where to look for solution? Or is there some command/app that could set brihtness/gama for particular application?

try this in your shell terminal
for i in /sys/class/backlight/*; do cat $i/max_brightness > $i/brightness; done

No screen brightness control on an envy 17

I had some maleware that was removed and it broke the Catalyst Control Center, I only has the Intel 300 HD to view the screen from.
I used the 14-4-mobility-win7-win8-win8.1-64-dd-ccc-whql from 3D GuRu
and,
win64_152822 intel hd 3000 from the intel site.
I have the popup omn the screen from the keyboard shortcut, but nothing haoppens. its on full brightness.
Left click the battery icon in the tray and there is a place for 'Adjust Screen Brightness'. It takes me to a page 'Select A Power Plan' where it SHOULD be but doesn't show up. If I select 'Change Plan Settings' it is there but has no effect. its all still full bright.
It was working fine until the malware.
Did sfc /scannow, nothing to report.
Any ideas on this?

Hi @fjward ,
Thank you for visiting the HP Support Forums and Welcome. I have looked into your issue HP ENVY 17-3090nr 3D Edition Notebook PC and issues with brightness control and the Catalyst Control Center. I would uninstall any graphic drivers that are listed and CCC software, restart the computer, then reinstall only the AMD. It will include the Amd Graphics Driver and Catalyst Control Center restart the computer.
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.
You can do a system restore. System restore will help if something automatically updated and did not go well on the Notebook.
When performing a System restore please note remove any and all USB devices. Disconnect all non-essential devices as they can cause issues.
Please let me know how this goes.

Using F1, F2 as brightness control

I need to enable the "Use all F1, F2 as standard function Keys" option in system preference because I run an Application that requires F6 for a function.
However I miss using F1 and F2 as brightness controls so I set those as shortcuts in the shortcuts page.
Whever I push those buttons, they just give me a screen flash as if they are not assinged, please help!
I know I can always use Cmd+F1/F2 to enable the special function but it would be useful to be able to assign the shortcut myself.

Update: I went to the Apple Store to find out the current gen rMBP does not have this option in it's System Preference pane. Not sure if thats the reason the shortcut is not available. I'm using late 2012 iMac on the current 10.9.2 release. The quck fix is to install the 3rd party "FunctionFlip" pref addon.

Hey Admin(Karl) Still have brightness control problem w/dual ACDs on G5

Can someone on the administrator or tech 3 or 4 guru level from Apple Please tell me what I need to do to access the brightness controls of my two previous generation "clear with/ white frame" apple 23" cinema displays ? I posted here two weeks ago - had no responses.
Went to AppleCare via phone for an hour - Indian person trying to help said it is available in the monitors prefs tabs/and monitor pull down menu on the menu bar next to the time ( nothing but resolution/arrangement/color profile there ).
I have since re-installed 10.4 from the original disks AND upgraded to 10.4.3 - Hoping that something would change. Nothing did.
Nothing shows up on screen when pushing the brightness buttonon either monitor, OR when I go to the monitors control panel - no brightness slider or tab on top.
It is driving me crazy to have to review my work ( digital photography ) on my old G4 system to be able to judge the proper density of the images.
I can profile the pair with a Spyder2 calibrater, and load the profiles fine, but again brightness is the issue, not the color. One of the displays is about 30% brighter than the other, and there in lies my problem.
Since the same difference in the screens is the same across various applications ( Final Cut Pro / Adobe PS / DVD player ), can I assume that this is a system issue software issue ?
Am I the only one having this problem ? Or is there just a glitch that no one has managed to tackle and fix even this far into Tiger ?
Please someone reply and save my sanity !

NEW Powermac G5 2.3 w/ dual port stock video card Mac OS X (10.4)

Hi Mel,
Sorry to hear that you are having problems.
I feel I have to point out that most of the 3 or 4 level Gurus don't actually work for Mac. We tend to obtain our knowledge from our own experiences plus sharing other peoples' experiences in this forum.
The reason I haven't responded to your issue myself is because I have no first hand experience of your problem, and I haven't been able to find anybody else who has had this problem and has been able to fix it. I'm always reluctant to respond unless I feel I have some information that will really help (or, at least, not possibly make things worse).
Anecdotally, this issue appears to have surfaced with the release of Tiger, so it may well be a software issue.
I don't know how old your G5 is - will it function with Panther? If that is the case, then installing Panther on another drive or partition (i.e. keep Tiger for now), and then booting up with Panther may give you an interim solution while the issue (hopefully) gets resolved in Tiger.
The fact that the brightness options are not available probably means that the drivers bundled with the Tiger installation for the graphics card that is in your G5 do not support the displays you are using properly. I believe that the stock video card you are using is an ATI card (you might want to check this via system profiler). At this stage, it would certainly be worth your while to contact ATI support and see whether they have drivers available that will assist you. This link may help get you started:
http://www.ati.com/products/mac.html
I acknowledge that I haven't really given you a solution, and I apologize for that. Hopefully, what I have given you will give your quest some direction.
Please let us know how you fared. All the best.
Cheers!

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.

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

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.

My screen gets dim and the brightness control buttons don't work

My screen is frequently dim. The brightness control buttons display that they are working, but the brightness doesn't actually change. Any ideas why and what I can do?

Thanks for the suggestion. Actually, I had tried that but still had to go into preferences any time I wanted it brighter. After I posted, I found a thread using some different keywords and found that people were having the same problem with OS versions up to 10.7.2 but solved it with the latest update (10.7.3). I just installed it and now seem to be able to adjust the brightness with my keyboard no problem. I appreciate your reply anyway!

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!

Satellite C650-I5011 - Brightness control is not working

It remains at maximum.

Hello,
The backlight detection depends from acpi options selection on your kernel. Which kernel version do you use ?
$ uname -a
(Use at least a 2.6.36 kernel since a lot of improvement for recent Toshiba laptop have been done during summer 2010)
This done, ACPI options beeing compiled into kernel or loaded as module, this line should appear in your /var/log/Xorg.0.log :
"found backlight control interface /sys/class/backlight/acpi_video0"
Having a C650-15Z, my brightness control works well.
regards,
alex

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

Problems in starting up Application Server Control from SOA Suite

I have an issue starting up the Application Server Control page from the SOA Suite (10.1.3.1.0) welcome page. I can open all other control pages by entering the oc4jadmin/<password> where <password> is the password specified at the time of installing (Standard Install) the SOA suite.
Application Server Control accepts the oc4jadmin/<password>, but shows another page to "Supply Administration Credentials". The following error message is shown on the page.
+++++++++
This OC4J is configured to make JMX connections via RMIS and fall back to RMI if the RMIS port is not configured. The RMIS connection on the OC4J instance home on Application Server shara.SHARA_HP is configured but a connection could not be established. The JMX protocol is specified by the oracle.oc4j.jmx.internal.connection.protocol property in opmn.xml
You are logged in as oc4jadmin.
Enter the credentials for a cluster-wide user in the oc4j-administrators group. These credentials are needed by Application Server Control to make remote connections.
* User Name
* Password
[Store Credentials} button
++++++++
Has any one encountered this? Any clues where to look for things? Initially I had the problem with all the controls due to my computer name as it has an underscore ie., SHARA_HP. I had to use localhost to overcome this ie., http://localhost:8888/em
Any help/clue would be appreciated.
Thanks
Maha

At install time there is a question that asked if you would like to configure adminstration now. (Something like that). By default this is not checked. If you did not check it you cannot access enterprise manager.
The is probably a way to configure it, but it might be faster reinstalling.
There is a simple way to de install by going to the ORACLE_HOME/bin and run the deinstall script.

IMac G5 (iSight) with 10.4.11: Screen always dimmed. Starts at full bright and a second later dimms and stays like that forever. Brightness controls work normally under this circunstance. Please help !!!

iMac G5 (iSight) with 10.4.11: Screen always dimmed. Starts at full bright and a second later dimms and stays like that forever. Brightness controls work normally under this circunstance. Please help !!!
Please don't tell me to adjust anything on the preferences, since I have tried all. I think it may be anoter kind of problem, maybe hardware related or anything.
I ran the Hardware repair DVD and everything was ok, but when the imac restarted the screen was very lit again, but when it went sleep, when it went awake again the screen got dimmed again. Because of that I think that the problem could be software related, but who knows. Excuse my english.

I can't see another possible answer - the longer your machine is up, the more the power supply is stressed, it protects itself by dimming the screen to lower the draw on it.
