10.8.4 Screen Brightness Keys No Longer Work

I ran updates this morning and I assume it updated to 10.8.4 from the app store updates tab.
After this update and booting back up the screen brightness keys no longer work. F1 and F2 keys do nothing and they worked fine before the update.
Anyone else experiencing this? If so know a way to fix it?
Thanks
Patrick

I have been having the same issue and even with updates have continued to have the problem. I was able to find a chck box under the keyboard settings that I never noticed before. When checked it only allows you to use the function keys on the top of the keyboard when pressing the fn (function) key. Simply unchecking this (not sure how it got checked in the first place) solved the issue immediately.

Reset SMC but Screen Brightness Keys still don't work

hi all.
i noticed after squinting at the screen all day yesterday that my screen brightness keys F1 and F2 on my mac pro keyboard are not working.
first thing i did was look in the UI for some kind of manual setting like for the Sound and i was not able to find one so the screen is still a bit dark for my needs.
then i /unchecked/ the "Use Function Keys as..." box in the Settings in case something was screwed up or changed there.
then i reset the SMC controller which i basically did by default (as i understand it) by shutting down the computer and unplugging it overnight during a thunderstorm.
now i am back at trying to solve this and i am wondering if i should reset the PRAM which i guess i will do but i don't want to have to bother with resetting all the settings on this if i don't have to.
any ideas on what may be going on? i have a 23" cinema display and a Mac Pro 1,1.
THANKS

Inconsistent Actions With "Dim Screen Brightness" Key (F1)

On the MacBook Pro, the F1 key is automatically mapped to dim the screen brightness. However, sometimes when I press this key, the screen shuts off (or at least goes to the lowest brightness setting) and other times it just goes down a single brightness point.
I can't figure out why it does one thing sometimes and another thing other times. Is there some logic afoot here? Or just whatever MacOS feels like on the day?
thanks,
tom

Could this be due to the present brightness of the screen or are you saying it could be at 90% brightness, then you press the F1 key, and the backlight turns off?
If it is dark in the room, the screen can be at its lowest setting, then pressing F1 will turn off the backlight.

Screen brightness keys not working

Simple as that. Any idea how I turned this off by accident?

Press and hold FN, on the bottom left portion of your keyboard, then press the brightness keys. IF this causes your brightness to change it means you have enabled the f1, f2, f3 keys as the stardard function keys.
To change it back to regular open up system preferences go to keyboard and click

Screen brightness keys not working after 5.0 update on Windows 8.

I believe the drivers for the screen aren't working since changing the brightness manually in windows isn't working either. There is also an error with the intel hd 4000 graphics, if that has anything to do with it. This problem did not occur before I downloaded the new drivers for windows 8.

Same thing is happening to me as well, just posted about it 30 seconds ago. PLEASE HELP

How to disable minimize and maximize buttons of a popup window

W510 Screen Brightness Keys Disabled

Hi,
I often hibernate my W510 and some times when I start her up again, the brightness function keys refuse to work. Other function keys seem to work ok. It's a real pain if I'm trying to conserve battery and the brightness is on full (notably it doesn't automatically switch to a lesser brightness either when this fault occurs).
Anyone else experience this?
Regards
Andy Wu

Another thing to note besides the fact that this only affects the brightness controls, is that the controls are affected regardless of whether I am plugged into AC power when I bring my laptop out of hybernation. Also, rebooting the system doesn't fix the problem. I have to physically shut off the system and power it back on to resolve the problem. I don't need to remove the battery, but the system does need to be completely turned off.
Does anyone know if the Lenovo techs are aware of this problem?

How to *disable* or change behavior of brightness keys

Hi there!
I own a HP laptop with a dual Nvidia/Intel graphic card, with propietary drivers & bumblebee installed, and everything works perfect but brightness buttons.
In fact, they work, but not as they should. When I press the brightness up button, it raises, but it does it a lot. If I press it again, the brightness sets to its maximum value when the progress bar it shows is on ~20%
This is my theory of what's going on:
I have 3 folders on `/sys/class/backlight`:
[root@Archpv3 backlight]# ls
acpi_video0 acpi_video1 intel_backlight
`acpi_video{0,1}` are, if not identical, equivalent: All the files inside them are equal. `intel_backlight` is different.
`acpi_video{0,1}/max_brightness` is 100. But, experimentally, I have ensured that the actual max_brightness of my screen is 20.
My theory is that, the thing listening on brightness buttons (and not, its not acpid), gets the maximum value from `acpi_video{0,1}/max_brightness`, and when I press a brighness button, it raises it to `acpi_video{0,1}/max_brightness`/10.
There may be three solutions to this: Change the `max_brightness` to 20 by machete, or change the step by machete too. Other solution will be to tell the thing I want it to use `intel_backlight`.
I dont' know how to do anyone of these because I still don't know what the hell is listening that events :\
So, finally, and sorry for such a big intro, does anyone knows?
Regards, and thanks in advance ^^
EDIT: I though backticks ` will make the in-line code effect, but they didn't. Sorry if they annoy you xD

Hello qimbal2,
Thanks for getting back to me. you are right , i should disable the link as soon as it is clicked. I went ahead and implemented this logic by using a property in my bean class and binding that property to the value of my link. I wrote the logic in my action method in such a way that when i click on follow for the first time, the value of the link would change to 'Following' and the link would be disabled. It works for me now.
Thanks,
Suha

Enabling / Disabling graphs and opening a new Front Panel Window

Hi,
I have a simple application of showing 12 analog signals on 12 different graphs placed vertically in aligned position. I have to develop a user interface so that if user wants to display signal no. 1, 4 and 6 out of total 12 signals, he should make selection using check boxes and click a re-draw button. It should result in opening a separate window with these three signals displayed as separate graphs aligned vertically and adjusted to fit window size. Similarly later user can change his selection of displaying signals (from same acquired data) say 1, 3, 5, 6, 8, 9, 11 & 12 and click Redraw button. It should result in opening a new Window showing all these signals as separate graphs which are aligned vertically and resized to fit the window. Now I have two major issues in this context.
1) I have been searching LabView help to locate a way to open a new window for this purpose but I failed to locate any way for it. As per my limited knowledge, it seems that we cannot have multiple "Front Panel" windows in Labview.
2) For the graph I could not locate a control to enable/disable a graph so that it appears or vanishes. Is there any way to achieve it?
I shall appreciate your valuable advice. I shifted from "Lab View Signal Express" to "Lab View" in order to achieve this user interface design but I am still not successful in finding a good solution for this application.

Mnuet

Hi Mnuet,
You can do what was said above. Here is a KB on dynamically loading VIs. It looks something like this.
Dynamically loaded VIs are loaded at the point in code while running, as opposed to being loaded when the parent VI is loaded into memory like normal subVIs. You can make a reference to them and then control the front panel appearance, their run status, etc with property nodes and invoke nodes.

RDC with Mac Laptop and Second Screen - Cannot move Mac Windows onto RDC Screen

The older version of RDC 2.1.1 works perfectly with an additional screen. With the new version 8.0.10, although you can launch and use RDC, you can, no longer, move a window over onto the second screen. So RDC works fine, but you do not have the flexibility
of using both screen while RDC is running. This is clearly a backward step from 2.1.1.

Hi,
Thank you for posting in Windows Server Forum.
There is one expected MAC behavior as on Mac only one app gets focus when you go full screen.
In addition, please share some more light with snapshot for your issue for further research.
Thanks for your understanding and support!

Odd Screen Brightness behavior

When I toggle the screen brightness keys, the status bar stops to notches short of all the way bright. When I open system prefs and slide the status knob all the way to the right, it stays at about 80%?
Weird?

Hi rahzel,
Welcome to the Lenovo Community Forums.
Regarding the Screen Brightness sliders, its not that they are not synching its just that they are not scaled right. As you have explained the PP (power plan) screen brightness slider when set at half, the corresponding PM (power management) slider is 3/4 full. I tried this with a different lenovo unit (B570) running Windows 7 and its the same thing. We have no option to change this since this is scaled by Windows 7.
The Lenovo Energy management It just gives you the option to toggle from the 3 power plans listed. Regarding the On screen indicator, I may suggest that you try to uninstall and reinstall the Lenovo Energy Management program. Check to see if this addresses the Onscreen indicator problem.
Let me know if this helps.

S10-3 Screen Brightness Linux work around

I am running Mint 9 and Ubuntu 10.04 on my S10-3. Very happy with the platform overall, but as many have found their screen brightness keys do not work. My web research indicates that the latest kernels will have a fix, but that probably won't be commonly available until the end of 2010. In the mean time I have implemented the following to get easy control over the brightness. It's not perfect but it gets the job done. Create three launchers on the desktop with one each of the following commands. Select the screen brightness icon and title each launcher as Low, Med , High Low> sudo setpci -s 00:02.0 f4.b=35 Med> sudo setpci -s 00:02.0 f4.b=55 High> sudo setpci -s 00:02.0 f4.b=75 credit to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/538256 http://lgallardo.com/en/2010/08/31/control-del-brillo-de-lenovo-s10-3-video-gma-3150-on-linux/

Maybe this topic is outdated, but probably this info will be useful for S10 linux users: official ubuntu kernel 2.26.35-25+ works good. This means new Ubuntu, Mint 10 and similar forks works good with brightness adjustment with no additional tools or tweaks.

[XP on late 2008 Unibody] No option to auto-adjust screen brightness

Why does there seem to be no option to automatically adjust the screen brightness in the Boot Camp control panel on Windows XP SP3? I remember having run Windows Vista on the same machine and automatic screen brightness would work in Vista.

Hi,
Open windows Control Panel and open Power Options. Click on Change plan settings next to your selected power plan and in the following window, click on Change advanced power settings. In the Advanced settings window, expand 'Enable adaptive brightness' and set it to Off. Click Apply and Ok to save the setting, the restart the PC.
If you can't locate the option in the Advanced power options menu, you can always disable the service responsible for this as shown in the video below.

Bootcamp win7 secondary screen brightness

Hi,
I have a macBook pro with bootcamp (win7-64) and a secondary screen connected trough the hdmi. The brightness of the secondary screen changes constantly, seems related with the content of the same screen. For example, if i have opened a photo, wich is mainly dark, and I maximize a program like Word, which is mainly white, the brightness changes a lot. this problem doesn't happen in laptop screen.
The win7 brightness control seems to affect the laptop screen only.
How to disable this annoying secondary screen brightness auto adjust?
Thanks
