Default Screen Brightness

I installed a fresh copy of Leopard. I have changed screen brightness and want to restore it the way it was before I changed it. I tried looking in my Preference folder, but no avail. I know it may sound a bit odd but I just want it back. I know for my sound setting, it is 11 blocks from the left.

It is not a "trouble" really. I do not know if the brightness is too high when booting the computer. I will see to see how many "blocks" it occupied. No I have not checked in Snow Leopard forum, I thought my issue is realated to the MacBook than the software? Should I consider posting it there?

What is the default screen brightness setting?

Could someone please tell me what the default screen brightness setting on a Retina Macbook Pro 15" is? Is it 50% when charging and one point less when on battery?
Thanks in advance!

That isn't really a default setting. It is arbitrary, one system might be different than another at first turn on.
Simple way to tell is wipe your hard drive and reinstall OS X. Whatever the screen brightness is at the completion of the OS X install is the default. Make a record of it.

Default screen brightness, T400

i am trying to setup default screen brightness to a specific level but all i found in the power manager tools (v 3.20) is dynamic brightness control which doesn't allow for the specific level of brightness. how should i resolve this issue? it would be nice if screenshots were provided.
thanks

You can put it wherever you feel comfortable.
I would recommend 1 step higher brightness than the least you are able to stand--this will give you a balance of battery life and comfortable viewing.

What is the default screen brightness setting and keyboard backlight brightness default setting, and how to you go back to default?

What is the default screen brightness setting and keyboard backlight default setting? I just got a new Macbook Air and fiddled a lot with it, and now just want to know how to set the brightness levels back to default. Thanks everyone!

Hey sberman,
I maxed out the screen brightness before I clicked on "restore defaults" in system preferences> energy saver (which has to do with battery, not exactly screen brightness) to see if the screen went back to a "normal" brightness level, but it didn't. I don't think it restored the brightness to default..

Default Sound Balance and Screen Brightness?

Recently my iBook G4 has been booting up with the screen brightness all the way down and the speaker balance all the way to the left. Did these settings somehow get set as the defaults? How do I change it back to normal so that I dont have to keep changing the settings every time I boot up?

There has been a bug in OSX in regards to sound balance for notebooks since 10.3.5 (IIRC). To fix it look for a free app called Balanced, that should correct the problem.
As for the screen brightness, I've never heard or seen anything like that.

How to configure screen-brightness of macbook to lowest value as default

Hi,
setup: macbook 3,1 with external 24" display. Basicly the user is only using the external screen which is defined as main screen in this 10.5 installation.
question is:
Is it possible to define the screen brightness of the macbook itself to lowest possible value ?
As the macbook screen is not used at all it would be great to disable the brightness or at least reduce it as much as possible. I can do that with the brightness-key, but that is only a session setting. not permanent.
any ideas ?
best regards

[FIXED] after upgrade ACPI can no longer change my screen brightness

EDIT: never mind, it seems to of gone away now...i have no idea what happened, it stopped working randomly then started working just as randomly.....whatever...
Just yesterday i was using my laptop with arch linux with the brightness turned all the way down, as of course it saves battery
but now i turn it on today and the screen is at maximum brightness, and every time i try to change it it just says (in kernel.log) :
Sep 8 10:28:46 Polygon kernel: ACPI: Failed to switch the brightness
Sep 8 10:28:46 Polygon kernel: ACPI: Failed to switch the brightness
so...what got upgraded that broke this? does anyone else have this problem?
here is the past few days of my pacman.log: (it has some entries for kernel-my, a custom compiled kernel, but i get no screen brightness control on my custom compiled kernel, or the default arch one)

Do you happen to know what package broke this? I had this issue a couple weeks ago, and just recently it reappeared.

Flashcards for screen brightness no longer work after BIOS upgrade

I have a Toshiba Satellite T135D/1320S laptop, and last night I upgraded the BIOS to v1.90 under the recently released recall notice. AFter installing the BIOS, however, the Flashcard brightness controls no longer work. Whenever I press FN-6 or FN-7, the screen brightness Flashcard pops up and the toggle on the slider bar moves back and forth, but the brightness of the screen does not change.
I have disabled and re-enabled the Flashcards as suggested in a separate forum, and I've also downloaded the most recent display driver (AMD display driver v8.615). Neither effort corrected the problem.
Anyone have any other suggestions?

Satellite T135D-S1320
Sometimes it helps to reset the machine. With the battery and AC adapter removed, close the Power switch for half-a-minute. Re-attach those, press the Power button to turn the computer on, and then immediately press the F2 key while the Toshiba logo is displayed. Press F9 to restore the BIOS default settings, press F10, and then select Yes (Exit Saving Changes). The computer will restart.
Another things to try is reinstalling the TVAP.

Default Display brightness is too high.

Hi, i am using latest B2G 2.2 [2014-10-08, flame phone]
Default display brightness almost 90%,
Every time i update firmware, i set this value to 10%.
i think this value is too high, it consume more battery.

Hi, my point is default value is too high,
it affect battery life.
user some time forget set this value,
so i think this value should be changed by default.
now, i set this value to 0%
indoor, i can see my flame screen clearly with 0%

Simulating a screen brightness control

I am trying to simulate a screen brightness control on a training tool for locomotive driver console. This console has 8 function buttons, which are used to navigate to various screens depending on the scrren currently displayed. There is another button that is used to control the brightness of the display and I want to simulate this by pressing the button and displaying a semi transparent rectangle over the screen. I can do it for a single screen using the advanced actions but I don't know how to have this work on all screens without repeating the process for every slide. I tried to put this feature in the Master sldie but with no joy
I have an image of the device front panel on a Master slide and I am have created moveable buttons on each subsequent slide to navigate to the relevant images I am navigating through.
If anyone has any helpful hints on how to achieve this I would appreciate it.
Cheers
Greg

Hi Greg,
I felt sad when you mentioned the version 5, had hoped you were at least at 5.5. My idea was to create the 'dimming' rectangle on the first slide
and time it for the rest of the project. The option 'always on top' should be checked. In 5.5 and 6 it is possible to show/hide that rectangle on all the slides, but in 5.0 you can only hide the rectangle on other slides than the first where it really is. This was a less known improvement on 5.5 due to my begging to the engineers. That way you could create one advanced action to be attached to all the buttons, without any editing because the rectangle always had the same ID.
In CP6 it would be even easier: a shape button has all the functionalities of a normal button but can be also be timed for the rest of the project: only one shape button with one advanced action would have been needed. Have a look at this blog post: http://lilybiri.posterous.com/why-i-like-shape-buttons-captivate-6
The idea was to make that rectangle initially invisible, and show it when the button to dim was pressed with an (advanced) action. Now I can only offer some tips to make the cumbersome process of editing shorter, you'll need a rectangle on each slide, and will have to edit the advanced action for each button to point to the correct rectangle:
create rectangle and button, with its advanced action for the first slide (and test it) before copying both at once to all the other slides
label first the button and have the number of the slide in the label (like Bt_x where x=slide number)
it is possible then to use the same name for the advanced action to be triggered by the button
before copying: if those rectangles are the only ones, you can keep the default names for them
the copied buttons will get their proper ID, I would relabel them on the slide, go then to the advanced action, duplicate and edit it
So sorry,
Lilybiri

Is there a way to save keyboard backlight and screen brightness settings?

It seems like my settings for the keyboard backlight and screen brightness reset to some sort of default after I don't use my macair for an extended period of time. Is there a way to change these settings so it always stays at what it was last left on?

Are you making the changes through System Preferences? If not, try that and they should hold.

HAL and screen brightness

So for some reason I could change screen brightness, but only by setting the default in gnome-power-manager. In order to get the function keys to work too I had to play around with HAL config (using an example I found in an ubuntu bug report)
Given that HAL is now deprecated, what is replacing it for handling screen brightness?

pl give the details of your graphics card. in some cases you need to use setpci command. Most of the Intel integrated graphics work out of box. For latest nvidia cards still some issues to be resolved.

Adjust Screen Brightness in Energy Saver modes?

Can I set a custom screen brightness level in both Battery and Power Adapter modes? The Mac seems to always default to a certain level, but can this be changed?

Nope - on my wife's MB (i.e. 13" MacBook, unibody/late 2008), there's no 'custom setting' or 'Details' when clicking on the menu bar battery icon. There is a shortcut to the Energy Saver preference pane, but no option to control brightness in that preference pane other than the checkbox I mentioned above. You can set timers for display sleep, etc., of course.
So, what I see on my MBP, what I see on my wife's MB, and what you're seeing on your MBP seem to be the same. If you have access to a MacBook, check again - if you find the setting your thinking of, post a screenshot...

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

@johnt7225,
Appreciate if you could try running TVSU and Windows Update to ensure all the drivers are installed.
Also is X-Rite a default software which comes with the W520? (I am unable to confirm this as I do not have a W520 to test on) ...
If X-Rite is the one acting up and causing the screen brightness adjustment to not work, I would need to escalate this to engineering.
Thanks Johnt725.
