Reduce screen brightness too soon on Highest performance setting

I think this issue is a fairly new one. I'm on Tiger with the latest security updates. But I want the screen brightness reduced, like an hour after no activity, not one minute while I'm on power adapter. Every setting is set like I want, Highest, etc for when it is on power. I can understand on battery I want it to be aggressive on saving power, but for AC ...

Hmmm, just checked on my iMac, and that is the file that holds that setting... does that stay unchecked between reboots?
That file also would seem to hold the Settings to use on Batery, but I wonder if Battery Models also have some other file that might affect it... can't tell here.
I wonder where the Performance settings all are?

How to reduce screen brightness below standard level

Hi !
How to reduce screen brightness below standard level in ThinkPad T520 ?
I think it is possible somehow, but I don't know how. I reduced brightness to zero using Fn key + End key, but it's not enough, I want to make screen darker, because my eyes get tired.
Solved!

The latest Intel graphics driver (from Lenovo) is here:
http://support.lenovo.com/us/en/downloads/migr-77038
This should provide a decent lower bound to brightness. If the install complains about unsupported hardware, force the install using Device Manager and Have Disk. (Something like this: http://forums.laptopvideo2go.com/topic/11997-have-disk-method-for-windows-7-vista/ )
If that didn't work, try f.lux (https://justgetflux.com/). It has a software dimming feature (of course, this loses contrast).

Screen brightness too high

Hello, I have had my first blackberry for a few days now, and I'm in trouble with the screen brightness. I have sensitives eyes ad even at the lowest settings, the brightness is hurtful in dark rooms. It does not seem to be a bug nor a material issue specific to my phone, as most new phones and computers are also too bright. Therefore my question is is there a possibility to lower the screen brightness under the OS preset limit ?I am a developper so even a programmatical solution would be nice. I have only seen outdated posts about this issue on the Internet, with no solution, maybe the problem could be solved in 10.3.2 or in the next versions ? Thanks a lot

Okay thanks, it is posted there : http://supportforums.blackberry.com/t5/Native-Development/Screen-brightness-too-high/td-p/3122861. I also thought about always putting a semi-opaque frame on the foreground, as the android ight filter apps usually do.

Fully Reduced Screen brightness goes up by itself.

Hi everyone,
Not too long ago I realised that when I fully reduce my screen brigtness (to leave my laptop ON before going to sleep), my macbook air automatically (by itself) increases it slightly. In other words, instead of the screen being totally black at night, it becomes bright, which of course is not what I want. It never happened to me before, or may be I have never really paid too much attention to it.
I tried to look into my Energy Saver preferences, but I could not find anything unusual there. Has anyone of you experienced anything similar or may be you have a solution to my problem?
Thank you very much in advance.

Have you tried: Go to system preferences>displays and check off "automatically adjust brightness as ambient light changes" ?

[SOLVED] screen brightness too low when switching tty

I have autologin enabled in LightDM, so when I boot I am taken to my MATE desktop automatically. This happens in the default tty (tty1).
Sometimes I want to switch to a different virtual terminal (e.g., by pressing Control+Alt+F2) without ending my session in tty1. However, most of the time when I do this I find that the brightness in the new tty (e.g., tty2) is so low that I can hardly see the login prompt. When I switch back to tty1 the brightness in the X session is fine. Switching back to tty2 I see that it is still dim. Hitting either the brightness-up or the brightness-down (!?) key on the laptop causes the brightness in tty2 to jump to normal.
Does anyone know how to fix this so that when I switch to a different tty the brightness is at a reasonable level right away? I am on a Lenovo Thinkpad T520 (no Nvidia, just integrated Intel graphics) in case it matters.

As an experiment, I logged in to non-graphic mode in tty1 (by adding "systemd.unit=multi-user.target" to grub2's kernel line), then tried switching ttys. No brightness problems!
As another experiment, I allowed regular boot to my desktop in tty1 (LightDM -> MATE autologin) but then got out of graphical mode by opening a terminal emulator and typing "sudo systemctl isolate multi-user.target". Once I had a cli in tty1 I then tried switching ttys. Again, no brightness problems.
I can conclude that when switching tty's, the new tty is too dim only if I have a graphical session running in tty1. Therefore, I don't think this is a kernel problem. Seems that something related to lightDM or X or MATE running in tty1 is causing the problem.

After Mavericks, at start up, initial screen brightness too high and starting sound too loud, different than I left on previous shutdown. Didn't happen before the update.

I've tried sudo nvram SystemAudioVolume=%80 for the sound, but it works just once... returns next startup's.

The first thing to do is use smartctl to test the drive. Start with the short test ( smartctl -t short /dev/sdX ), and if it passes run the long test ( ... -t long ... ).

MBP 2011 Screen brightness changing regardless of the ambient light

As stated in the subject my brand new MBP 2011 screen brightness changes on its own, yes i know about the ambient light sensor, but my screen is going from med brightness all the way to minimum brightness even though the ambient light is constant. yes I know i can turn it off, but why build in an ambient light feature that just makes the screen go to mimimum brightness when in a well lit room??
or do i have a faulty one??

I too have this problem on my spanking new MacBook Pro. Called AppleCare and they said they weren't aware of this issue.
Meanwhile, this is my 1st mac. Had it for a few weeks now. Decided to open iTunes for the 1st time. The whole MacBook Freezes, no mouse interactivity, reboot required. This happens EVERY time I start iTunes which I no longer do. Apparently it's a known issue which Apple has patched(unsuccessfully). But hey c'mon, I mean iTunes? This is one of the core apps which SHOULD be tested extensively against the hardware. When you consider Apple PROVIDES the hardware, this is simply unacceptable. Unbelievable even. I simply can't believe how poor this is from a major company. But hey my MacBook Pro LOOKS GOOD right, so who cares if it's a technically malfunctioning piece of junk.
Here's my theory. Is part of Apple's patch deliberately reducing screen brightness without user authorisation when the MacBook starts to overheat, all because they know they've been incompetent/negligent with their QA testing and the hardware can't handle the software? If so, why have users not been informed?
I'm from Australia and we have this so-so comedian called Chris Lily who fans have taken to calling a genius, the joke amongst non-fans being the word genius has been dumbed down over the years to be almost meaningless. Anyway, maybe a certified Apple 'genius' can explain the reasoning for the apparently deliberate brightness reductions?

I can't reduce my screen brightness

this happened after i deragraded my system Hp 15-r005nia Notebook Pc from windows 8 to windows 7. ever since then i can't seem to reduce the screen brightness. please i need a solution to this problem.
Thanks i will be anxious to get a souution to this because it really affects my eyes each time i'm working.

Sorry that driver didn't work.
It is for the Celeron N processors but I was hoping it would work for the Pentium N processors too.
Unfortunately, there is no solution to your problem other than to install W7 64 bit if you want to install W7.
There is a W7 64 bit driver for the Pentium N processors.

The screen of my imac always goes to the maximum exposure. Then the light icon on the screen. After reducing the brightness goes my screen after a few minutes back to the maximum intensity with the brightness icon back on my TV screen.

Try resetting the SMC and if that doesn't work then reset the PRAM too.
SMC RESET
Shut down the computer.
Unplug the computer's power cord and all peripherals.
Press and hold the power button for 5 seconds.
Release the power button.
Attach the computers power cable.
Press the power button to turn on the computer.
PRAM RESET
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

How can I reduce the brightness of my screen?

I installed WIndows 7 on my MAC and after installing the boot camp drivers, the screen went really bright.
I reduced the brightness to the lowest setting on my keyboard, but it is still bright.
The problem is not so much on the graphics, its more on the brightness of the white background & black text.

How can I reduce the brightness?
Start menu > control panel > appearance & personalization > display > calibrate color
I would adjust the keyboard setting back to midway before calibrating, this way you have some flexibility to use that again.

Definitly sounds like a physical issue with the phone. I suggest you go to your local Apple Store or Apple Authorized Service Provider for help.

Screen Brightness reduces after Mac OS Update

I had updated my Mac OS to 10.6.3 from 10.6 on my macbook pro. I noticed after rebooting of my system, the screen brightness has reduced considerably. I reset the PRAM and noticed my brightness return back to normal lever but again reduced after login page appeared. Can someone provide me with a solution to the problem..

Hi there,
I experienced exactly the same when I updated one of my Macs recently. I was running the update & the screen reduced it's brightness as it usually does before it goes to sleep & then once it had restarted as part of the installation process, the brightness was more or less at it's minimum setting. I increased it to it's usual setting & this was then retained as usual. You shouldn't notice any further reductions in brightness as I believe this is just due to the screen's powersave process kicking in during the installation.

Satellite P300-P19: screen is too bright

Hi all
I have a P300-P19, the screen is so bright, its set at LEVEL 17.
I have to use FN + F6 to drop it to LEVEL 1 constantly.
Does anyone know how to set it so it stays at the LEVEL you want ?
And is there any other options for contract etc etc
Its even to bright at LEVEL 1 but i do hate bright lights... :-)
Thanks in advance..
Rob

LOL :D if you hate true bright screens so why you buy devices which support such True Bright screen technology?
I love such screens I like it in the LCD TV, external PC LCD and in notebooks...
However, if you want to use constantly low screen brightness then I recommend changing the screen brightness option in the Vista Power settings.
Check the forums HowTo area.
There you can find nice document called How to handle the power managment features of Windows Vista?
Bye

Hello Irobbie:
You pressed the wrong F keys. Press F-10 for dimming the screen. F-11 for brightness. The key board doesn't work then go to control pannell and click on systems on the left bottom click on Performance Information and Tools under Windows upate. Now click on Adjust Power Settings in next window top left side. Now in this window in tne bottom center you will see Sceen Brightness slide the box arrow across bar to desire brightness setting. You are welcome please click on Kudos if this has resolved your issue thank you. frrw

Screen Brightness working strangely on MacBook Pro running 10.8.5

When I try to reduce the brightness of my screen, it goes black on the 5th of about 12 levels, and it won't come back from black until I hit the last (highest) brightness setting. What's up with that?
