Win on Bootcamp brightness issue

Hi,
I am running bootcamp on MB (late 2008), with Win Vista (32-bit). The screen brightness on the lower end is stuck to an insanely high level (around 50% of the MacOS level) and is proving to be a considerable strain on the eyes. What might the issue be, and how can it be resolved?
Thanks!

Are you trying to change brightness via that boot camp diamond icon in the system tray? Have you also disabled adaptive brightness in power settings?

Windows 8 Bootcamp Brightness Issue

I have a MacBook Pro with Retina Desplay 15" with bootcamp installed with Windows 8. I use an LCD Cinema display at my desk for more screen space and it works fine when I'm using OSX but not with Windows 8. No matter how I change the settings I can't get the brightness on the display to change. It is always at the highest settting and it is super uncomfortable to use. It may be a problem with Windows 8 and extra displays but that would be really weird for an OS like Windows.
Does anyone know how to fix this? It would be a great help.

Blackberry needs to sort out he brightness issue on the Q10 - Its very bad

Blackberry needs to release an update for its Q10 device ASAP. The device has brightness issues since it was launched. In a response to a Forum member's complaint about the screen dimness, a support staff here said that's how the device is made with no auto-brightness toggle to conserve battery. I believe customers should be given the options to turn on or off this option as they wish. Please fix this problem BB

No he doesnt have a screen problem Jason. It is the Q10 that has a screen problem. Stop misleading people here. Blackberry needs to come up with a fix. The fact that they are not even responding to peoples' concerns on the Forum shows why they will continue to suffer pooor sales.
I am extremely disapointed at Blackberry!!

HP Beats Special Edition 15-p030nr Notebook PC (ENERGY STAR) screen brightness issue

I'm haing a screen brightness issue on my HP Beats Special Edition 15-p030nr Notebook PC (ENERGY STAR). I upgraded from 8.1 and the F2/F3 keys to dim or brighten screen do not function. Any suggestions besides reverting back to 8.1.? Not sure if I had the screen dimmed all the way or brightened all the way when it was upgrading, or if it even mattered.

Auto-Brightness Issue. It randomly worked, then stop working all together.

Auto-Brightness Issue.
It randomly worked before, now it's not giving off any brightness at all. Unfortunately it stopped coming on all together. I tried updating it Itunes and it comes back on but tried to restore my Ipod touch. After restoring it, it said "restore error -50" and the backlight STILL doesn't come on, not even a flicker. PLEASE HELP!!!

Okay I tried to restore using iTunes and a little screen came up stating: An error occured while restoring this iPod (-50). I don't know what that means. It still ask do I want to continue to restore, but always gives me that same message. To make matters even worse, there is no Apple store in my town. The nearest is 3 hours away.

Windows 8 Bootcamp Low Brightness Issue?

Hi There
I have had my MacBook for 6 months now. Due to a new course I have taken up, I decided to partition my hard drive using the preinstalled bootcamp application. I used windows 7 home premium that I purchased, everything was fine with it after some tinkering and downloading the software unitility files from my Mac OS X and placing the files in Windows 7 and etc. I then upgraded to windows 8 Pro and since I have done this (it installed perfectly and runs beautifully) my brightness has automatically decreased. When I increase the screen brightness to full it is only half as bright as it was when running Mac OS X or Windows 7. When I turn the brightness down the screen display dims completely a little under half way down the brightness statues bar.
I have tried:
- Adjusting the adnvanced brightness settings on Windows 8 as instructed on WiseGeek or some what website (I believe this did not work as it was a guide for an automatic self adjusting brightness glitch)
- Adjusting a certain brightness level file in the registry editor in Windows 8 that was to do with Nvidia- but the file that they told me to look for I could not locate (maybe this is the issue; I lack this file?)
Any help would be much appreciated; please do not hesitate to ask for any extra information.
Many thanks

Windows 7 install on late 2011 MacBook Pro without bootcamp (performance issues)

Hey guys I'm hoping I can get this issue resolved. I have purchased a late 2011 MacBook Pro (radeon 6750m 1gig). I installed a fresh copy of windows 7 without bootcamp. Having real issues with game performance like world of Warcraft. I have done this with an older unibody Mac and it ran great (for any non believer)... But now this time around I'm getting horrible fps in game. I'm thinking it may be driver related it buy I am having trouble finding the right drivers to see if that's then issue. Any help on this would be greatly appreciated.

That is completely false. There is no real need to leave OS X on the Mac if you don't want to, especially with Win 7 or 8. That may of been true with Windows XP but not anymore.
The problem with leaving OS X installed is then you are really limited with what you can do with the drive. You can only have one Windows partition and if you fool with it at all Windows will no longer boot. you can't even change the OS X partition otherwise Windows would boot
Windows 7 will install all by itself. No need for any Boot loaders or Hack Boot system. Pop the Win 7 DVD in the DVD drive and restart. Windows will be installed all by itself. But you do need the Apple support files.
In the end if you are going to run Windows on a computer by itself then you really should not buy a Mac. The hardware is the same and as to the OPs perceived better built quality I personally do not see it. And if you actually read some of the posts on this and other Mac forums you will see that perceived build quality is just a bunch of hype, in my opinion.
To the OP. You aren't missing anything.
If you had carefully read what I wrote, I merely said that doing the install on a blank drive wasn't a good idea. That's because it can create issues the OP is having. A Mac's hardware is no different than a comparable Windows machine, but the EFI/BIOS/Firmware is. Macs are in something of a no-man's land in this regard, as they have neither an old-school BIOS or modern UEFI of recent Windows-based notebooks. I'm willing to bet that the performance problems the OP is having relates to the fact that a straight EFI install on a modern MBP "enables" (for lack of a better word) automatic graphic switching. The capability manifests, but the functionality is not there. Enterprising individuals have been trying to get graphic switching in Windows to work as it does on the OS X side ever since MacBooks debuted with this abliity but with zero success.
Using Boot Camp bypasses this, as the discreet GPU is enabled full-time in Windows. Thus, you will realize proper performance.
As far as perceived build quality, Apple machines are at the high end of the consumer notebook spectrum. They're certainly better than most of the other machines you can pick up at your local Best Buy, but they fall short of business-class machines such as the Dell Latitude/Precision, HP ProBook/EliteBook, and Lenovo ThinkPad.

BootCamp Driver issue on macbook pro mid 2010

Hello, i am trying to install a dual boot osx/win XP on my macbook pro 7.1 mid 2010, i partitioned the ssd drive in half and used bootcamp to install windows, all fine except for some drivers, i can't find them anywhere, they are:
- Audio Device on HIgh Definition Audio Bus
- System management bus controller
- Video controller (VGA compatible) (this should be a nvidia 320m)
- Coprocessor
The have the classic yellow triangle symbols meaning that there's no driver installed, so where i can find these drivers ? I own the original SnowLeopard DVD there seem to be some drivers inside but wont't install...
Form my uses i need full graphic acceleration, so at least i need the nvidia 320m driver, i thins that using driver from nvidia site isn't a good idea, i should use apple drivers so if you can provide them i will appreciate...

Once you have XP installed, it is independent of BC. My suggestion is to try the 4.0.4033 drivers.

Apple Cinema Display 23" brightness issue while using with Microsoft Vista

Hello there,
I have the following issue and was wondering if someone has an idea what the reason is or what can I do to fix this:
I have a 23" Apple Cinema Display running with a MacPro 2,8 GHz. When I switch to PC using BootCamp 2.1 with Windows Vista Service Pack 1 32bit the screen becomes extremely dark.
At first, on the PC side, the display has the correct brightness but after two seconds it switches to a very low brightness setting.
When I go back to the Mac side the brightness setting on my Cinema Display has changed to the lowest point.
I also have a MacBookPro, with Microsoft XP installed also using BootCamp (I cannot find the version of this Boot Camp, but it is an earlier version) to change to PC. In XP, there is a driver installed that allows me to use a slider on the PC to control the monitor brightness. But with Vista this slider is nonexistent.
I already tried changing the graphic's card NVIDIA 8800 driver to see if I can manipulate the brightness on the monitor. I realized there is brigthness slider on the Nvidia driver, but when you make brighter, the colors just get messed up, and the brightness stays as dark as before.
We have lately upgraded to Snow Leopard and had installed Spyder on the Mac side to create a monitor profile for the Cinema Display. I already deleted the profile to see if there is a change. Nothing. I already went back in time on my PC (Restore Point), also nothing.
Could I download a driver for Vista, so that I have a brightness slider on the PC side, so that I can adequately change the brightness to its correct setting.
It is amazing how the lack of correct brightness in a monitor, can ruin your entire working day! Very frustrating!
It would be greatly appreciated if someone has a solution for this issue! Thanks a lot!
Emil

Okay, I came across a thread that implies there is a problem with using the Apple ADC-to-DVI adapter to attach the older "acrylic" 23" Cinema Display to a Mac Pro DVI graphics card. Basically, the workaround is to NOT use the USB part of the adapter (disconnect it).
1) In OS X, set the desired display brightness.
2) Disconnect the USB cable coming from the converter to the Mac.
3) Restart into Windows.
The brightness setting should now remain as it was under OS X.
Confirmed to work on my Mac Pro v1,1 (dual 2.66 Core 2 Duo) with nVidia GeForce 7300 GT video card running Windows 7 x64.
Link here: <http://forums.macrumors.com/showthread.php?t=790910> for credit to resolution.
Of course, you lose the functionality of the 2-port built-in USB hub in the Cinema Display, but an external USB hub can make up for that.

Windows 8 Brightness Issue.

Hi everybody,
im running OSX 10.7.5 Lion with Bootcamp 4.0.4 on my MBP (late 2011, i7, 15"). Recently i upgraded my windows 7 to windows 8. and downloaded bootcamp 4.0 via TPB (since Apple didnt have the drivers on their website). Everything installed flawlessly apart from the Display drivers i believe because the brightness remains very dim even though it shows a 100% in windows.
It's really annoying, this problem - is there any fix ? is it so that all Win 8 users will have to wait for an official update to be rolled out by apple ?
thank you

Apple hasn't released Windows 8 drivers for Bootcamp so yeah you have to wait for those before you can expect things to work flawlessly.

How good is wireless networking under Win XP & BootCamp?

Hello,
I'm heading off to business school in the fall and I need to run Windows XP (some of the Excel plugins for intro finance classes wont work in Mac Excel and there are some Windows specific programs we will be using). I just bought a Dell Laptop and am going to return it, as it came with a defective hardware driver - I believe its for the bluetooth, but the moronic tech support based in India can't solve the problem. I'm tired of all the blue screen crashes!
I'm thinking of buying a MacBook Pro and running XP under BootCamp. That way I'll get to use OS X and iLife also. How well does wireless networking work in XP? Any known coonectivity issues/problems? This is very important for me; my school's entire building has a 802.11b wireless setup and I have to be able to connect under Win XP.
On a more general note, reading these forums there seems to be a lot of problems with the MacBook Pro, i.e., heating issues being the most major. I don't know how serious these issues are. Should I go ahead and buy now or hold off on my purchase for a couple months and wait for these issues to be resolved?
Any relevant advice would be appreciated. thanks.

It's a good computer. Wireless works like a charm both in XP and OSX. There doesn't seem to be a WEP key index setting in OSX though.
There are obviously a lot of unacceptable quality flaws with the current MBPs. The only problems I've had are the notorious hi-frequency whine and a keyboard with tipping keys which is going in for repair.
If you get one without any flaws, in my opinion, the only question mark in deciding to get one or not is if you can live with starting up and closing photobooth on every OSX-boot to get rid of the whine as it doesn't seem to be fixed in the near future. If you can - get one.
Good luck.

Win 8: bootcamp or EFI install?

Im ready to try win 8.
Should I go old way with bootcamp or straight EFI? Ive read that going EFI might lead to driver issues, especially nvidia stuff. Is that true?
Which one should I pick?

Hello timelover
If you use Boot Camp to install Windows 8 it will ensure that you will get all the appropriate drivers after you install Windows to make sure that all the hardware works for you.

Windows 8 via Bootcamp Brightness Problem, Buttons working.

I've installed windows 8 via bootcamp on my 2011 mbp and installed the drivers from apple. But the brightness(backlight off my screen can't go to full, except the first seconds when booting into windows. When is push the function keys the brightness doesn't go higher. Because the windows brightness menu says that the screen is at full brightness. When I lower the brightness (In the menu or with the buttons) the screen goes completly black when the bar says that the brightness is at a quater. Does anyone have any solutions? If you guys need screenshot I can provide. Thnx in advance!

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

Very slow wine game/nouveau driver issue

Hello everyone, I'm trying to play a game (Civ 4) using wine. However, it was extremely laggy, and since it runs well on Windows (I have dualboot) plus it's not a very recent game and my laptop is reasonnably well-equipped, I thought it should work well on arch as well. Here is the link in the wine db. I should also add that I'm a very novice wine user so that might well be the (a) source of problem(s). Apart from the lagging, according to the sensors, the CPU's temperature rose from ~50°C to ~100°C within about A MINUTE.
I checked cpupower to see that the cpu was allowed to run at max speed and tried optirun to use the NVIDIA graphics card rather than the Intel graphics card I have installed. I'm by no means sure that the drivers are installed or configured properly by the way...
Starting with optirun looked to work (the loading screen came up) but when the main window should've been loaded, the application terminated with the following output:
err:winediag:wined3d_dll_init The GLSL shader backend has been disabled. You get to keep all the pieces if it breaks.
libGL error: dlopen /usr/lib32/xorg/modules/dri/nouveau_dri.so failed (/usr/lib32/xorg/modules/dri/nouveau_dri.so: wrong ELF class: ELFCLASS64)
libGL error: unable to load driver: nouveau_dri.so
libGL error: driver pointer missing
libGL error: failed to load driver: nouveau
libGL error: dlopen /usr/lib32/xorg/modules/dri/i965_dri.so failed (/usr/lib32/xorg/modules/dri/i965_dri.so: cannot open shared object file: No such file or directory)
libGL error: unable to load driver: i965_dri.so
libGL error: driver pointer missing
libGL error: failed to load driver: i965
[VGL] ERROR: glXCreateContextAttribsARB symbol not loaded
terminate called without an active exception
Before today I only used optirun for VLC (though I don't really see a difference) and to check whether it would run with glxgears. Neither case had any problems. I tried softlinking nouveau_dri.so from the "/usr/lib/..." to the "/usr/lib32/..." directory as well as copying it but neither helped.
Some info:
Graphic cards:
01:00.0 3D controller: NVIDIA Corporation GF117M [GeForce 610M/710M/820M / GT 620M/625M/630M/720M] (rev ff)
00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)
Packages:
local/xf86-video-intel 2.99.916-2 (xorg-drivers xorg)
X.org Intel i810/i830/i915/945G/G965+ video drivers
local/xf86-video-nouveau 1.0.11-1 (xorg-drivers xorg)
Open Source 2D acceleration driver for nVidia cards
local/nouveau-dri 10.2.8-1
Mesa drivers for Nouveau
local/bumblebee 3.2.1-3
NVIDIA Optimus support for Linux through VirtualGL
Some advice how to fix the driver issue or about what else might be causing the problems is greatly appreciated!

Besides agreeing with the notion above, you lack lib32-nouveau-dri and thus are unable to use acceleration with 32bit programs which is the undelying issue here.

Laptop-mode / laptop-mode-tools lcd brightness issue

I have an issue with my lcd brightness config in laptop-mode tools
here is the brightness values
[venky@ARCHROCKS ~]$ cat /proc/acpi/video/VID/LCD/brightness
levels: 72 24 12 24 36 48 60 72 84 100
current: 72
[venky@ARCHROCKS ~]$
following is my lcd-bightness.conf file under /etc/laptop-mode/conf.d
# Configuration file for Laptop Mode Tools module lcd-brightness.
# For more information, consult the laptop-mode.conf(8) manual page.
# LCD brightness settings
# Using these settings, you can make laptop mode tools automatically adjust
# your LCD's brightness settings. The settings are extremely simple -- they
# only allow for the execution of a command, nothing more. The reason for this
# is that LCD brightness settings are very different between laptop vendors.
# Suggestions for commands:
# * If your system has the file "/proc/acpi/video/VID/LCD/brightness" (VID may
# be VID1 or similar), use this file as BRIGHTNESS_OUTPUT, and use
# the command "echo <value>". The possible values can be listed using the
# command:
# cat /proc/acpi/video/VID/LCD/brightness
# * If you have a file /sys/class/backlight/.../brightness, then you can use
# that file as BRIGHTNESS_OUTPUT, and the command "echo <value>".
# As far as I understand it the values are between 0 and
# the value contained in the file /sys/class/backlight/.../max_brightness.
# * For Toshiba laptops, use the command "toshset" with the -lcd or -inten
# command. Read the toshset(1) manual page for more information on the
# parameters for this command. If you use this command, set
# BRIGHTNESS_OUTPUT to "/dev/null".
# IMPORTANT: In versions 1.36 and earlier, these settings were included in the
# main laptop-mode.conf configuration file. If they are still present, they
# overrule the settings in this file. To fix this, simply delete the settings
# from the main config file.
# Should laptop mode tools control LCD brightness?
CONTROL_BRIGHTNESS=1
# Commands to execute to set the brightness on your LCD
BATT_BRIGHTNESS_COMMAND="echo 24"
LM_AC_BRIGHTNESS_COMMAND="echo 100"
NOLM_AC_BRIGHTNESS_COMMAND="echo 72"
BRIGHTNESS_OUTPUT="/proc/acpi/video/VID/LCD/brightness"
so basically while in AC power i want full brightness when on battery i want one notch more than the minimum brightness and when laptop-mode is not running i want 2 notches less than maximum brightness.
the battery mode works fine when i unplug the computer but when i replug the AC power it goes to 72 instead of 100. I mean laptop mode is running coz when I remove ac power it goes to 24 again.
Am I doing something wrong?

When you plug in AC power, laptop-mode probably turns down, so LCD brightness is set to 72. It depends on if you have set in /etc/laptop-mode/laptop-mode.conf ENABLE_LAPTOP_MODE_ON_AC to 0 or 1.
