Can't Turn of keyboard backlight in system preferences after installing Lion.

After installing OSX Lion backlight on the keyboard on my Macbook Pro will not shut off even though it says it's not activated in system preferences. Is anybody else having this problem?

Ditto!
How did they miss it?
Can we expect a fix in a .0.1 release?

Can not turn on keyboard backlight using f5 f6 or settings, Lion, 2.4 GHz Intel Core 2 Duo

keyboard brightness panel appears with fn+F5 orF6 but has the circle/strikethrough and does not adjust . Auto brightness unselected in preferences ... did an SMC reset and boot of course.

Have you tried a pram reset? It most likely won't help, but it don't hurt to try. Also, make a test user to see if you have the same problem. Also try it in safe mode. Post up the results, and we can go from there.

Udev rules to turn off keyboard backlight on Asus UX32VD AFTER login

Hi,
I would like to turn off the keyboard backlight everytime my laptop starts.
I looked at :
https://wiki.archlinux.org/index.php/As … _Backlight
So I created a rule :
/etc/udev/rules.d/kbd_backlight.rules
SUBSYSTEM=="leds", ACTION=="add", KERNEL=="asus::kbd_backlight",DRIVERS=="asus-nb-wmi", ATTR{brightness}="0"
It works quite fine, after the boot the keyboard turns OFF.
But at GNOME login it goes ON again.
I found this :
https://wiki.archlinux.org/index.php/Ba … ht_service
and masked
systemctl mask systemd-backlight@leds:asus::kbd_backlight.service
No more success...
On grep later I masked this one :
systemctl mask sys-devices-platform-asus\x2dnb\x2dwmi-leds-asus::kbd_backlight.device
Nothing new.
On more grep and I commented this :
/lib64/udev/rules.d/99-systemd.rules
# SUBSYSTEM=="leds", KERNEL=="*kbd_backlight", TAG+="systemd", IMPORT{builtin}="path_id", ENV{SYSTEMD_WANTS}+="systemd-backlight@leds:$name.service"
I tried to understand a bit more with this, but without success:
https://wiki.archlinux.org/index.php/Ud … f_a_device
udevadm info -a -p /sys/class/leds/asus\:\:kbd_backlight
Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.
looking at device '/devices/platform/asus-nb-wmi/leds/asus::kbd_backlight':
KERNEL=="asus::kbd_backlight"
SUBSYSTEM=="leds"
DRIVER==""
ATTR{brightness}=="0"
ATTR{max_brightness}=="3"
ATTR{trigger}=="[none] cpu0 cpu1 cpu2 cpu3 AC0-online rfkill0 phy0rx phy0tx phy0assoc phy0radio BAT0-charging-or-full BAT0-charging BAT0-full BAT0-charging-blink-full-solid rfkill2 rfkill3 "
looking at parent device '/devices/platform/asus-nb-wmi':
KERNELS=="asus-nb-wmi"
SUBSYSTEMS=="platform"
DRIVERS=="asus-nb-wmi"
ATTRS{lid_resume}=="0"
looking at parent device '/devices/platform':
KERNELS=="platform"
SUBSYSTEMS==""
DRIVERS==""
Any idea ?
Thanks!

This is driving me crazy...
At GRUB time the keyboard backlight goes on.
UDEV SCRIPT
/etc/udev/rules.d/kbd_backlight.rules
SUBSYSTEM=="leds", ACTION=="add", KERNEL=="asus::kbd_backlight",DRIVERS=="asus-nb-wmi", ATTR{brightness}="0"
=> turns it off later, more or less when the filesystem is loaded, but when gdm (login/passwd) starts it turns on again.
SYSTEMD SCRIPT
After some fight with systemd I could do a script (the tricky part was to start it at the good "level")
/etc/systemd/system/kbd_backlight_off.service
[Unit]
Description=Turns off the keyboard backlight
Requires=upower.service graphical.target network.target
After=upower.service graphical.target network.target
[Service]
Type=oneshot
RemainAfterExit=no
ExecStart= /usr/bin/dbus-send --type=method_call --system --dest=org.freedesktop.UPower /org/freedesktop/UPower/KbdBacklight org.freedesktop.UPower.KbdBacklight.SetBrightness "int32:0"
[Install]
WantedBy=graphical.target
=> useless, adds nothing to udev (standalone it has the same effect than the udev script)
DESKTOP AUTOSTART SCRIPT
.config/autostart/kbd_backlight_off.desktop
[Desktop Entry]
Type=Application
Exec=dbus-send --type=method_call --print-reply=literal --system --dest='org.freedesktop.UPower' '/org/freedesktop/UPower/KbdBacklight' 'org.freedesktop.UPower.KbdBacklight.SetBrightness' "int32:0"
Hidden=false
X-GNOME-Autostart-enabled=true
Name[en_US]=kbd_backlight_off
Name=kbd_backlight_off
Comment[en_US]=kbd_backlight_off
Comment=kbd_backlight_off
=> it turns if off after the login, but when the background wallpaper is displayed it goes on again...
Shouldn't be so difficult to turn the keyboard backlight off, from the boot time... What am I missing ???

Not opening system preferences after Mountain Lion upgrade

What I expereinced today was that I was unable to open system receiving and error about (Notifications, iCloud...) not being able to open and then needing to restart... upon hitting OK it gave the same message again. I went into appications using the finder and then clicked on the [system preferences] and then selected [more info] from the menu. The get info box said that the system preferences were running in 32-bit mode. I unclicked 32-bit mode and then tried running the offending system preferences again and it worked as expected. Apparently there is some kind of gotcha about running specific preferences in 32-bit mode in the new update?
I hope that this works for those of you running into what I experienced this morning.
Peace

Hi
Thanks for your replies. It isn't a gmail account - it's a domain account hosted by Domainmonster. Also my iCloud email is now intermittent :(
I've checked the SSL settings/authentication settings and everything is as it should be according to the email provider. It's frustrating as it was working fine for exactly a week following the upgrade and then just stopped sending mail. Also, the intermittent nature of the problem on the iCloud account now suggests to me at least that this is a problem that isn't the users fault?
I've downloaded thunderbird and all my accounts are working perfectly through that so for the time being at least I'm staying with the upgrade and hoping that a future apple update might address the issue. From the reading around I've done this seems to be a problem some people are having that tends to be intermittent in nature and resolved temporarily but not completely at the users end of things.
I've given up for now thanks to the fact that Thunderbird is working and I can still access my accounts on my iPhone. Very frustrating though when things don't make sense :) I mean, if it was going to stop working I would expect it to have stopped when I upgraded - not functioned fine for a while afterwards and then just literally send a mail one minute and refuse to send the next five minutes later. Also with my new problem today of Mail and my .me account - randomly sending mail when it feels like it and stacking mails up in the outbox the next - just doesn't make sense to me :)
If anyone does figure out what's going on I'd be grateful for any ideas/suggestions. Seems weird that all the email accounts function fine through thunderbird but not Mail. So far anyway :)

Missing "sharing" option in system preferences after installing apple remote desktop client version 2.10

Hi All,
I installed a wrong version of Apple remote desktop client , 2.10 and the sharing menu under system preferences vanished. I tried to uninstall the Apple remote desktop with,
http://support.apple.com/kb/HT2577
but no luck, but after restarting the macbook pro with lion 10.7.2, i see my sharing option enabled but when clicked, it says the system preference has to restart and confirming that it restarts in 32 bit mode and even after clciking the sharing option it says, "you can't open sharing preferences because it doesn't work on an intel-based mac"
. So i strongly believe the apple remote desktop is creating the issue.
Can someone help how to fix this please?
Thanks

Same problem here. I manage several remote Macs, but I have one MacBook which I can get no ARD access to (black icon). I can ping the IP, I can SSH into the MacBook, the ARD and Remote Login services are checked ON, the firewall is OFF. The ARD service is configured to allow my admin user full access - however, I get nothing. I have no trouble getting into the other Macs.
Any ideas?

Problems with Mobile Me System Preferences after installing Snow Leopard

I installed Snow Leopard yesterday, and noticed that my calendar was no longer syncing between my mac and my iphone. I opened the system preferences/mobile me pane and my .mac account came up, but when I tried to hit the "sync" pane it just froze. It did this repeatedly. I trashed the system preferences file and tried again, with the same result.
Any ideas? I'd really like my calendars to continue syncing across devices.

I had same issue, this cured it for me...
- Open MobileMe in System Preferences
- Click Advanced
- Click Reset Sync Data
- Select Calendar from drop down menu/pop up list
- (In my case I changed the arrow, to copy all calendar events from my mac to mobileme)
This resets the data in mobile me.
After this the sync function worked as normal & my iPhone syncing was ok as well...
Hope this helps

Can't find a keyboard shortcut in System Preferences...

I'd like to change the command-w shortcut to the F13 key but can't find command-w in the list of keyboard shortcuts. What am I doing wrong?

In which Application?
Say it's the finder, 1st make sure F13 isn't used in Expose/Dashboard, then in KB & Mouse scroll down to Application Keyboard Shortcuts, choose Finder, hit the plus sign, tyope in Close Window, then hit the F13 key, exit, force quit the Finder or restart for it to take effect.

I can't delete anything (movies or songs) from iTunes, after installing Lion

When I select a song or movie and go to edit at the top the delete choice is grayed out and I can't delete anything?

Try using the Delete key on the keyboard.
At least, thats what others are suggesting here -> Can't delete files in iTunes 10.4 (80) OS 10.7 Delete in the edit menu is not hi-lighted?

I can no longer hold down a key and get the character to repeat as say, aaaaa. Instead I get a menu of accented a's, such as àáâäæãåā. I can't find any thing in the System Preferences that allows my to turn this function off

Back up all data before proceeding.
Please triple-click anywhere in the line below on this page to select it:
defaults write -g ApplePressAndHoldEnabled NO
Copy the selected text to the Clipboard by pressing the key combination command-C.
Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window by pressing the key combination command-V. I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key after pasting.
Wait for a new line ending in a dollar sign ($) to appear below what you entered. You can then quit Terminal. Log out or restart the computer.

I can not turn on my backlight onnano 5th gen

There is no setting to turn it on or off completely. If it isn't working, it's probably damaged or faulty and in which case you'll need to send or take your iPod in for service.

Do you have 2-step verification on for your Apple ID? I may have a solution.
When I upgraded to Yosemite and subsequently updated my Apple ID, I would get errors when I tried to sign into iMessage and FaceTime using my apple ID (and my new password), I similarly was not able to sign in. On FaceTime, I would get errors like "unable to sign in at this time" or some times just nothing at all (the spinning 'processing' graphic would grind away until it presumably just timed out).
Turns out that I enabled 2-step notification on for my Apple ID (totally forgot about it, I set it up a couple years ago), and apparently the regular Apple ID password that you choose is not usable when you try to log in to iMessage or FaceTime through the programs themselves (intuitively, this makes sense since these programs do not have a way to prompt you for the "2nd step" code).
To solve, you have to log in to your Apple ID online (appleid.apple.com or whatever), and look for the option to "Generate App-Specific Passwords". These are unique, random passwords which are made to work around issues like these since they can be used in iMessage or FaceTime or what not. This is the same idea as to what you have to do to log into gmail on your iPhone if you have Google 2-step verification on.
This solved my issue (after lots of swearing and hair pulling!). Would have been nice if a I got some sort of warning when updating my Apple ID password that "Hey, you have 2-step enabled. Go make some app-specific passwords or you will lose 5 hours of your life trying to solve this mystery"
Hopefully this may solve yours

Can i re instal it back?
Please advice what to do ....how to cancel signing out....turn off my mac...or re instal icloud...
Thank you

I have the same problem. Unfortunately, the troubleshooting link you added has the first step listed as "Verify that FaceTime is enabled in FaceTime > Preferences" which we (the original poster and I) can't do as our Preferences are greyed out. We can't click on them to verify anything.
In FaceTime itself it's verified my apple id (also double checked via the site) and then it says the email is "verified" but then it freezes and after a minute or so it says "Could not verify the email address. Please check your network connection and try again."
After checking the network connection, it still doesn't work. It's rather frustrating as it all worked fine until about a week or two ago.
Any help would be appreciated.

IMovie has frozen up on me. I've tried rebooting and reinstalling the apps- no help. I can play some of the files- but I can't get into the libraries.Even when I can get something to play the whole system crashes after a few minutes. What can I do?

I desperately need your help. I was working on iMovie last night when the thing froze up on me. I've tried rebooting. I've tried reinstalling the apps. No change. I can play some of the files- although I can't tell which ones will play until they magically appear. I can't get into the project library or the event library. The bar that lets me scroll through the clips is gone. Even when I can get something to play the whole system crashes after a couple of minutes and generates a "problem report" that says "iMovie Quit Unexpectedly". This all started when I was adding cutaways- and one clip just would not load. After I tried several times everything froze up. Have you ever heard of something like this? Maybe I pushed a button or somehow changed a setting? Maybe some of the video is corrupt? What do you recommend?
Thanks for any advice you can offer!

I have tried all the above and nothing seems to work. Any other suggestions?

My system preference, powner off, restart disappeared after installing lion twice! Anybody can help?

After installing Lion on my Imac, the System Preference option in the apple menu (Apple sign on top left side of desktop) has disappeared. In addition, the power off, restart options are gone too. I have reinstalled the Lion twice but the problem hasn't been resolved yet. This is happening when I am logged into adm. user. In other users account, the menu seems to be ok. Any suggestions or recommendation to help me fix this issue?

Let me clarify the issue again:
A number of items have gone missing from my apple menu: Software Update, System Preference, Dock, Recent, Restart, and Shut Down are gone.
All that's left are About, Location, Force Quit, Sleep, and Log Out. Can anybody help?
