Change background of "unlock" screen after iMac is idle

My iMac is set to require password to "unlock" after it has been sitting idle for a while. When the mouse or a key is moved/pressed, the password box appears with a plain black or dark gray background.
I would like to change that color to one that will illuminate whomever has moved the mouse or pressed a key when it might be dark, to aid in video security for the computer.
Does anyone know how this color or graphic might be changed?

See these links for Mavericks. It might work in Lion as well.

See the Gnome_Tips wiki article which contains the answer to this and other questions
Change the Default Background Image
The default background is that zoomed in picture of a green leaf. It appears for newly created users, but more importantly, this is the image shown when the screen is locked. As of 25-Apr-2009, you can find this image here
/usr/share/pixmaps/backgrounds/gnome/background-default.jpg
To change it, simply copy your favorite image to this locate (as root) and rename it.

Change background of "require password after waking" screen?

I have my iMac set to require password after it sits idle for a specified time. Screen saver does it's thing and then when I come back and move the mouse or hit a button, I get a totally black screen with the password field.
I would like to change the color or image of that screen. It is not the same as the "login screen." It does not show the desktop. It's plain, black.
I'm not even sure what to call this view of OSX. Anyone have any insight?

right, i'd just like to add that this issue was solved by installing "proper" ati drivers, or lowering sync and refresh rates in /etc/X11/xorg.conf, one of those

Change Background on my screens

Does anyone Know if their is a way to changes my ipone background to black like found under the accessibilty

I want to have normal looking icons
Mark

If I understand what you are attempting to achieve. Normal looking app icons and inverted colors within the apps like Reminders or Safari. For that he best you can do is go to the Accessibility menu and scroll all the way down. In the Triple-Click Home option set it to Invert Colors. Now when you enter an app that you want the feature triple-click the Home button to activate the feature, when you exit the app triple-click the Home button to change back.

Blank screen after 10 min idling - need to reboot [SOLVED]

I've installed Arch on a Thinkpad Z61M. Everything seemed to go off OK. I have not yet installed X.
After about 12 minutes of inactivity the screen goes black and I cannot revive it. It is not a total lockup because it still responds to the keys (reboot),
I've tried every key press I can think of and have unplugged and plugged hack the power lead.
I fiddled with entries in logind.conf but no difference. By googling I found some recent references to a kernel bug. Is this a possibility?
Last edited by acampbell (2013-05-17 15:59:36)

As I said originally, I have not installed X yet so there is no xset command.
See https://bbs.archlinux.org/viewtopic.php?id=157579 - Not exactly relevant but in the same territory.
The 3,8 kernel seems to be buggy; I tried it on my Debian Sid system and various problems occurred, although not this one. There is quite a lot about it on the Debian users' list.
Is it possible to try a different kernel in Arch?

How to use custom PAM module to unlock screen ?

Hi,
I actually use a custom PAM module for authentificate my users. This is working like a charm with sudo.
I wanted to add it with the login screen, the one that everyone use. I added my config in /etc/pam.d/authorization and everything is working. When I get a box prompting for a password, the plugin is activated. As excepted.
But my problem is that the plugin is not activated when my mac get the unlock screen after being on sleep. You know, the one where your screenpaper is shown and your image. How to do so?
Many thanks.
Regards,
Andy Pilate

Here is how I did it in my app:
<jbo:ApplicationModule id="am" configname="TestAMLocal" releasemode="Stateful" />
<jbo:DataSource id="ds" appid="am" viewobject="TestView" rangesize="3"/>
<%
TestAM am2 = (TestAM) TestAM.useApplicationModule();
am2.TestClient();
%>
Hope this helps.

New iMac is stuck on grey apple screen after restart from Migration Assistant

New iMac is stuck on grey apple screen after startup. It is a 3.4GHz Quad-core Intel Core i5 running OS 10.9.4. The problem occurred after a migration from my older 2009 iMac which is running Snow Leopard 10.6.6. When the restart occurred from Migration Assistant, the new computer will not boot up to the login screen. Disk utility did not solve problem. Followed instructions for a soft reinstall of Mavericks but that also did not solve problem. Any suggestions?

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

Hi...
My name is Turgay and have been using computer since 1982... 2 years ago, because of my friend's advice, i bought an iMac... It was the first Mac that i use... Till that, i was using normal PC's...
I bought an 24" iMac on July 2009 and started to use... I realized that i spent my 27 years for using (fixing) computers. Because the Mac was perfect. After iMac, i was really fine with my computer... But after something, that doesn't bother me, happened. The screen started to get cloudy and black... And it increased. Because of this i took my iMac to your authorised distributor http://www.bilkom.com.tr...
They changed my screen but in 2 months it happened 3 times and i wanted them to change my iMac with new one, under customer laws... In our country, the device must be changed with new one if the same problem occurs in 3 months. Because i know the customer satisfaction of Apple, i didn' worry about it but Bilkom refused my will... I spoke with them for 2 months but nothing happened, they just told me, it' not our problem.
Because of this speech, i sued them on June 2011... Last week, i won the case but just for the return of invoince... It costs 3.200 Turkish Liras (1.800$) and there's no 24" iMac unused... Bilkom again refused to give me an iMac... I thought that Apple's customer satisfaction can't be like this... I didn't write anything to Apple till now but if i can't get an iMac, i must return to normal PC after 2 years... And i don't want that... I offered an iMac 27" with core i7... No matter Bilkom accepts or not, they don't care of me... I'm a customer, they should do... I've never seen such a like company. I hope the real Apple will help my problem and save me from Bilkom...
Waiting for your reply... Thanks and regards...

Have reformatted my Imac using original discs (installed leopard (10.5)) tried to do the software update but it cant download the itunes update and when it gets to the configure update screen after restart for main update, it just gets stuck. HELP!

have reformatted my Imac using original discs (installed leopard (10.5)) tried to do the software update but it cant download the itunes update and when it gets to the configure update screen after restart for main update, it just gets stuck. HELP!
The configure bar gets about an 1/8 full and then just does nothing. I think its lists the update as combo update? cant remember with out checking.
I have tried to do the disk verify and repair but this has made no difference.
Please let me know what i need to do, I have reformatted the mac just to start over as was clogged with a lot of useless data, I had installed lion (10.7) from the app store previously and now cant seem to find a way to re install lion. I hope I dont need to pay for it again?

If you erased your hard drive, you'll need to reinstll OS X 10.6 Snow Leopard to access the App store. You won't have to pay for OS X 10.7 Lion again. Did you try booting to the recovery partition by holding the command and r keys down? If that's still there, you can reinstall OS X 10.7 from there.
If you're looking to install the current iTunes, you need OS X 10.6.8 at a minimum.
If you're still trying to update OS X 10.5 Leopard, you can download the combo update from here. Download, use Disk Utility to repair permissions, apply the update, then repair permissions again. That will take you to OS X 10.5.8.
