Snow Leopard hangs after LDAP login, mouse works, keyboard stops working

Afternoon,
It was suggested that I post my question below in a server forum rather than a client form.
Mike
Morning,
Earlier I posted a question about 10.5 brightness and 10.6. The user will deal with the brightness issue, so that's moot at the moment. I still have an issue with 10.6 hanging.
I have configured 10.6 to authenticate using OpenLDAP from a Red Hat box. The authentication works fine. I have added /home from the same linux box to the list of NFS mounts (Disk Utility->File->NFS Mounts?, I'm not in front of the mac box at this moment to verify). The /home filesystem does get mounted.
Very quickly after logging into a non-local, LDAP account, the mac box becomes useless in that I cannot start any programs, I can't logout, I can't do anything. If I double click on Terminal (Applications->Utilities->Terminal) I get the brief flash like Terminal is starting, but the application never appears on the desktop.
I can still ssh into the mac box. When I ssh in and run top, to see what's consuming the CPU, the machine is idle. My guess right now is every application is timing out or failing to start. I see nothing hogging the CPU nor the network.
When I log in using a local, non-LDAP account the mac box acts as I expect it to when launching applications, looking at NFS, surfing the web, etc.
Any ideas what's going on, what to check for, and how to fix this?
This is an iMac 27". I may need to contact Apple support on this one.
Mike
Additionally, the mouse continues to work, the keyboard stops working (wifi both), and the finder starts reporting -10810 on every application open attempt. I can select the Apple->Logout or Restart options, but nothing happens. I must ssh into the iMac and 'shutdown -r now' to get back to a login so I can login as root to make further changes.
Mike

I was able to grab a crash log if that helps.

  • Apple wireless mouse and keyboard stop working ... now says OS X version and bluetooth incompatible

    For no apparent reason my apple wireless mouse and keyboard stopped working. I was not upgrading or installing anything, the batteries are good, nothing was changed as far as I know. Now bluetooth discovers the paired devices, connects for about 30 seconds, the disconnects ... or stays connected but doesn't work.
    What's happenned ... I'm rushing to finish a big job ... any ideas? I've tried re-pairing but doesn't work ... says that OSX version may be incompatible with device bluetooth ... I'm using Lion so maybe there is another lion problem?

    Hello:
    Barry: What do you mean with "making devices favorites"?
    This is the method:
    Go to system preferences>bluetooth.  Highlight an item in the sidebar.  If detailed information does not appear, click on the little gear and select show more info.  Then click on the gear again and select favorite.
    And how could an hardware-related problem be (temporarily) solved rebooting the OS?
    Intermittent problems are, IMHO, most often caused by hardware.  Restarting will occasionally "fix" problems - why, I do not know.

  • Mouse and keyboard stop working with Mavericks

    This has happened twice now since installing Mavericks.
    I'll be working along, and then all of a sudden, I am not able to click with my mouse and my keyboard stops working. I AM able to move the cursor around on the screen. But, I am not able to click on anything and I can't use the keyboard to force quit the finder. The only way to get unstuck is to press the power button on the front of the Mac to shut it down and then restart.
    I am using a wired Apple Keyboard and a wireless Apple Magic Mouse. My Mac is a MacPro 2 x 2.3 GHz Quad-Core Intel Xeon Mac.
    Like I said. this has never happened before. But it's happened twice since installing Mavericks.

    Everytime I restart my computer, especially for updating maverick, my keyboard and attached mouse (both apple for an Imac) stop working. When I plug in an other keyboard, I can get into my Imac again. Would this SMC apply to this problem as well?
    What should I do?
    thanks, hb

  • Mouse and Keyboard stops working after a while

    Hi, I'm not even sure where to start to find the cause of the problem. I have a normal ps/2 keyboard and USB optical mouse, both of them just stops working after a few hours. The light on the mouse just dies and the keyboard is not responsive at all.  I have to do a hard reboot of my computer. How and where can I diagnose the problem? I noticed the problem started when I upgraded to the latest kernel.

    And then after a while it will just use a new address:
    Oct 31 01:47:15 wdesktop usb 1-1: USB disconnect, address 6
    Oct 31 01:47:15 wdesktop usb 1-1: new low speed USB device using uhci_hcd and address 7
    Oct 31 01:47:16 wdesktop usb 1-1: configuration #1 chosen from 1 choice
    Oct 31 01:47:16 wdesktop input: Microsoft Microsoft Wheel Mouse Optical as /class/input/input8
    Oct 31 01:47:16 wdesktop input,hidraw0: USB HID v1.00 Mouse [Microsoft Microsoft Wheel Mouse Optical] on usb-0000:00:10.0-1
    Then after that my mouse is unusable, the following is shown:
    Oct 31 01:48:41 wdesktop usb 1-1: USB disconnect, address 7
    Oct 31 01:48:41 wdesktop usb 1-1: new low speed USB device using uhci_hcd and address 8
    Oct 31 01:49:13 wdesktop usb 1-1: new low speed USB device using uhci_hcd and address 9
    Oct 31 01:49:45 wdesktop usb 1-1: new low speed USB device using uhci_hcd and address 10
    Oct 31 01:49:56 wdesktop usb 1-1: new low speed USB device using uhci_hcd and address 11
    Oct 31 01:50:08 wdesktop uhci_hcd 0000:00:10.0: Controller not stopped yet!
    Unplugging and plugging the mouse back does not work
    I found a workaround for that by unplugging the mouse, removing the uhci_hcd and adding it back, so:
    sudo rmmod uhci_hcd
    sudo modprobe uhci-hcd
    But I'm still not sure what causes the problem.

  • Mouse and Keyboard stop working after reboot

    So far the computer is working great except for the fact everytime you reboot the keyboard and mouse stop working... I did a clean format x2 and put the service pack on and I am still getting the same problem.
    Anyone have this problem or something similair ? Any ideas ?
    Thanks in advance :-)

    The problem is not your S/W install. It's with the MSI Motherboard. Your best bet is to ask MSI when a fix will be available, or go buy a different board.

  • Mouse and keyboard stop working ocassionally and I have to re-boot the computer. does anyone else have this issue?

    I  have a pwoer Mac with a dual quad processor and current os. If I turn off the computer at night and power up the next day my wireless mouse and keyboard do not work nor does my hardwired mouse. I have to hold the power button to re-boot the computer to get it to work.

    Open console in Applications>Utilities, check the system log for the date/time of the last problem  & the Startup right after that for clues.
    And/or...
    One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
    PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
    Reboot, test again.
    If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.
    Check the System Preferences>Other Row, for 3rd party Pref Panes.
    Also look in these if they exist, some are invisible...

  • T510 Mouse and Keyboard stops working with Windows Update - unable to roll back, happened twice

    My mouse has been working fine for a while but it stopped working followed by the keyboard, I put it down to a Windows update but because Windows 7 keeps bluescreening on a restore point I couldn't recover.  I contacted Lenovo got the rebuild disc for my machine, completely rebuilt it, all working fine, then after 2 days same issue, mouse stopped, keyboard stopped, restore points make no difference.  Does anyone know what windows update is causing this and if there is a fix aside from rebuilding, I can't keep doing this and I need to understand the cause really, not had it with a laptop before.  Gone back to using my old laptop until I can get it sorted.  Does anyone have any ideas?

    I installed the latest drivers via windows update and got the touchpad back, rebooted, it went again.  Netiher the trackpoint or touchpad work.  I then thought rather than focus on drivers check the bios.  I disabled the trackpoint in the bios, still neither works, however if I disable the touchpad in the bios and enable the trackpoint, the trackpoint does consistently work.  I can't explain why the touchpad worked after a touchpad update but now fails, the ultranav driver is installed but if both are enabled in the bios it say it isn't installed, if the trackpoint is enabled it tells me I need to enable both so it clearly knows it's there.  What's curious is that this doesn't happen on the complete clean IBM build.  I can't not turn off windows updates, I'm a developer so Ioad the laptops up with a vast variety of software and I need many of the windows update fixes, either way I am surprised they are conflicting with the touchpad so dramatically.  I can't see it being a virus I'm using two layers of protection and if I blow the machine away and installed the updates via an .iso image (so it's never connected to anything else), I can replicate the problem.  It's feasible it's another piece of software causing the conflict.  Any one have any idea what could be going on or seen it before?

  • External Mouse and Keyboard Stop Working When X220 is Docked and Screen is Closed

    I have an X220 with a docking station, external monitor and external keyboard/mouse.  When I start the laptop from a cold boot and it's docked, my external mouse and keyboard work fine with the screen open or closed.  
    If I undock and redock with the screen closed, the external keyboard doesn't work and the mouse cursor moves, but the mouse buttons don't do anything.  If I open the screen, then the keyboard and mouse work fine.
    I've swapped the keyboard and mouse and still have the same problem, so it's not the kb/mouse.  This is a brand new X220 and the issue has been occurring since it was purchased.
    Any thoughts?

    hey mhambalek,
    hard to say what's going on, though i would recommend heading to http://support.lenovo.com , do a full update of your unit.
    also, if the external keyboard & mouse & monitotor is connected to your unit without the docking station, does the same thing happen?

  • Mouse and Keyboard stop working since Upgrade to Leopard

    I upgraded to Leopard on Friday. Twice today, I've had problems with the mouse/keyboard freezing me out of my MBP. I never had this issue prior to upgrading. The first time today, both the KB and mouse quit. Later in the day, just the KB. Both times were after periods of inactivity. I don't remember the exact scenario leading up to it, but in both cases, a reboot fixed it. I don't have enough detail to (in my mind) justify a trip to the genius bar, but maybe someone else out there has seen this and solved the mystery?
    Cheers...

    FYI, uninstalling Parallels and VMWare's Fusion (I was using both) doesn't help.
    However another scrub of the System log did reveal something peculiar. Sort of a mess to post but in case anyone from Apple is watching this, I am attaching. This is coming up right after I resume wake from suspend.

  • Mighty Mouse and wireless keyboard stop working

    Just got my iMac yesterday and everything worked out of the box. But once yesterday and once so far today, the wireless mighty mouse and keyboard stopped working.
    Today I noticed after the mouse stopped moving the cursor, the little green light on the bottom of the mouse was blinking. I turned off the mouse and turned it back on, but the green light still blinked and the mouse still didn't work.
    The only thing that did something was the power button on the iMac. I had to turn off the iMac and turn it back on. Then the keyboard and mouse worked again.
    What's going on? Do I need to get the iMac repaired?

    Hello and Welcome to Apple Discussions ...
    Try deleting this file. com.apple.bluetooth.plist
    /Users/YourName/Library/Preferences. Drag that file from the Preferences folder to the Trash, empty the Trash and reboot.
    If that doesn't help, make sure the batteries are charged. Go to System Preferences/Keyboard&Mouse. Click the Bluetooth tab. Your battery levels are displayed there. When it gets down to one green bar on the left, install new batteries.
    If none of the above helps, turn the mouse and keyboard off. Delete the mouse and keyboard from the System Preferences/Bluetooth devices window. Select the mouse in the window on the left, then click the minus - button. Now open the slider on the mouse so the green light blinks. Click + which will launch the Bluetooth Setup Assistant. Just follow the instructions. Same for the keyboard. If you still have issues with the wireless hardware, I'd take it back. You have 14 days in case you need to replace the iMac.

  • U530 Touch Keyboard stops working after a period of time

    I just got a new Ideapad U530 touchscreen laptop yesterday.  After a few minutes the keyboard stops working.  I uninstalled a few of the Lenovo multimedia programs I don't need.  Is there a bios update or a driver I should update after purchase?
    Moderator Note; subject edited
    Solved!
    Go to Solution.

    The reset didn't work partially.  I reinstalled the Comodo firewall and the keyboard stopped working again.  I uninstalled it and installed the free Zonealarm.

  • After upgrade my MBP from snow leopard to mountain lion all my smb connections stop to work.

    After upgrade my MBP from snow leopard to mountain lion all my smb connections stop to work.
    Now iám using mac os 10.8.2
    I can see the server, I can choose the drive, but when try to open a folder the message on Finder is: You don't have permissions to see the content.
    I already delete the key and try to connect again, but the problem persist. Already try change the ip from file server. Already try differents users. (admin, guest, etc...)
    I have a windows server 2008 and a NAS working with SMB protocol. Both with the same problem.
    That problem occurs only on Finder, if I try see the folder by Terminal, is possible to see my files.
    Any Solution ?
    Any Tip ?
    Any Question ?

    Not knowing how much RAM is installed in your iMac, your iMac can take a total of 8 GBs of RAM.
    Before upgrading to Mountain Lion, I would strongly suggest installing the maximum 8 GBs of RAM.
    Correct and reliable Mac RAM can be purchased from online Mac RAM sources Crucial memory or OWC (macsales.com).
    Here is OWC's link to your model iMac and the RAM modules you will need.macsales
    http://eshop.macsales.com/item/Other%20World%20Computing/8566DDR3S8GP/
    You can purchase and download OS X 10.8 Mountain Lion from the Mac App Store in the OS X dock.
    Before installing, it would be prudent to make a backup copy of all of your important data or your entire current system. Either using, optical discs, USB flash drives or external hard drives.
    This is too insure protection of your data in case something goes wrong with the install of OS X Mountain Lion.
    Good Luck!

  • I have a MacBook Pro with Snow Leopard. After connecting my HP Photosmart D110 to it, the printer works but the scanner doesn't. The message is"The scan cannot be performed because another program has control of the HP imaging device". Can anyone help?

    Found the answer on the HP site. It's the original software that works with this printer OS X 10.6!!

  • I have a MacBook pro version 10.6.7 with snow leopard. After an scheduled software upgrade I could not open Quicken (It said it could not open the files). Now I can only open it if I have my external drive on. Can you help?

    All the information that I had input on Quicken is gone. I have to have the external hard drive that I use to back up to be able to use quicken now. It is as if it was erased from the laptop hardrive

    Try repairing permissions. My favorite way is with a utility called AppleJack. Info and download here. It's free. It only works when you boot in Single User Mode. When restarting or booting, hold down the Command key and S keys.
    You will get a very different startup screen that looks like the Terminal app has hijacked the screen. Just let the lines of text scroll by. When that happens you will get a text entry prompt. Type in "AppleJack" without the quotation marks.
    A DOS looking menu will appear. Choose 1 or d to run Disk Repair. If you get a message that Disk Repair found and corrected errors, run it again. Repeat until you get the "your disk appears to be ok" message. This rarely happens with my experience, though. This does the same thing as as booting from an external drive and running Disk Utility's repair. Only, no external drive is required!
    Next, choose 2 or p to repair disk permissions. This will take a little while. AppleJack warns that it will take up to an half hour to run repair permissions. It'n never taken more than about ten minutes for my MacBook Pro.
    As permissions are repaired, you will see each repair scroll on the screen. When done, the menu returns, choose q to quit. Then at the prompt, enter "exit" without the quotes. Your MacBook Pro should restart into Mac OS normally after this.
    Hope this helps.

  • My macbook mouse/touchpad has stopped working. After 5 minutes ,the mouse won't click and I have to shut down. What's wrong?

    I have a white macbook, about 4 years old. Every time I use it, after five minutes, the mouse and touchpad stop working. You can still hear the click but it doesn't actually click anything on the screen, effectively freezing the computer. I have to just shut it down. What can i do about this?!? Thanks

    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    The purpose of this exercise is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login. Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. The instructions provided by Apple are as follows:
    Be sure your Mac is shut down.
    Press the power button.
    Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
    Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
    Note: If FileVault is enabled under Mac OS X 10.7 or later, you can’t boot in safe mode.
    Safe mode is much slower to boot 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 your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    Test while in safe mode. Same problem(s)?
    After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.
