Crash to Login Screen - typical?

That's not a kernel panic, it's a crash of the WindowServer process, which ends your login session. Please post the whole crash log.

That log isn't very revealing. If this has only happened once, I frankly don't think it's worth pursuing. If it becomes a recurring problem, then you can start trying to troubleshoot it, but that's very difficult when the crash isn't reproducible.

Hi Linc,

Just leaving a note here to say that it does happen occasionally but without a clear cause. The only thing that is consistent is the source being CGXUpdateScoreboard. I just posted some info in another thread before finding this one:

https://discussions.apple.com/thread/3118017?answerId=15641907022#15641907022

I had a similar problem, which I posted a thread about, with no real response. Apple suggested reinstalling everything, which I did, and the problem went away for a while, but now it's back. If anyone has any suggestions, I'd very much like to hear them.

No one but you seems to be reporting this crash. Have you tried to reproduce it in safe mode?

Not true, there are at least four other discussions about what seems to be the same problem, three of which were opened quite recently. Recreating in Safe Mode isn't really an option,this doesn't happen on a regular basis. If I could find a common action that I was taking when the crash happened, it would be much easier to figure out what the problem is.

Same here. I have been looking for possible triggers. There is no common cause. The only thing I initially found was that running iTunes seemed to trigger it more. Stopped using iTunes and switched to VLC. Happened less but still did. Stopped using VLX, and it still happens but apparently less. What could be causing it now? I don't know.

This is the joy of computing! 🙂 If I could reproduce it I would jump right into safe mode to confirm. But since it's my workstation with deadlines due and it isn't stopping all work, just sporadically, I don't have time to investigate it. I certainly will try when things lighten up a bit if it's still occuring, and I haven't upgraded to 10.7. 🙂

Launch the Terminal application, copy or drag -- do not type -- the line of text below into the window, and press return:

kextstat -kl | awk ' !/apple/ { print $6 } '

Post the lines of output (if any) that appear below what you just entered (the text, please, not a screenshot.)

Next, do the same thing with this line:

sudo launchctl list | sed 1d | awk ' !/0x|apple|com\.vix|edu\.|org\./ { print $3 } '

That's one line, not two. You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. You don't need to post the warning.

Next, this command:

launchctl list | sed 1d | awk ' !/0x|apple|edu\.|org\./ { print $3 } '

Again, one line. Finally, one more:

ls -1 /Library/{InputManagers,StartupItems}

Remember, this is all drag-and-drop or copy-and-paste, whichever you prefer -- no typing, except your password.

You can then quit Terminal.

Start by completely purging your system of all Norton or Symantec products. If that doesn't solve the problem, post back.

Did a clean install of Snow Leopard, followed by an upgrade to Lion. Still happening.

Have you reinstalled any of your third-party system modifications? If not, you're dealing either with a hardware fault or an OS bug.
