Freeze on logout

I am not a super technical guy, but I know the basics. I am having the same issue and I was able to trace it to leaving the computer on. I only have the issue when I leave my MacBook Pro on for days. If I turn the computer off at the end of the day I have no issues throughout the day logging in and out of user accounts. If I leave the computer on overnight, I can't switch accounts if my wife left it logged into her profile. Maybe it is something to do with power and sleep settings?

I have one of the last 17" iMacs running 10.5.8. Just recently it began freezing on logout. Everything seems to go normally except the login window never comes up and I have to do a forced reboot.
Hi all,
I have the symptoms of some computers "hanging" after logout, with a black screen and a small white rectangle at the top left corner. The login window never appears. And this happens with both my admin account and a normal, non-admin user account.
I've seen this crop up recently on several user's Mac Pro's in my group. We are all running 10.6.8, and this just started happening after I installed some application updates (Microsoft Office 14.3.2, Acrobat Pro 9.5.3, 9.5.3), and some updates for the pesky little plugins such as Silverlight and Adobe Flash. I'm suspicious that this is a result of one of these updates, but a systematic approach to testing each in turn failed to yield the symptoms.
Luckily for me, in my network environment, I am set up to be able to ssh into any of these machines. When I do so on an afflicted machine, I noticed that about 8-10 processes belonging to the user account who just logged out are still active on the computer. This indicates to me that the log out process is not completing properly.
Fortunately for me, and perhaps for some/all of you here, I stumbled across a solution that "repairs" this symptom - every time so far. I just completed it again, on my 4th computer afflicted with this.
Remember that often maligned feature available in Disk Utility, that many have said does nothing useful, called "Repair Disk Permissions"? I myself have not seen this to be a very useful feature! Well, guess what - in this instance it appears to be the silver bullet that has fixed my problems simply, on each of the afflicted computers I've had.
Solution:
- shutdown/reboot the afflicted computer, by ssh & "sudo shutdown -r now", or a hard power off using the button
- when the login window appears, log in to an administrative account
- launch the Disk Utility (/Applications/Utility/ directory)
- select the boot volume in the left side of window
- click on the "First Aid" tab
- click the "Repair Disk Permissions" button at bottom left (ish)
- when the process finishes, quit the DIsk Utility
- the logout process then should work normally, if your issue is the same as mine
note: the details in the solution posted here are intended for those who may not yet know where these items are - there is no intention to suggest that anyone in this thread would not understand the instruction to run the Repair Disk Permissions..... 😉
cheers, and hope this helps,
Roy
