I messed up good this time. I am running FC3, and I was setting up a new user, copying files from my home directory to use as a basis for the new user. I was doing this as root in the new user's home directory. I must have been in the wrong directory as root when using chmod/chown, because when I logged out of the new user's session and went back to mine, I was told that the session lasted less than 10 seconds, and that was as far as I got.
The details available in that window said there were no permissions available for some files in .gnome. That is all I recall.
As root, in another user's session, I did a chmod -R 777 for my entire home directory, then I got an error in gnome that the database for locking files did not exist. Another log-out/in seemed to solve that.
It appears that I am now back to where I was, but things are a tad funny. For one thing, the user's photos at the log-in screen are gone. They were in my home directory....and they are still there. I can solve that, but.....my question is, do I need to worry that some owner/persission settings for all files are not as they were? If so, where can I go to find what they should be?
Thanks in advance from a dangerous typist.
