Write bits inexplicable changed in /home
Here's a puzzle:
All my files in my home directory somehow suddenly lost their w attribute, ie became ro. The execute and read bits were not affected, and the filesystem was still mounted rw. They looked like -rw-r--r-- I was not running X as root, never do. The user and group ownership were unchanged.
I was running KDE and first noticed it when I tried downloading a file and could only copy it to my Desktop, not my downloads in /home/me. I also had an open file in Kwrite which couldn't save. I had removed lesstif and added openMotif. Root's account seems to be the same, but I'm not sure the permissions weren't always that way.
I shutdown, ran fsck from init 1, looked at smartctl and there were no errors. Of course I couldn't run init 4 or startx from init 3, because no .Xauthority could be written, nor any .serverauthority.
So I typed chmod a+w *, and everything seems to be ok again.
What could account for that, and what else might have been affected?
