Public bug reported:
I had not changed the permissions for any files in my home folder.
However, two recent upgrades have changed critical permissions that allow me to
log in, probably for .Xauthority, .dmrc and/or .bashrc.
The result was that twice, when I re-booted after an upgrade, my logon screen
led me to a blank wallpaper with nothing working.
(Logging in as a guest was fine.)
When I got in through a rescue disk and attempted to copy files to a thumb
drive, I discovered that random of my user-created /home/name subfiles had been
assigned permissions that did not allow me to access them.
???
Anyway, I tried various CTL-ALT-1 fixes to re-set permissions from the Ubuntu
web site. I tried changing the owner / permissions for just /home/ then just
/home/name then a couple of suggestions that put the settings into "default"
mode, including changing all /home/name dot-something folders to user +rwx.
Nothing worked.
Finally I just changed the entire /home/user folder to my ownership, +rwx
recursively, and that worked.
