From your logs it appears you have a few "Permission denied" errors on files within your home directory. This can happen easily as a consequence of running some things as root in a previous session.
To fix this, please log into a VT (or MATE or Cinnamon) and run:
sudo chown -R $USER ~
or more specifically:
sudo chown -R username /home/username
That should fix your "Permission denied" errors, and possibly this whole bug.
