Position of the icons on the desktop not stored
If one day all your icons are always on the left side of the desktop and their position is not remembered between the sessions: check the permissions and make a correct setting:
$ find . '!' -user $USER and look if "./.local/share/gvfs-metadata/home" is present into the list of files not owned by you $ ls -al ./.local/share/gvfs-metadata/home will show who is the owner (generally this is "root") $ sudo chown -R your_user_name:the_group .local/share/gvfs-metadata/home
Logout and re-login: the problem should be gone.
