ls output not compact anymore

I wanted to ask about the ls command in lubuntu 15.10. Now there is a new line for every entry. I know from other distributions that there is also an output style where ls outputs the content of folders without new lines in a compact way when typed without any options. Is that possible in lubuntu, too?

Edit:

The ls version is 8.23 and type ls outputs

ls is aliased to `ls --color=auto'

The -C flag does not create a different output than without any options.

I have read the manual man ls after the comment, but could not find anything relevant to my question there.
