I find the atril pdf viewer to be the most satisfactory choice for my needs. However, a problem is that it does not save my configuration.
More specifically, I go to its View menu and set my desired configuration. Then I go to Edit, Save Current Settings as Default. It has no effect, and atril opens with other values. I should note that I don't run any desktop environment, not Mate or any other. None of the files in /usr/bin or in /usr/share/atril appear to specify configuration values. My guess is that atril would look for a file such as /usr/share/atril/atril-config.xml or ~/.atril in which configuration values are set. Haines Brown
