Comment 4 for bug 1574789

I think that the committed fix has a bad side-effect:
http://launchpadlibrarian.net/257669273/ubuntu-mate-settings_16.04.5_16.04.5.1.diff.gz

Note the line that reads:
+rm_conffile /usr/share/X11/xorg.conf.d/90-zap.conf 16.04.5

This file is not a conffile and shouldn't be handled as a conffile.

Now, when upgrading to the proposed package, I got this warning:
> Obsolete conffile /usr/share/X11/xorg.conf.d/90-zap.conf has been modified by you.
> Saving as /usr/share/X11/xorg.conf.d/90-zap.conf.dpkg-bak ...

I never modified that file though, so a .dpkg-bak file shouldn't be left on my disk.

@flexiondotorg, could you please reupload without that rm_conffile line?

The 90-zap.conf file will properly get deleted by dpkg on upgrade since it's not a conffile, so there's no need to handle it specially...
