Dear Maintainer,
When I start nemo to control my desktop. I have icons, but there is no
wallpaper. Background stays always black.

There is some default background image configured in debian-alternatives, and
most programs respect that.
# update-alternatives --display desktop-background
 desktop-background - auto mode
   link currently points to

   Current 'best' version is
   '/usr/share/images/desktop-base/lines-wallpaper_1920x1080.svg'.
I would expect nemo to use that settings.

Besides I couldn't find any settings in nemo preferences to change that
desktop background, but it would be problem if it could use one from
update-alternatives.

Hi Emil,

thanks for the report, and sorry for the very late reply.

This is not something nemo handles: since 2013 nemo doesn't draw the
desktop background at all, its desktop window is transparent and only
shows the icons. In a Cinnamon session the background is drawn by
Cinnamon, and in Debian its default already is the desktop-base
alternative (cinnamon-core sets org.cinnamon.desktop.background
picture-uri to /usr/share/images/desktop-base/desktop-background). With
other window managers, the background has to be set by the session or by
another tool.

So I'm closing this bug, as there is nothing to change in nemo.

Best regards,
Fabio
