Just to clarify some confusions, here is a description about the currently available wallpapers within Audax repository:
deb https://techtimejourney.net/audax-initial/ audax main
audax-labeled (A labeled version of Audax wallpapers. The current 0.2. default)
audax-wallpapers (The old default wallpaper set, which contains no integrated shortkeys, like audax-labeled)
calmwaters-wallpapers (An extra wallpaper set, which is also label free.)
You can install all wallpapers by doing the following within a terminal client:
sudo apt-get update
sudo apt-get install calmwaters-wallpapers audax-labeled audax-wallpapers
Alternatively, you could also use Synaptic package manager (By pressing Windows+m or gksudo synaptic)
Audax-.labeled will have all wallpapers within /usr/share/audax-labeled directory.
Audax-wallpapers and calmwaters wallpapers will have all wallpapers within /usr/share/audax-wallpapers directory.
Tip. If you use two or more displays you might want to consider installing calmwaters-wallpapers or audax-wallpapers in order to get entirely label free backgrounds. If you do wish to keep using the audax-labeled wallpapers then consider adjusting your screen configuration to become vertical. With vertical settings you could possibly (but not always) avoid wallpaper stretching issues.
