not by itself - the code in budgie-desktop will need to understand that when you specify an .xml file it needs to hand-off to the routines contained in the library that processes the .xml file.
Again - not really - a helper app like komorebi or wallset will be required - but this will be at the expense of desktop icon support
And Wallstreet does not allow to set a starting time ( it starts with session if I understand correctly ) and does not show pictures in sequence ( ie. sorted by their name - it’s always random ).
I really have to give up on that idea.
Stubborn me.
After installing libgnome-bg :
file:///usr/share/backgrounds/canonical-wall-12/canonical-wall-12.xml
Well there is a random tickbox on the applet settings - but you are quite correct it will display in name order I think https://github.com/UbuntuBudgie/budgie-extras/blob/20a8ab8efd49e6cc852c06afcf7d3c2db2ff50a2/budgie-wallstreet/src/wallstreet/wallstreet.vala#L182 … but if you are saying its still random then the code function there reading the filenames in the folder needs to be forced to sort - a one line change I think.
Certainly I haven’t seen anyone ask to start/stop at specific times on our budgie-extras github tracker.
Yes it’s exactly what I’m saying, it’s always random.
Yeah I guess my obsession with « clocked / synchronized » backgrounds is weird, ha, ha !
Please do raise separate issues here GitHub - UbuntuBudgie/budgie-extras: Additional Budgie Desktop enhancements for user experience
Tell me if it’s enough / if modifications are needed.
Last question - I won’t promise but I hope.
What is the default hardcoded duration of transition between two background pictures in Budgie ?
This is the number of milliseconds for the transition https://github.com/BuddiesOfBudgie/budgie-desktop/blob/195fbe146c9d16ec6b7d4535745f5b0bc143cbae/src/wm/background.vala#L34
If you turn off animations in BDS then there isn’t a transition period
