Cinnamon, dbus, and the slideshow scripts

[Altreus]

Hihi

I've been working on some scripts for my slideshow because I have an image dump and I'd like to throw away wallpapers that suck. I also like the option I have on Windows 10 of being able to right-click the desktop and just skip to the next image. This is good if it randomly picks the same images in short order without giving the rest a fair shake.

So I have one script called `wp-sucks` and another called `wp-next`. (Please use these if you want them)

Code: Select all

#!/bin/bash
# wp-sucks

WP=$(gsettings get org.cinnamon.desktop.background picture-uri | tr -d \')

rm ${WP/file:\/\//}

wp-next

Code: Select all

#!/bin/bash
#wp-next

WPPATH=$(
    gsettings get org.cinnamon.desktop.background.slideshow image-source \
    | tr -d \'
)

WPPATH=${WPPATH/directory:\/\//}
WP=$( shuf -n 1 <(command ls -1 $WPPATH) )
gsettings set org.cinnamon.desktop.background picture-uri file://$WPPATH/$WP
gsettings set org.cinnamon.desktop.background.slideshow slideshow-enabled true

So the weird thing is this last line, because if I set the picture-uri manually it disables the slideshow, so I have to turn it back on again. But it seems like this sometimes gets stuck and it's hard to reproduce this problem (although this might have been testing issues).

My question is, is there a better way of asking the slideshow to advance now? Can I poke whatever internal timer is running to get it to trigger immediately?

As a follow-up to my previous post, I have also noticed that if I use gsettings to change the directory the wallpapers are drawn from, the slideshow stalls, even if I reactivate it. They don't start again until I go into the wallpaper settings GUI and turn the slideshow off and on again.

I appreciate you looking at my question but this link is about slide shows in LibreOffice Impress, not the Cinnamon desktop wallpaper slideshow.

I've discovered that I can trigger the next image by toggling the flag that enables the slideshow in the first place

Code: Select all

#!/bin/bash

gsettings set org.cinnamon.desktop.background.slideshow slideshow-enabled false
sleep 1
gsettings set org.cinnamon.desktop.background.slideshow slideshow-enabled true

This seems to require the sleep and causes my laptop to try to take off while it does the change. It doesn't seem to get quite so warm when changing normally. It also seems like a hack and a half.
