From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

ofc you may schedule it with cron but following script I wrote won't change anything. The setting is set but nothing changes. I'm on Fedora Silverblue

edit:

solution

wallpath=/usr/local/share/backgrounds/Dynamic_Wallpapers
image=$(find $wallpath -name "*.xml" | grep -E xml | sort -R | tail -1)
image="file:///$image"
echo $image

gsettings set org.gnome.desktop.background picture-uri "$image"
gsettings set org.gnome.desktop.background picture-uri-dark "$image"

and crontab

@daily ~/wallpaper_changer.sh
@reboot ~/wallpaper_changer.sh

I'm not sure about using xml files, but there's also a 'picture-uri-dark' key you need to set instead if you're using dark mode. I have a similar setup with a systemd user timer that runs every 5 minutes.

Edit: I just tried it out in the terminal and it works ok for xml files, too. Also, I try to avoid parsing the output of ls in scripts. You can use find instead, something like

find $wallpath -name '*.xml'

should work.

Plot twist: OP uses KDE

Nice one

I use a while true approach with sleep 24h or whatever. Doesn't seem to impact my CPU usage, but I guess the crontab approach is more Unix-like.

Are ypu dead set on using xml or did you want to try a Wallpaper app like Variety?

[–] [email protected] 2 points 10 months ago

Dynamic wallpapers are cool

This might work.
