I have a script for changing wallpapers that I have run before with crontab. Did a new install yesterday and can't get crontab to work. I have searched for and not find any logs from crontab but it doesn't work, here is the output from crontab -l
bola@bola-pc:~$ crontab -l
# Edit this file to introduce tasks to be run by cron.
#
# Each task to run has to be defined through a single line
# indicating with different fields when the task will be run
# and what command to run for the task
#
# To define the time you can provide concrete values for
# minute (m), hour (h), day of month (dom), month (mon),
# and day of week (dow) or use '*' in these fields (for 'any').#
# Notice that tasks will be started based on the cron's system
# daemon's notion of time and timezones.
#
# Output of the crontab jobs (including errors) is sent through
# email to the user the crontab file belongs to (unless redirected).
#
# For example, you can run a backup of all your user accounts
# at 5 a.m every week with:
# 0 5 * * 1 tar -zcf /var/backups/home.tgz /home/
#
# For more information see the manual pages of crontab(5) and cron(
#
# m h dom mon dow command
*/2 * * * * /usr/bin/backdrop-randomizer R
#
bola@bola-pc:~$
I have tried with or without the last # in the crontab file
When I do the command/run the script manually the walpaper changed as it shall do. backdrop-randomizer R
Edit : Looks like cron is not working
bola@bola-pc:~$ systemctl status cron
● cron.service - Regular background program processing daemon
Loaded: loaded (/lib/systemd/system/cron.service; disabled; vendor preset: en

Now I have to find out how to start it ....
-
# systemctl start cron.service
and permanent# systemctl enable cron.service

# systemctl start cron.service
and permanent# systemctl enable cron.service

Thank you unklarer, I did search internet for starting cron with systemd, didn't find it, I just found the maybe old way do do it and got it working?
# service cron start
# update-rc.d cron enable
+
so it's running now, shall I change to the systemd way?
As I understand there is a sytemd way instead of using cron to run a script on scheduled times but I can't find anywhere how to do it, not that I understand anyway.

There are many ways to Rome. ;)
About a year ago I tried this in kde. (https://forums.mageia.org/de/viewtopic.php?f=8&t=3007) It didn't work there. The package feh must be installed.
On the other hand, the same thing worked perfectly under Openbox / Fluxbox.
Maybe this will work, too: feh.sh
#!/bin/sh
DIR=~/Images/Wallpapers
# temps de rotation des images en secondes
INT="600"
while true; do
feh -q -r -z --bg-fill $DIR
sleep $INT
done
exit 0
I haven't tried it. :P

The benefit with backdrop-randomizer (https://forum.siduction.org/andomly cycles through wallpapers without repeating) is that it will "randomly cycles through wallpapers without repeating" The script first creates a random list of (in this case) wallpaper files in a specified mapp and then cycle through all of them before creating a new random list to start over again. It's made for XFCE from the beginning.

@vilde: fore the sake of mental health leave crontab alone and put a job into /etc/cron.d - thats all - the systemd way would be to use timers, should be easy, never used it :)

Hmm, I have used crontab the last year and more, maybe that's why I feel a little crazy, on the other hand Waylon sings:
I've always been crazy but it's kept me from going insane
Ok, so then I have to try to learn something new /etc/cron.d I will try fort the fun of it, or timings, I'll be back
