Akonadi is started unwillingly

[Ganton]

Recently, Akonadi starts automatically when Kubuntu 23.10 starts, wasting RAM space, CPU cycles, battery life, etc. when it's not used. This didn't happen before, Kubuntu worked without needing Akonadi. In /var/log/syslog we can see, for example:
    kalendarac[2398]: org.kde.pim.akonadiserver: Running DB initializer

There's more information on:
- https://unix.stackexchange.com/questions/725548/kde-plasma-prevent-akonadi-stuff-from-being-launched-at-startup
- (a good solution is offered there:) https://discussion.fedoraproject.org/t/how-can-i-disable-calendar-reminders/75984
- (more cases:) https://www.reddit.com/r/kde/comments/vp4bam/why_is_calendar_reminders_using_270_mb_or_ram_on/

And thanks for the good work of Kubuntu, by the way!

I am not seeing /etc/xdg/autostart/kalendarac in 24.04 testing so perhaps it was fixed? Can you confirm this is still an issue.

[Ganton (ganton)]

Thanks, Scarlett. The problem was not detected using today's "Kubuntu 24.04 (Noble Numbat) Daily Build":

$ sudo grep -i akonad /var/log/syslog
$ sudo grep -i kalend /var/log/syslog
$ ls /etc/xdg/autostart/*kal*
ls: cannot access '/etc/xdg/autostart/*kal*': No such file or directory
$ ps aux | grep -i [a]konad
$ akonadictl status
Command 'akonadictl' not found, but can be installed with:
sudo apt install akonadi-server
$ dpkg -l | grep -i akonadi
