[SOLVED] KDE Plasma "set date and time automatically" greyed (inactive)

Adjust Date and time - set date and time automatically check box is inactive in KDE Plasma 5.19.5

Artix OpenRC
rc (OpenRC) 0.42.1 (Artix Linux)
Kernel Version 5.8.6-artix1-1

I can still change the time with hwclock config file and the time works correctly, but it takes no effect on the set date and time automatically check box anyway.

I installed Artix from base: artix-base-openrc-20200214-x86_64.iso NOT the ISO with plasma (artix-plasma-openrc-20200210-x86_64.iso). And after the clean installation i installed xorg, SDDM and KDE Plasma packages.

On Arch wiki in Network Time Protocol daemon - https://wiki.archlinux.org/index.php/Network_Time_Protocol_daemon is said that:
"KDE can use NTP (ntp must be installed) by right clicking the clock and selecting Adjust date/time. However, this requires the ntp daemon to be disabled before configuring KDE to use NTP". But is there any possibility how to fix it now?


Thank you
MatMac

I've been looking at it, and the solution is not simple, KDE need ntpdate (which we have in the system), but then it can't recognize it for some reason.
This is written on the KDE man page:

Quote
If you check Set date and time automatically this module will use systemd to fetch date and time.
On a computer without systemd the NTP utilities rdate or ntpdate are used. If these utilities are missing please install them.
When you log in to the Plasma™ session while being online or when you later connect to the Internet the access to one or more NTP servers happens.

Anyway, a better solution than this is to install ntp and ntp-openrc/runit/s6 and add the time synchronization service as startup service (rc-update add ntp-client default).

Simple, KDE-independent and functional solution...

Thank you for the quick answer alium.

This is not a big deal since it is possible to update the time with the config files.

Anyway when I'm trying to start the NTP service manually i get this error:

Code: [Select]

This is a bit off topic but I'm curious how the ntp works.

To see what "services" are included in package run:
Code: [Select]
$ pacman -Ql ntp-openrc
ntp-openrc /etc/
ntp-openrc /etc/conf.d/
ntp-openrc /etc/conf.d/ntp-client
ntp-openrc /etc/conf.d/ntpd
ntp-openrc /etc/conf.d/sntp
ntp-openrc /etc/init.d/
ntp-openrc /etc/init.d/ntp-client
ntp-openrc /etc/init.d/ntpd
ntp-openrc /etc/init.d/sntp

From this list you can see 3 services (init.d) with respective config files (conf.d):
  • ntp-client
  • ntpd
  • sntp

you probably wish to start ntpd:
Code: [Select]
rc-service ntpd start

as wrote SGOrava...

I use 'ntp-client' and 'networkmanager-dispatcher-ntp-client' from our universe repo (networkmanager-dispatcher-ntp-client re-start ntp-client, if i will have internet access)

OK, thank you guys. I installed the NTP with "pacman -S ntp-openrc" instead of "pacman -S ntp" and it works well.

So, if I have installed the "artix-plasma-openrc-20200210-x86_64.iso" would I get the same issue with "set date and time automatically" check box?

Yes. you must just install ntp and his service again

since Plasma 5.20 is this option (feature) available again!
