Hello.
I’ve set Always on night color in my KDE settings. However, every time I reboot my computer, the panel indicator(the bulb 
) says night color is on, while actually it doesn’t. I need to toggle it twice to really turn on night color.
My distro is Ubuntu 22.04 with Plasmashell 5.27.11 and x11. System Info below:
I am willing to provide more infos if you’d like!
seem to remember this being an occasional annoyance after i first installed kubutu 22.04, but are you saying you installed ubuntu and then installed plasma along side gnome?
if you type “info” on the desktop, open the setting page, copy the details and paste them here, it would help.
you should also probably upgrade to 24.04
I initially installed Ubuntu22.04 with GNOME, then I installed kubuntu-desktop package(plasma version 5.24) , and upgraded plasma to 5.27 following this instruction: Plasma 5.27 LTS for Jammy 22.04 LTS available via PPA | Kubuntu
I’ve pasted the system info screenshot onto the origin post above.
Thanks again.
dropping plasma onto of ubuntu is going to lead to disappointment… this is one of those disappointing things, i’d wager.
the maintainers over at kubuntu know how to set things up so this kind of stuff doesn’t happen.
at this point i would just recommend you install kubuntu 24.04
I figured out a not-so-elegant workaround myself.
Create a bash script toggling night color, namely enable_night_color.sh .
#!/bin/bash
/usr/bin/qdbus org.kde.kglobalaccel /component/kwin invokeShortcut "Toggle Night Color"
sleep 1
/usr/bin/qdbus org.kde.kglobalaccel /component/kwin invokeShortcut "Toggle Night Color"
Press Alt + F2, then type autostart, get into the Autostart system settings, add the shell script you’ve created as a Login Script.
Now every time on boot, the script will be automatically executed , toggling night color twice.
Just ran into this on my Kubuntu 24.04… not sure if this apt-get update made a difference:
Upgrade: packagekit-tools:amd64 (1.2.8-2ubuntu1, 1.2.8-2ubuntu1.1), gir1.2-packagekitglib-1.0:amd64 (1.2.8-2ubuntu1, 1.2.8-2ubuntu1.1), packagekit:amd64 (1.2.8-2ubuntu1, 1.2.8-2ubuntu1.1), libpackagekit-glib2-18:amd64 (1.2.8-2ubuntu1, 1.2.8-2ubuntu1.1)
I just rebooted, and Night Light started working again.
