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.

Kubuntu Night Control does not automatically change always (self.linux)

Yeah, so I have a notebook with Kubuntu 24.04.
I have Night Control setup for warmer color 8:00PM-8:00AM

Oftentimes I go to the computer to do something and I see it is in the wrong mode. I’ve not seen any pattern it’s just arbitrarily not switching over.

My lid close action is just turn off screen; no sleep mode (problems). So usually I am opening the lid and start to use the machine and then notice this.

Is this a known issue? Or does anyone else have this problem?

I have had this happen to me when my monitor turns off before the night shift starts and when I come back let's say an hour later and the night shift is not on.

Prob has something to do with the monitor being off at the switching time

Yeah I mean that makes sense based on the observed behavior but it doesn’t make sense that it should do that. What could cause such an issue? The screen being off has nothing to do with the instructions the graphics controller is given or sends to the screen.

Maybe I’ll submit a bug report.
