Redshift funky behavior

I run redhsift.  I have my laptop and a external monitor hooked up via HDMI.  It will switch between the red-ish color, and normal screen color.

Re: Redshift funky behavior

How fast?  When?  On which screen?  Both?  Does it happen when the external monitor isn't connected?  Logs?  Journal?  Anything?

EDIT: it seems you have a growing history on this forum of asking vague questions and being continually prompted for relevant information and being directed to the guidelines on posting logs.  Stop making it hard to help you, or no one will continue to bother.  You also have a history of abandonning your threads which is even more of a dissuasive to trying to offer help.

Re: Redshift funky behavior

And how many instances of redshift are running at this point?

Re: Redshift funky behavior

1 instance is running.
It happens on both screens.  It will stay normal color for about 3-4 seconds, then turn red-ish for 1 second, then go back, and repeat.
I don't see any logs that would be relevant to this matter in /var/log.

Re: Redshift funky behavior

Maybe your desktop has things like a gamma or color profile feature. The desktop's settings daemon and redshift might then battle with each other and try to override gamma changes from the other repeatedly.

Re: Redshift funky behavior

How would I find that out?
I am running lxde right now.

Re: Redshift funky behavior

What happens if you kill redshift, attach the second output and try to run a single adjustment ("redshift -O 4500")? Does it get reset after a while?

Re: Redshift funky behavior

Well, then something™ else manipulates the gamma ramps.
Output of

loginctl session-status

?

I don't know LXDE. I'd just go and look through its settings tool for anything that looks suspicious. It probably has something where you can configure displays for example, maybe there's a gamma setting somewhere in there.

The other idea I have is that you maybe have redshift running twice, like for example one through a systemd user service, and the other on the desktop for an icon in the tray. But I don't know if that would actually show the problem you are seeing because the two redshifts would probably use the same config file for both instances so I wouldn't understand why they would try to do different colors.

Re: Redshift funky behavior

Either xf86-video-intel-backlight-helper or autorandr-launcher sound highly suspicious - kill them both and try redshift again.
