[Cinnamon] Redshift disappears from the notification area after suspend

[ThePhi]

Hello!
I have used Redshift for years without problems.
Recently (a few weeks ago maybe) the icon in the notification area disappeared after waking up from suspend.
The program is still running though as I can see in the system monitor: I see "Redshift" and "Redshift-gtk".
I force-close them and restart Redshift (by clicking on the shortcut in the launcher) and it reappears in the notification area.
Note that after a restart the icon appears normally in the notification area though.

Thank you!

What shall we answer, if we do not even know the version of Mint and the desktop?

[ThePhi]

Ok, sorry:
Linux Mint 21, Desktop environment: Cinnamon 5.4

Open Users & Groups and create a new account. Log out and into the new account. Same problem there?

[ThePhi]

You mean to log out from my account when it disappears and switch to another account?
I did that and actually, the Redshift icon reappears again. But it's not very practical since I lose my session...

You understood me right. This was only a step for investigating. It tells us, that your problem is in your account.

Next steps:
For investigating the culprit in your main account:

Open the file manager and make hidden files visible (ctrl-h).

#1 Delete the hidden folder .cache. Log out and back in and check.

The folder gets automatically recreated.

#2 If this does not help rename the folder .config to .config.renamed. Log out / in.
Very most of your settings will get lost, but you can get them back, by renaming to the original name.

Also here a new folder with default content gets created. If you later want to get back, delete this folder and rename the original folder back. Out / In.

#3 The same as #2 with .local.

i would add the Cinnamon applet to your panel. Redshift has one that works really well with cinnamon and gives you control over redshift without having to modify text files. Right click on a blank spot on the panel select applets look for redshift, If you don't see it go to the download tab and download it then back to Mange and add it to the panel. Works great here.
Good luck.

Even if I don't do any of these 3 steps, simply by logging out and in, with the SAME account, the Redshift icon reappears.

Thank you, I didn't know it existed. It lacks the options to set your own dawn and dusk time though so it can't fit me: I go to sleep very early and get up also very early in the morning (4am usually) so I need the option to set Redshift accordingly.

Well one way around that is that you can find a time zone that would fit your schedule and use the Lat and Long coordinates to that time zone.
Just a suggestion.

Thanks, but my usual night length is 6 hours so changing timezone won't solve it...
