I have the same problem in Kubuntu 21.04

sicherist commented 3 years ago

Probably the same as #810

vrossum commented 3 years ago

Probably two instances running. Check with ps uax and kill one, or killall redshift-gtk and start one up again.

To the developer: redshift should have one instance max. Some programmes have that.

I have the same issue after updating to 21.04. Since Redshift hasn't had a new release in the recent years, I assume it's because of the update to Python 3.9.

I'll see if I can fix that properly. Restricting to one instance should be implemented for such a program in general, but we should also fix the root cause here.
