redshift failing to adjust color

After a recent package update, redshift fails to adjust the color of my screen.

I am using the Dell XPS 13, 2015 edition.

Running redshift -v produces the following output:

$ redshift -v
Location: 32.10 N, 85.60 W
Temperatures: 5700K at day, 3500K at night
Solar elevations: day above 3.0, night below -6.0
Brightness: 1.00:1.00
Gamma (Daytime): 0.800, 0.700, 0.800
Gamma (Night): 0.800, 0.700, 0.800
Status: Enabled
Period: Night
Color temperature: 3500K
Brightness: 1.00

but my screen doesn't change color.

The same thing happens when I try to use drm.

Specifying vidmode:

$ redshift -vm vidmode
Location: 32.10 N, 85.60 W
Temperatures: 5700K at day, 3500K at night
Solar elevations: day above 3.0, night below -6.0
Brightness: 1.00:1.00
Gamma (Daytime): 0.800, 0.700, 0.800
Gamma (Night): 0.800, 0.700, 0.800
Gamma ramp size too small: 0
Failed to start adjustment method vidmode.

Here is my redshift.conf:

[redshift]
temp-day=5700
temp-night=3500

transition=0

gamma=0.8:0.7:0.8

location-provider=manual

adjustment-method=randr

[manual]
lat=32.1
lon=-85.6

[nschoem@X-ME56-Nesasio ~]$ grep -ve '; ' .config/redshift.conf 
[redshift]
temp-day=5700
temp-night=3500

transition=0

;brightness=0.9
;brightness-day=0.7
;brightness-night=0.4
;gamma=0.8
gamma=0.8:0.7:0.8

location-provider=manual

adjustment-method=randr

[manual]
lat=32.1
lon=-85.6

This problem started occurring after a receng upgrade to the latest GNOME packages.  Redshift works as intended on xfce.

How do I get redshift working again under the latest version of GNOME?  Is a rollback my only option?

Run GNOME under Xorg rather than Wayland. Then redshift will work again.

Re: redshift failing to adjust color

Confirmed: redshift works properly in GNOME on Xorg.  Thank you!
