Redshift: Redshift shows no effect under Xfce

[sidamos]

Without logging any errors, the adjustment of Redshift 1.11 has no visible effect when running under Xfce.

On the same machine, with the same xorg.conf, it has visible effect (is working fine) under KDE 4 and 5.

I tried without "-m" and with "-m vidmode" and "-m randr".

I also tried switching compositing off.

I am using the Nvidia binary driver.

This is the output of "redshift -v":

Do you use the ForceFullCompositionPipeline Metamode option in your /etc/x11/* configs? Enabling this for both monitors seems to break Redshift with newer nvidia drivers/xorg servers. I'm trying to find out why this happens, as it's annoying but so far I've found no solution other than not setting the MetaMode option.

[OskarCarl]

Okay, I can definitely say that not setting "ForceFullCompositionPipeline" in the xorg configs solves this probem. I don't know what causes it, as enabling the option in the Nvidia X Server settings after logging in works fine.
Setting this on only one monitor breaks redshift on that one, but the other one works fine.
This is not restricted to xfce though, as I get the same behavior in Cinnamon.
I'm on Arch Linux with a GTX 760, dual monitors, completely up-to-date. Versions are:
nvidia-378.13-2
xorg-server-1.19.2-1

I am using { ForceCompositionPipeline = On } in xorg.conf (so, not "Full", but similar) to prevent screen tearing under Xfce.

But even with this option in xorg.conf, Redshift still works fine under KDE 5.

[sidamos]

When I switch with CTRL-ALT-F8 to the other local session and back with CTRL-ALT-F7, then Redshift works.

Can confirm: ForceCompositionPipeline disables Redshift with Nvidia binary driver.

After using Nvidia binary driver for few months without ForceCompositionPipeline, I had to enable it because sometimes some windows in GNOME would flicker. Settin ForceCompositionPipeline=On fixed that... but now Redshift doesn't work.

Ok, this seems be related to the nVidia binary driver and ForceFullCompositionPipeline. Please keep posting if a workaround is found.

I seem to have found a workaround, where if you make a .desktop file in your "~/.config/autostart" folder, then edit its properties and set the command as:

nvidia-settings --assign CurrentMetaMode="nvidia-auto-select +0+0 { ForceFullCompositionPipeline = On }"

it will allow Redshift to work with _ForceFullCompositionPipeline_, and it will be enabled on login.

Alternatively, on XFCE, you can do this through Session and Startup -> Application Autostart, and add an item with the _command_ field having the code shown above. Hope this helps.

Under aarch64 4.19.89-1-MANJARO-ARM Xfce, redshift is not working either.
