Best way to run on two separate X screens?

[mrj]

Question: Is the correct way to have redshift-gtk run on two monitors which are set as separate X screens (:0.0 and :0.1) to run it twice, prefixing each run command with DISPLAY=:0.0 or DISPLAY=:0.1?

The monitors are on separate randr lists.

If you use the randr driver it should affect all screens unless you explicitly ask it to only affect one screen.

Thank you. I tried -m randr, but it only changed screen 0. However -m randr:screen=1 did target the other screen. I'll need to merge #81 to be able to use screen=all.

Yes, you are right. The randr driver can only affect one screen at a time, it will try to affect all CRTCs connected to a screen though. Did you try #81 yourself? I think that pull request only changes which CRTCs will be affected, not which screens.
