Description of problem:
I use xflux and after a recent update of xorg-x11-server-Xorg, when launching xflux, it will complain:
"Sorry, we only support 8 and 10-bit displays right now."
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. start gnome on xorg
2. launch xflux
xflux can not run:
Found 1 screen.
Sorry, we only support 8 and 10-bit displays right now.
xflux runs without problems
Downgrade to xorg-x11-server-Xorg-1.19.0-0.3.20161026.fc25.x86_64 fixed the problem.
I know nothing about X, but it *feels* like the new xorg server omitted/changed an API for application to query the display bit information.
The said xflux is available here:
It's something similar to iOS' night shift that is used to control blue light.
I just realized there is redshift in Fedora's repo which does the same thing and is still working.
