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." and quit. Version-Release number of selected component (if applicable): xorg-x11-server-Xorg-1.19.1-1.fc25.x86_64 How reproducible: Always Steps to Reproduce: 1. start gnome on xorg 2. launch xflux 3. Actual results: xflux can not run: Found 1 screen. Sorry, we only support 8 and 10-bit displays right now. Expected results: xflux runs without problems Additional info: 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: https://justgetflux.com/linux.html 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.
The nice to read this valuable topic post. https://www.stupidblogger.com/how-write-seo-friendly-articles.html
