A GTK3 GUI interface for Redshift
would be amazing.
One already exists in the form of RedShiftGUI, but it's extremely buggy, and hasn't been updated since 2010. Maybe someone could fork it?
If anyone is starting from scratch, I would recommend trying to copy the functionality of the superb Redshift KDE Plasmoid, which allows you to change brightness and color temperature on the fly by placing the mouse cursor over the icon in the taskbar, then spinning the mousewheel.
Cheers for wanting to help in such a way! :)
As for ideas;
Redshift (an app that reduces blue light to relieve eyestrain and insomnia) could really use a good GUI control panel for GTK-based DE's. The only one available is redshiftgui, which isn't practically usable due to being incredibly buggy, and has been abandoned for 4 years.
In contrast, KDE has a fantastic Plasmoid add-on which allows fine-grain control over redshift from the taskbar. However, it is only compatible with KDE.
A new Redshift GUI usable with GTK DE's, or even new maintainership of redshiftgui to iron out the bugs, would be greatly appreciated if that's something you'd be interested in. :D
so no one has mentioned RedShiftGui [https://github.com/maoserr/redshiftgui/downloads]. A very nifty GUI which lets you control both redness and darkness; very useful for manually tweaking the settings according to the environment you're in. The gnome indicator is very basic in functionality. Have been using it for two years - very handy. Although not actively developed.
Open source alternative(better than f.lux if you're using linux): https://github.com/maoserr/redshiftgui/downloads
f.lux is great for Windows. But fluxgui for Linux is not that great and doesn't integrate well outside GNOME. Redshift is a better option for Linux as it works well with KDE/GNOME/X and is open-source (available at all major repositories)
Nope, I've never seen that error before.. it almost looks like something has corrupted itself, really bizarre. I have to say though it's not my code :) I got it mostly from https://github.com/maoserr/redshiftgui with just some minor changes and GTK3 instead of GTK2 (which looks awful).
I may have a solution for the hibernation problems, via TuxOnIce. I've also found a BFS patch that works with 4.4, basically the patches from pf-kernel, albeit I could not get the "commits" (for UKSM and Tux) in the GitHub to patch cleanly so instead had to download the last official versions. It's untested so far though, and I need to integrate my modified RedshiftGUI, which is in my opinion much better than redshift-gtk and can be disabled by default (modifications are to make save/reload work, to continually check the screen brightness level, to work with GTK3 as it wouldn't compile and the dialog looked awful otherwise, and not to statically link libraries).
