By photo editing, do you mean a RAW editor alternative to Lightroom? Darktable, RAWTherapee, DaVinci Resolve, AfterShot Pro, and the unhelpfully named "Art" [1] are all options for that. For something to replace Photoshop, Affinity can be made to run in Wine, and their CEO is open to the idea of a native port.
I've tried Darktable and RAWtherapee. The problem is that I'm lazy with my photo editing and since I started using DxO PhotoLab I've come to rely on its features that help me get that job done quicker than anything else.
