P: Provide support for Linux

I can use my laptop or phone for most operations and lightroom CC is awesome on both, cant wait for further updates but no linux support is heart breaking. I have linux on my desktop and would love the ease of use to edit my photos without hooking my laptop up to monitor.

Can Darktable transition all my edits without any loss or visual changes? I seriously doubt it.

There are a lot of us who are forced to keep on using windows just for using Lightroom. I am a physicist who does computational physics. I have absolutely no need and no time for windows and their updates and all the rubbish that comes along with it. These days it is becoming increasingly difficult to dual boot windows and Linux and I need Linux for my work and basically everything that can be done on a computer runs on Linux other than Photoshop and Lightroom. I absolutely love photography and Lightroom is the most essential tool for me and a lot of others. It would be wonderful to have Lightroom for Linux!

I would love to be able to edit on my Linux machine. Thanks for the web support, but there should be a real client app as well.

I wouldn't create any software dependent on Adobe SDKs.  I had some fairly complex javascript programs for Bridge, but gave up when Adobe failed to fix (or even acknowledge) critical bugs for over 5 years in Bridge, although it was working under photoshop.  Here is an  example:

It's been two years. Any progress on these bugs?

Thanks for keeping the pressure on everyone.  I absolutely love my setup with MIDI2LR and a Novation Launch Control XL but the craziness of a few of these bugs certainly throws a wrench in editing 1,500 photos each week.  As MIDI controllers become more popular in editing I hope this pushes Adobe to fix the bugs.  I mean there must be a reason they want me to pay them every month right....

I think the "real" problem is not in the API but in the "trigger" of the alternate display function. For some (unknow) reason it triggers with the Click-Event on the slider. From my point of view this is absolutely not needed. LR could just check if the ALT/ Option key is pressed when a slider changes it's value - these two conditions (ATL/ Option key pressed + slider value changes) are enough to toggle to the alternate display.

This would automatically solve all remaining problems that exist when not "clicking" the slider:
 - changing the slider via the LR API
 - changing the slider via keystrokes (like with VSCO keys)

Should be easy to solve with access to the source-code 🙂

...but: a dedicated (new) API entry for "changing the values with alternate display enabled" would be fine, too.

We would need something like "enable alternate display", then change the values and then "release alternate display" - otherwise the display would just flicker and would be toggled back to normal, if the value does not change anymore....

I think the best approach to the A.t/Option key issue is to do it in the API rather than work on better keystroke capture. This should be easier to do, and my users are typically not using the keyboard at the same time as the midi device. So, there could be a function for  alt/option that toggles the pressed state, or there could be additional parameter names that not only adjust the underlying value but also signal that it the Lightroom interface should act as if the alt/option key were pressed. For example, SharpenRadius could have a matching SharpenRadiusAltOpt that would adjust the SharpenRadius parameter but showing the display one would see when the Alt/Opt keys were pressed.

I just saw that you did know about this problem for more than a year.
It makes me very disappointed that a company like Adobe does not manage it to fix a bug in a year --- even worse: that you even did not start working on a solution.
