Unofficial Luma build discussion

Apologies for the slight delay, I was wrestling with the "new feature". The latest build now has Luma 10.2.1 and should therefore be compatible with system version 11.14.

The new feature is being able to set screen brightness below the preset minimum down to 1. Thankfully, the official Luma team provided the calculation to convert 'luminance' to brightness, but it took me a lot of trial and error to get the LCD registers to update correctly within a useful control flow (for reasons that I don't really understand XD)... Anyways, there are a few slight 'glitches' with using the low brightness, but there should be no impact on the regular and extended upper brightness limits.

 

No worries, the "Change screen brightness" interface works similarly to the official Luma version. When you select it from the Rosalina menu there is an explanation of the controls. However, tt might be that you need to press start first so that you can see both the top and bottom screens. Then try adjusting left and right a few times to see if there is a noticeable change in brightness.

 

Apologies, it's not something that I test for personally so it's probably been broken for a while. I brought in some changes from Nanquitas & PabloMK7 that I had missed before. Hopefully that will have fixed it.

New update expands on the TwlBg switcher PoC to now include AgbBg.cxi switching and open_agb_firm config.ini switching. Optionally, I'd suggest setting up Stellar's Open AGB Launcher as it allows you to suppress the power LED via Rosalina before launching into open_agb_firm from a home menu icon.

 

TwlBg.cxi is a file generated using Sono's TWPatcher. It allows you to choose different scaling and filters to apply in DS/i mode. Unfortunately, it's not able to turn down the actual backlight level like Rosalina can, but you are able to apply a bluelight filter and faux brightness-reduction filter.

Minor update: The Official Luma team added a new feature to show extra battery details that I thought was cool so I wanted to grab it early. Also, the custom screen filter interface will now display the previously saved values for the top screen on loading.

 

Thanks, though I guess it's not really "full-auto" since it still needs to be applied via Rosalina first, but it does have the newer feature of being reapplied after sleep. I am interested in the idea of lowering the backlight and applying redshift as early as possible via holding a button when Luma is booting up. I'll need to experiment to see if I can get the timings right.

Absolutely, gotta catch 'em all! Your pioneering hardware work was what got me motivated to aggregate and tweak interesting Rosalina features haha. All that stuff sounds great, I just might actually have to work out how best to make features optional with config now XD.

I forgot to check that . Patching SetBrightnessRaw sounds like a good plan, but I wouldn't know where to start on doing it XD. I was able to get low brightness working for now though with a hacky implementation.
