Just curious if anyone knows of any way to configure the official touchscreen to show a black and white/grayscale display. I think ideally I want to customise the saturation/digital vibrance. I'm trying to create a retro device so black and white suits the aesthetic.
I've messed around with various methods with no luck including xrandr, xgamma, configuring x11 conf files with grayscale etc but I think the nature of the graphics drivers means these are all unsupported.
I did have some success with xephyr and it's grayscale emulation but that's causing videos to be very blocky and low quality, so I'm hoping for a better solution?
I'd really appreciate any advice or help!
