I was thinking the other day how much cooler flap displays at stations and airports were compared to modern displays.
Such a nice interface between computer control and a purely mechanical display. Watching them update, flipping through all the variables to land on the right one, and then clearing was so cool.
I miss the noise they made too. Haven’t seen one for like 20 years now.
My 2012 MacBook Pro has exactly the opposite behaviour on a clean install across multiple distros. The brightness keys do nothing until after a suspend, then work fine until the next reboot. Never found a fix.
