Hi,
I seem to have more light sensitivity than flicker sensitivity. I also can't use dark mode, due to an astigmatism.
I am looking for a good Linux laptop. Among other things I'll need a good dimmable screen.
I can't go to computer stores to look there, because the bright flashing lights and loud noise make me sick, and mke it impossible to check screen brightness.
Notebookcheck has a partial listing, and can show minimum brightness with other data. https://www.notebookcheck.net/PWM-Ranking-Notebooks-Smartphones-and-Tablets-with-PWM.163979.0.html It doesn't look like there are any manufacturers which reliably provide usable screens. It also doesn't list anything I have used without trouble, so I can't find a good baseline.
