Controversial opinion: if your monitor is set to the proper brightness for the room's ambient light, light or dark theme becomes a matter of preference. If you're in a completely dark room with your brightness set to 100%, then of course a light theme won't work.
There are actually some models already with a built in ambient light sensor. I don't know how much of a convenience it would be, whether it would be distracting if small changes in ambient light make the brightness go up and down all the time. I personally prefer changing it manually - I have a macro pad with knobs which are mapped to do that.
I too, just disable the ambient sensor, but if I had to have one,
I'd rather have one that sends the sensor data to the PC, via an Open Protocol over DDC and let the KDE brightness setting handle the Brightness value decision (which would be easily configurable, of course).
Ok so most monitors sold today support DDC/CI controls for at least brightness, and some support controlling color profiles over the DDC/CI interface.
If you get some kind of external ambient light sensor and plug it into a USB port, you might be able to configure a script that controls the brightness of the monitor based on ambient light, without buying a new monitor.
Thank you! I hate how many people act like dark mode is The One True Way these days. No, I don't want to use feckin' dark mode, I'm sorry I don't have your 1337 h4x0r eyes. I have shoddy astigmatism eyes and find it very uncomfortable to use dark mode.
My problem is kind of the opposite - most light themes I've seen are too contrasty and I can't discern the different colours all that well, moreover too much contrast is tiring to my eyes. Black text on white background is about the same as white text on black background. Most of the time I prefer dark themes, but those with low or medium contrast.
Fair enough, whatever works for you - but I feel like this is more of an exclusion and the majority of people are just too lazy to set their monitor brightness properly.
Not an opinion, I have an actual situation with my eyes where they twitch uncontrollably when presented with bright lights for a long period of time. I have tried minimum screen brightness, lowered contrast/colors, auto brightness based on the environment, various software solutions to removing blue light 24/7 from the screen - none of it worked. Went permanently dark theme on everything, magically eyes haven't twitched in years.
Light theme vs dark theme is not just a preference, it's an actual accessibility need for some of us.
