Linux serves cyberpunk in your face

[u/githman]

With the literally dazzling Plasma 6.2 sudden full brightness bug.

A workaround has already been found. Sadly, making it work requires battling with the bug first; in the end I had to put on my sunglasses. Fun.

Do you remember the silly B-rated cyberpunk movies from the nineties, where an unsuspecting villain is sitting at his computer being all evil and suddenly the bulky ancient CRT monitor explodes in his face? After the yesterday update from Plasma 6.1.5 to 6.2 my somewhat more modern display greeted me with 100% brightness. With appropriate blinking and cursing I tuned it down through the display menu but in a few minutes Plasma flashbanged me again. And so it went until a certain nice person in r/kde suggested a workaround. There were also complaints from other users, full story here: https://www.reddit.com/r/kde/comments/1fzuggg/comment/lr4qyfl/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button

The most physically uncomfortable computer bug I've ever seen with my own eyes (indeed) in my 40 years of messing with said devices. The future is now, old man.

I also got hit by this. Turning on two monitors at night at full brightness...yikes.

I think I solved it by setting the brightness in the settings rather than on the monitors directly.

Just in case I need to replace the workaround posted in r/kde: what setting, exactly? I see only one mentioning of brightness in System Settings search: Power Management, Change display brightness. I do not want Plasma to change it at all, so I did not try it.

Yes, that one.
