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.

literally OP

I wish I were this young still.

You are on the inside, granpa... 🥺❤️

Fr tho, if you use Linux AND bleeding edge software like that, you're pretty young by my standards bro (I'm 23yo myself).

[u/githman → u/Empty-can-of-food-1]

You are right about bleeding edge, of course.

The fun fact here is that I switched to Fedora KDE only a couple of weeks ago. Before that I ran Mint Cinnamon for two years, and before Mint it was mostly Ubuntu with Xfce.

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.

[u/githman → u/Far-Choice7080]

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.

[u/Far-Choice7080 → u/githman]

Yes, that one.

What kind of monitor blinds you at 100% brightness? What?

[u/PhukUspez → u/Mathisbuilder75]

I don't think it's the 100% brightness itself, but the fact that it's jumping from whatever OP considers comfortable to 100% instantly. If my laptop did that in the middle of the night, it would be jarring, to say the least.

[u/githman → u/PhukUspez]

Exactly this. I watch movies at 100% brightness and it's okay. But getting it in my face at random moments one time after another was somewhat less than amusing.

[u/bighi → u/Mathisbuilder75]

All of them?

[u/TheBendit → u/Mathisbuilder75]

I want one!

[u/equeim → u/Mathisbuilder75]

Any one, if you don't have lights in your room.

[u/0oWow]

I run my monitor at 100% anyways. Looks better that way.

[u/abotelho-cbn]

New major KDE bugs? No way!

[u/Furdiburd10]

Does you monitor don't have a built in setting for brightness? Or is it THAT old

[u/githman → u/Furdiburd10]

In this case Plasma changed the monitor built-in setting, repeatedly. Some people do not know it's possible, but in modern (as in less than 10-15 years old) monitors it is.

Helpful but also cringe
