Hi
I have an HP notebook with nvidia drivers and kde 4.6.1. I control the brightness through nvidia-settings and since i'm a nvidia user, the brightness control with powerdevil or some kde program doesn't work. My problem is that the plasma brightness OSD suddenly appears, apparently by a random trigger. I checked the shortcuts, and tried changing them, but that doesn't work at all. Could I disable the brightness OSD? i don't use it, I don't need it, would be a very good solution for me. I checked google, but i didn't find something.



PS: The OSD responds correctly to shortcuts, but it still appears randomly
PS2: With kde 4.4 this didn't happens.

Does this happen when you're idle, or while operating normally? To disable it, you may want to change your power profiles in System Settings and set all of them at the same brightness value.

It happens idle or operating normally.
Yesterday i thought the same, and I disabled the brightness display control in system settings for all profiles, but that doesn't work (without restart). Today, after a system restart, the osd is totally disabled. Recently, i'm having problems with my battery, apparently no longer works, my system BIOS show me a message appointing to this and maybe power control works erratically because of that. It's just that my battery problem arose together with my kde upgrade

Right, this may be as well be the cause. Likely not a bug then, just an odd combination of factors playing all at once.

Hmm, i just was viewing a pdf (okular) in presentation mode, and osd suddenly appears . After that, it appears a few times too. How i said before, I have disabled brightness control in control settings for all profiles, and by the way all profiles have the same brightness setting (but that shouldn't be important because i have disable them). Right now OSD appears less, but still appears.

Is there a (hard) way to disable it? i mean, change some config file or something like that?

Untick "Dim Display" in your power profiles. That's a kernel bug.

Will it not cause him to lose the functionality? He only wants to lose the OSD indicator and not the feature itself.

It's not the brightness he will lose. It's the backlight that's not working from what i read. The osd icon is the same as for brightness.

I control the brightness through nvidia-settings program, kde power management cannot control the brightness in system with nvidia drivers.
I have already disabled brightness from kde settings ("untick solution") and it has worked "almost" perfect.
how i said, i've had some battery problems, maybe that's the cause of this strange behaviour.
Right now, it seems that osd suprise has already dissapeared (or almost)

Sorry for necrobumping, but I thought it was better to resuscitate an old topic instead of creating a new one on the same subject.
I have the same issue, but it occurs only with SC 4.9.4. Never had it before. Besides, the kernel version was the same with both 4.9.3 and 4.9.4, so it might also be a kernel bug, but it's definitely triggered by some KDE SC 4.9.4 component.
Unticking "Dim Display" is not a viable workaround, since I lose the DPMS features.
My laptop ships an Intel graphics card (Core i5 Arrandale).
Does anyone else has the same issue?

Does the brightness OSD disappear after a short period of time as it is supposed to?
Also, is there any particular event (like the changing of a Power Management profile) which triggers the brightness change?
