System policies prevent you from getting the brightness level (KDE)

Does anyone know how to (permanently) get rid of this?http://img715.imageshack.us/img715/5496/policykit1kde.png

As you might have guessed, typing the root password and pressing OK has no effect.
This is NOT a laptop!

i see in Personal Settings - Configure Desktop > System Administration >
Actions Policy > org.kde > powerdevil > KDE > Get Brightness (and also
Set Brightness)

if i click on “Get Brightness” it asks for a root password and then show
me my settings:

Any - No
Inactive console - No
Active console - Yes

and in the “Local authorizations” i see
“org.kde.powerdevil.backlighthelper.brightness *group has the following
policy: ‘yes’ on inactive console, ‘yes’ on any console,”

now, i have NO idea what you should do, but i know with my brightness
settings (which i’ve not messed with that i know of) i have never seen
your error…

if you wanna change to no, no, yes its ok by me, but i’d suggest you
click on the “Help” button in the lower left corner, AND read my caveat
first!

btw, mine is a netbook if that means anything…

btw2, maybe your monitor has a sensor to determine and auto-adjust your
backlighting according to room illumination…

There is an upstream bug report for this, you may want to comment on it
https://bugs.kde.org/show_bug.cgi?id=269310
I do not know a solution or a workaround so far.

Same thing here (even if I press Cancel at this warning)

I might have tried to disable powerdevil (or even succeeded) but I cannot remember where.

I can not find “Local authorizations”. (?)

Yes … I see errors that only few people get to see … I must be one out of 6 (as my wife always says). But I have this error on any machine on which I installed 11.4 - just saw it on another monitor around here.

I read your caveat already out of curiosity, as did probably everyone here at least once.

Yes, I found that while looking for an answer. I have to do some more testing. Maybe it is related to the way I usually start kde and X in general (from startx). I have to wait and see if it also happens when the session is started from kdm or gdm. I believe I’m missing something.

I have the same problem with my OpenSUSE 11.4 using KDE 4.6 on a laptop with an nVidia GPU. It turns out this is a wider known bug, with a known solution: “https://bugzilla.novell.com/show_bug.cgi?id=688267”

I have this window each time i switch from a graphic user session to another (ctl+alt+f7 <-> ctl+alt+f8) .

Actually I don’t have laptops and I’m quite sure - after using KDE for a while on several computers - that it happens only (for me) when I start KDE directly from console (startx) without a session manager (xdm,gdm,kdm) and even, I guess, whenever I start KDE from console without having started it before from a session manager. In any case, it is definitely a polkit issue. I’ll try this hack asap.
