display brightness varies randomly

Hi,

I when opening new windows (sometimes), scrolling firefox or in the file manager suddendly the screen intensity goes down to about 50%. Continuing to scroll - brightness comes up again and maybe after scrolling more goes down etc. It seems to be dependent on the contents of the window, OR color of some areas etc.

Where can I make sure intensity is never manipulated by the driver? Where can I find more on how display brightness is manipulated?

I am using a 24in LCD display of 1600x1200 and nVidia GeForce 7300GT.

Many thanks.

Which driver are you using?

And where did you install it from?

can you reproduce this at exactly the same point of scrolling, say is it
exactly in the same place or is it random?

Does it only happen on certain sites or any web page with or without
pictures, flash, java things.

I cannot find anything in the driver that will dynamically adjust the
brightness, looking at the machine here with a 7300 in and there does not
seem to be that option anywhere.

Are you using KDE or Gnome, if you have both installed then does it happen
in both or just one?

Just trying to narrow down what is causing it.

Silly question but have you made sure your monitor cable is in nice and
tight ( both ends ), also what power supply and the rest of your hardware
just in case it is a power prob or a dodgy connection.

and, 1) don’t post the same question in multiple forums, 2) but, if
you do at least give the same, and most complete info in each…

your other posting didn’t mention your problem was in Firefox and
“file manager” by which i guess you mean Konqueror or what? (there
must be at least 50 different “file managers” available for openSUSE?)
