hardy changes screen brightness to max

It also does this consistently at reboot.

The application at fault might be hald-addon-dell - this jumps to the second highest process on the list of processes (under dbus-daemon) when I run the 'top' command and then continually the change screen brightness manually.

kondemand, hald, and console-kit-daemon also figure high in the list when I do this.

I can confirm this.

I also want to add that the Manual Brightness Changing is behaving strangely. First, I incremented the brightness to Max. This is OK. Then I start to decrement the brightness step by step. However, the brightness jumps from the assumed level to Max and then back to normal level and then to Max. I mean, for odd numbered clicks it jumps to Max; while for even numbered clicks it is behaving normally!

Confirmed, though for me, it changes brightness to medium regularly. Manual brightness control is very jumpy.

I have a Dell XPS M1710 laptop.

Confirmed on an Acer Aspire 3613WLMi. Although the brightness doesn't go to max, it just increments upwards at what appear to be random intervals.

For a while between alpha 5 and 6 this problem changed for me so that it was only occurring when starting X (ie logon or resume), but now the random jumps to maximum brightness are back. (It is also resetting to max at login or resume.)

After today's updates, the screen no longer resets to max upon starting X.

HOWEVER, now when I press the FN-down arrow key to reduce screen brightness, my keyboard stops functioning for anything other than reducing or increasing screen brightness.

I reinstalled from Hardy beta and I no longer have this auto-brightness-adjustment problem.

Same situation here, with the screen periodically jumping up in brightness.
More, when scaling it down, it gets max and then becomes darker until I reach the top down.

I use thinkpad X300 and still have the same problem.

Every time I boot my Ubuntu Hardy, the brightness set to the max.

Brightness jumps occur more when running on battery power.

This doesn't appear to happen in natty. Closing.
