Dear Kurt,

since an automatic update of by the update-manager I also have problems with the keys and the lcd backlight.

I first had 0.24 installed, for which all was working fine. With 0.25 I got a completely dimmed screen. After reading some posts on the internet, I thought I should have installed the nvidia-bl-dkms instead of the mbp-.... version. This didn't help, and I now have both installed at the same time.

Backlight control is not possible anymore, since /sys/class/backlight/ was empty. I then saw that mbp-.... was not loaded so I did

sudo modprob mbp_nvidia_bl , which fills this directory again. I can now manually adjust by echo XXX >/sys/class/backlight/mbp_backlight/brightness.

I noticed that the max_brightness value is ***** 110400 **** INSTEAD OF 15 !!

So now, when I start pommed manually (pommed -d), it sets the brightness to practically zero (15/110400).

Pommed won't accept a initial level of more than 15 in the /etc/pommed.conf file, so as soon as pommed runs, your screen goes off.
I __CAN__ adjust it with pommed, but it takes forever, with these small steps of 1. Somehow, it _does_ allow you to change the stepsize to 500 or so.

Now it seems to work, with these keys (f1,f2), but I do not the notify window popping up for this (but I do for volume control, or eject).

SO: the problem is partially related to the levels, which were 1-15 and now are 1-110400
