Encompass: No, it does not dims when I play videos with either Totem or
VLC. It dims only during boot, AFTER grub, before the login screen. And
on the login screen I cannot change brightness, only after an user have
logged in.

Is there any way to have a "slow boot" so to debug WHERE it dims?

I've tried videotaping it, but it's hard to see when it starts to dim,
which is not suddenly, it dims gradually, slowly. But it SEEMS to be
when it loads:

[at 59.2684] NVRM: loading NVIDIA UNIX x86 Kernel Module 169.12 Thu Feb
14 17:53:07 PST 2008

Or it might be:

[at 59.3426] uvcvideo: Found UVC 1.00 device HP Webcam
[at 59.3461] usbcore: registered new interface driver uvcvideo
[at 59.3462] USB Video Class driver (v0.1.0)

These are the last "video related stuff" that seems to show up right
before the dim starts.

BEFORE the NVidia Kernel Module there's:

[at 58.9249] nvidia: module license 'NVIDIA' taints kernel.
[at 59.2622] Linux video capture interface: v2.00

As you can see, it all happens in less than one second, without pausing
the boot process is impossible to pin point the exact moment it starts
dimming. But I don't know if it's possible to have a step-by-step boot
process. It's not really annoying to me, adding the brightness applet to
the panel helps to quickly change it, but if there's anyway I can help
with this bug let me know.
