Comment 64 for bug 12637

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.
