backlight

I'm new to the community, although I have been using Ubuntu since 2010. I have a Samsung Q210 notebook; Specs:

Intel® Core™2 Duo CPU P8400 @ 2.26GHz × 2
4 Gigs RAM
Nvidia 9200m GS (although system information in Ubuntu doesn't know)
194 GB HD

OS: Ubuntu 11.10 Kernel is 3.0.0-12-generic-pae

Although Samsung seems to be infamous for problems with Ubuntu, after upgrading to Oneiric, finally the FN Brightness Buttons are recognized. The only problem is, after dimming the backlight for a fixed amount of steps (3 or 4, I dare not count now because that would mean rebooting because I can't see anything), the display goes completely dark and using the FN buttons to brighten the backlight does not work anymore (before reaching that threshold, going brighter after dimming works).

Now what do I do? File a bug report? If not, what then? If yes, how? Not sure... guess I should ask here first.. thanks for answering in advance.
