Which software?

I fixed the isight camera using the firmware on my mac partition with:

su -c "ift-extract --apple-driver '/media/Macintosh HD/System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns/AppleUSBVideoSupport.kext/Contents/MacOS/AppleUSBVideoSupport' "

Installed wireless

broadcom-wl.noarch                   5.100.82.38-1.fc14      @rpmfusion-nonfree-updates

And video

su -c 'yum install kmod-nvidia'

I added some software packages as well. Here is the list:

That was the entire output of

yum list

Sorry about it. Had no idea of how to filter the added packages.

I just found some further about the bug.

When I press the backlight keys, The On-Screen-Display works. I can see the icon with the bar either being filled or emptied. However, the intensity of the backlight does not change.

Nevertheless, if I close the lid of my computer or if I suspend the computer, and then turn it on again, the intensity of the display is updated. If the value was low, then the screen will start up dark. If it was high, the screen will be brighter.

This is the non-free binary driver. We can't fix bugs in the binary driver, sorry. If you switch back to nouveau it should all work as it should.

Thanks. Now I see.
