I installed centOS but the backlight on the monitor doesn't work
I just did a fresh install of the latest centOS today. When I startx the GNOME desktop, my screen goes black. After I looked very very closely, I noticed I was actually in the desktop but with no brightness or light. I have to use a flashlight to view my screen or else I can't see anything.
Yeah, it seems so. Now, under Section "Screen", try adding the following line after Device "Videocard0":
Monitor "Monitor0"
I tried but then startx fails and GNOME gives an error saying screen is trying to reference Monitor0.
Apparently GNOME has a brightness applet but I can't find it so I'm not sure if everything there is correct. I also read about a file called xBrightness but I have no such file under /etc/x11
The config I posted is on a laptop so it should work for you. Try adding it to your xorg.conf and rebooting.
Dont' forget to add 'Monitor "Monitor0"' in the 'screen' section.
