There should be backlight adjustment keys on your keyboard. If those
don't work, then file a kernel bug. In Gnome, if you open the menu in
the top-right corner, there should be a brightness slider under the
volume slider. Again, if that doesn't work, it's most likely a kernel bug.

not familiar with 'gnome thinking', but i guess volume slider is a good
a place as any to include a brightness slider.
as for filing a bug, a 'need to know' is if current version of
'xbacklight'
works with his video chipset. if laptop is old, fedora may have dropped
his chipset. if 'new out of box', current drivers may not work.
Patrick needs to run 'lspci|grep vga' to find his chipset and post it to
see if others with 'xbacklight' working have same chipset.
failing that, joining developers list would get faster reaction than
filing a bug report.
If you open a terminal and look in /sys/class/backlight, each
directory
there represents a kernel backlight control interface. Inside, you can
write a number to "brightness" in the range 0 to "max_brightness" and
it
should change. Be careful writing something very low because you might
not be able to see to turn it back up.

above is covered in search link i posted. did not mention because if
Patrick reads thru search, he will find several links on same and in
more detail.
