Got it, thank you for your help with this.  I used xbacklight along
with the xfce4 keyboard shortcut GUI settings.  My backlight
adjustment keystrokes are displayed as XF86MonBrightnessUp and *Down
in those settings, so there must have been a mechanism adjusting the
backlight based on that before I updated Xorg.  Here are my xbacklight
commands:

xbacklight -inc 15 -steps 1 -time 0
xbacklight -dec 10 -steps 1 -time 0

Thanks again,
Grant
