  1. In the globalkeys = awful.util.table.join( section of ~/.config/awesome/rc.lua: 

        -- Brightness

    awful.key({ }, "XF86MonBrightnessDown", function ()
        awful.util.spawn("xbacklight -dec 15") end),
    awful.key({ }, "XF86MonBrightnessUp", function ()
        awful.util.spawn("xbacklight -inc 15") end),

  2. 1) Install xbacklight:

    sudo apt-get install xbacklight

    2) Test it in console:

    xbacklight -inc 10
xbacklight -dec 10

    3) Add hotkeys to your awesome config ~/.config/awesome/rc.lua

    Insert inside [globalkeys = awful.util.table.join] section the following text:

    awful.key({ }, "XF86MonBrightnessDown", function ()
    awful.util.spawn("xbacklight -dec 15") end),
awful.key({ }, "XF86MonBrightnessUp", function ()
    awful.util.spawn("xbacklight -inc 15") end)

    I use a keyboard without XF86MonBrightness* that's why I added bindings to Mod+o, Mod+p:

    awful.key({ modkey,           }, "p", function ()                           
    awful.util.spawn("xbacklight -dec 15") end),                            
awful.key({ modkey,           }, "o", function ()                           
    awful.util.spawn("xbacklight -inc 15") end)

    Hope this helps )

  3. I autostart xfce4-power-manager, which will let you adjust the brightness using the brightness keys, in addition to general power management, such as suspend/resume, battery notifications, etc.

  4. One way is to load "gnome-power-manager" inside awesome, or at awesome startup: https://wiki.archlinux.org/index.php/Awesome#Transitioning_away_from_Gnome3 Hope this helps

    Another option is to run awesome inside gnome, then you can just rely on the gnome controls (working fine) and networking etc is working too http://awesome.naquadah.org/wiki/Quickly_Setting_up_Awesome_with_Gnome

  5. To make an app autostart when you login in Awesome WM: Right click on Desktop go to awesome > edit config. append the following line at the end:

    -- Autorun programs in Awesome WM
autorun = true
autorunApps =
{
   "xfce4-power-manager",

}
if autorun then
   for app = 1, #autorunApps do
       awful.util.spawn(autorunApps[app])
   end
end

    Replace "xfce4-power-manager" with your power manager.
