Try use the xev command just to see if it reacts when you push a button
If yes note the keycode numbers it displays (keycode 223 for example)
in a file. After that, create a .Xmodmap file in your home dir.
mine looks like this :
Code:
keycode 234 = XF86AudioPrev
keycode 233 = XF86AudioNext
keycode 232 = XF86LogOff
keycode 236 = XF86Mail
keycode 229 = XF86Search
keycode 230 = XF86Documents
keycode 178 = XF86Start
keycode 235 = XF86HomePage
keycode 161 = XF86Calculator
keycode 223 = XF86Standby
Then restart X and use the wm to assign buttons to commands
