Bonjour, I have laptop with a wheel for the sound volume and I tried (without success) to make work under fc4 using xmodmap. First, I used xev which return: keycode=174 when I turn the wheel clockwise and keycode=176 for counter clockwise. So put keycode 176 = 0x1008FF13 keycode 174 = 0x1008FF11 in a .xmodmaprc and run xmodmap .xmodmaprc Now, xev returns: KeyPress event, serial 29, synthetic NO, window 0x2e00001, root 0x131, subw 0x0, time 2623843, (82,114), root:(88,526), state 0x0, keycode 176 (keysym 0x1008ff13, XF86AudioRaiseVolume), same_screen YES, XLookupString gives 0 bytes: XmbLookupString gives 0 bytes: XFilterEvent returns: False and KeyPress event, serial 29, synthetic NO, window 0x2e00001, root 0x131, subw 0x0, time 2623344, (82,114), root:(88,526), state 0x0, keycode 174 (keysym 0x1008ff11, XF86AudioLowerVolume), same_screen YES, XLookupString gives 0 bytes: XmbLookupString gives 0 bytes: XFilterEvent returns: False But nothing happens to the volume level.... What did I miss? Merci -- François Patte UFR de mathématiques et informatique Université René Descartes http://www.math-info.univ-paris5.fr/~patte
