Discovered xev on another list, but it is installed on FC7. xev will open a little window for you to play with all of your mouse buttons and scroll wheel in. Just use a terminal window to launch it on the command line with "xev". It's really simplistic and sweet, pushing your mouse buttons will tell you what xorg button number is seen with the button press. I just hooked in an USB GE two scroll wheel optical mouse. One scroll wheel is slightly behind the the normal clickable one that is seen. Plus there are two other buttons on the left side. xev sees: Left main button : 1 Scroll wheel button : 2 Right main button : 3 Scroll wheel forward : 4 Scroll wheel back : 5 2nd Scroll wheel forward: 6 2nd Scroll wheel back : 7 First Side button : 8 Second Side button : 9 Using the original xorg.conf, when I unplugged the PS2 mouse and plugged in the USB mouse, the second scroll wheel was seen as buttones #6 and #7. Well, I DINKED with xorg.conf and now it's not seen at all. I restored the original xorg.conf file and it still is not seen now. <sigh> I used the mouse-driver man page found at http://www.die.net which explained the defs used for mice in xorg.conf. Question 1: option "buttons" should be listed as "buttons" "9" or "buttons" "1 2 3 4 5 6 7 8 9" or "buttons" "1 2 3 8 9" when you have 9 expected buttons or 5 actual buttons with 4 5 6 7 assigned to scroll wheel buttons? It's not plain and several other web pages found by google show options "buttons" "1 2 3 4 5 " instead of a single number for a single scroll wheel mouse with three switches and two scroll wheel switches. God, I hope I'm not confusing everyone. :) Question 2: what is the difference in the use of ZAxisMapping, XAxisMapping, YAxisMapping?? I've tried: Option "ZAxisMapping" "4 5 6 7" and option "XAxisMapping" "4 5" option "YAxisMapping" "6 7" --- none seem to work. But I know that at first, before I screwed with everything that buttons 6 and 7 were reported in use by xev. Now they do not respond. Someone shoot me now or help me from the darkness. I need the relief either way. :) Ric -- ================================================ My father, Victor Moore (Vic) used to say: "There are two Great Sins in the world... ..the Sin of Ignorance, and the Sin of Stupidity.
