Jeff: Ditto on that. I have a Dell with a TrackPoint AND a TouchPad as well as the PS/2 port in the back where I used to plug-in my wheel mouse. I setup my X to use the wheel mouse because that's what I used 90% of the time. It's when I went to the computer room to do some troubleshooting with my laptop that I ran into your problem. I had no place for a mouse so I was forced to use the TouchPad or TrackPoint and it was pretty weird. The problem lies with the fact that the wheel mouse uses virtual mouse buttons 4 and 5 to perform wheel operations that are simply not there for the TouchPad / TrackPoint. Also, the PS/2 device typically emulates a 3rd mouse button using the same virtual mouse buttons that the wheel mouse uses (ZAxisMapping "4 5"). So, there are two possibilities: 1) don't use a wheel mouse so you won't use the ZAxisMapping option (not what you're looking for) or 2) don't use 3-button emulation on your TouchPad / TrackPoint (better). You may still experience problems with plugging-in or unplugging the external mouse while in X. Unfortunately, X isn't Plug-n-Play so it won't recognize that you've switched mice. You must restart X (Ctl-Alt-Backspace) AFTER you plug-in or unplug your mouse. But I may have a better answer: use two different mice: an external USB wheel mouse along with the built-in TrackPoint / TouchPad (I have a Dell - it has both). To implement it, modify your XF86Config-4 file and make sure you have two pointers defined: one USB mouse and the other for the Trackpoint/TouchPad/PS-2 port, like this: Section "InputDevice" Identifier "TouchPad" Driver "mouse" Option "Device" "/dev/psaux" Option "Protocol" "PS/2" Option "ZAxisMapping" "4 5" EndSection Section "InputDevice" Identifier "USB Mouse" Driver "mouse" Option "Device" "/dev/input/mice" Option "Protocol" "IMPS/2" Option "ZAxisMapping" "4 5" EndSection Then, use a ServerLayout section and specify that both mice are to be used, like this: Section "ServerLayout" Identifier "Home" InputDevice "Keyboard0" "CoreKeyboard" InputDevice "TouchPad" "CorePointer" InputDevice "USB Mouse" "SendCoreEvents" Screen 0 "Screen LCD" EndSection It works! I use both the USB Mouse AND at the same time, I can also use the TouchPad and the TrackPoint devices. If I unplug the USB mouse, I can still continue using the TouchPad and TrackPoint devices without a problem. Also, note that in the "TouchPad" configuration, I did NOT define the Emulate3Buttons option so I won't have a great deal of difficulty using an external wheel mouse. Hope this helps.

When I configure it as a wheel mouse, or when I disable the trackpoint and use a PS/2 wheel mouse, the pointer gets all whacked out. It jumps to the bottom left corner and when you move it it also registers tons of right and left clicks by itself. If I try to move it too much it deletes my launchers and moves my menus because of all the random clicking. Anyway it appears that it's caused by switching the mouse protocol from PS/2 to IMPS/2. Any information what anyone can tell or point me to on PS/2 vs. IMPS/2 would be great. -- Jeff Bearer, RCHE Webmaster, PittsburghLIVE.com Winner 2002 Eppy Award, Best U.S. Newspaper Website -- Jeff Bearer, RCHE Webmaster, PittsburghLIVE.com Winner 2002 Eppy Award, Best U.S. Newspaper Website _______________________________________________ Newbie@XFree86.Org *** To unsubscribe , or change message options, see: http://XFree86.Org/mailman/listinfo/newbie _______________________________________________ Newbie@XFree86.Org *** To unsubscribe , or change message options, see: http://XFree86.Org/mailman/listinfo/newbie
