Hi, I have Xfree86 server 4.2.0 installed on my Mandrake 8.2 and I also got a new Microsoft Trackball Explorer 5 buttons mouse.I'd like to make all these buttons function,so I changed the /etc/X11/XF86Config configuration, Section "Pointer" Protocol "ExplorerPS/2" Device "/dev/psaux" ZAxisMapping 6 7 Buttons 7 But when I restart X-windows using command startx,I got the following error: Config Error:/etc/X11/XF86Config:124 Protocol "ExplorerPS/2" Mouse type not supported by this OS Mouse type not supported by this OS. Could somebody help me? P.S,I did these change on another same PC,no problem.I can't find out why. Thanks a lot. _______________________________________________ Newbie@XFree86.Org *** To unsubscribe , or change message options, see: http://XFree86.Org/mailman/listinfo/newbie
