Hi! I'm a relative newbie to Linux. I've recently installed RedHat Linux 7.3 on my IBM Thinkpad T20 and think it is generally very good, however I still have problems getting the mouse-wheel to work. I've browsed the net and tried all sorts of settings. I have a standard Microsoft Intellimouse 1.1A PS/2 scroll-mouse. Here is what happens: In /etc/X11/XF86Config the following was written by the installer: Option "Device" "/dev/mouse" Option "Protocol" "PS/2" This makes the mouse work, but without the scroll-wheel. I then tried to change it to the following as many sources suggest: Option "Device" "/dev/mouse" Option "Protocol" "IMPS/2" Option "ZAxisMapping" "4 5" Option "Emulate3Buttons" "no" makes the mouse-pointer go around like crazy. In other words, it doesn't work at all. I've also tried "intellimouse" for the protocol, but that didn't work either. Please help me before I erase Linux for good.
