I have a Microsoft PS/2 mouse and a Generic Serial mouse. I tried them both on Linux in mouseconfig but every time it clicks in "Emulate 3 Buttons" even though I never clicked it. When I used the Microsoft PS/2 mouse, I tried to go into X-Windows the mouse always fails and the system crashes, but when I use the Generic Serial mouse I can move the pointer but the movement isn't smooth and the pointer jumps all over the screen and I cant control it.
*** Bug 1698 has been marked as a duplicate of this bug. *** With MS mouse attached to the ps2 port of an alpha, ran mouseconfig selected generic ps2 mouse, checked emulate 3 buttons. The paste operation fails in a VC. Works in X.
It turns on emulate 3 buttons because 2 button mice NEED to have the third button emulated. What are the contents of your /etc/sysconfig/mouse when you have the microsoft PS/2 mouse attached? What sort of microsoft PS/2 mouse is it? (model numbers on bottom of mouse).
Please also note that after you change your mouse type with mouseconfig, in Red Hat 5.2 and earlier, you NEED TO RE-RUN Xconfigurator for X to pick up your mouse changes. This will not be the case in the next release of Red Hat Linux, but as it is now, it is clearly stated in both mouseconfig and the mouseconfig man page.
