  Now I'm trying to switch over to using the ps/2

 problem with it which someone here may have encountered before. The
 mouse seems to work fine in the terminal window but when I go into x the
 pointer jumps all over the screen, brings up the desktop menu...
 basically goes crazy.
 I have looked into this for the past few hours and cannot find anything
 specific to it online. I have tried every combination I can think of for
 the XF86Config file too.
 Has anyone encountered this and know the fix? 
Likely causes:
        gpm is configured and both x and gpm are using the same device
        gpm is configured, X is using /dev/gpmdata and the repeat type
                isn't raw, and X is getting the wrong mouse protocol
        gpm is configured, the repeat type for gpm is raw, X is using
                /dev/gpmdata, but protocol in XF86Config is incorrect.
Check /etc/gpm.conf repeat_type and device
Check /etc/XF86Config-4 Option "Device" and Option "Protocol"
If you are using gpm, it is recommended to set repeat_type=raw
and in XF89Config-4 use Option "Device" "/dev/gpmdata" and
Option "Protocol" whatever your mouse is.
