Mouse Doesn't Work with X

["Peter Kim" <peter@twinsun.co.jp>]

Greetings all,

I just installed my first copy of Linux.

Problem:
X starts fine.   I can use ALT key combinations to get a pop up menu and
select menu items.  However, I can't use my mouse.  That is, neither
clicking nor moving the mouse has any effect.

What I did:
I confirmed that my mouse is, in fact, PS/2.
I confirmed that my mouse is connected to the correct port.
I boot Linux.
I login-ed as root.
I ran 'xf86config' and selected 'PS/2' as my mouse.
I started X.
Mouse doesn't work. :-(

What I checked:
A coworker helping me checked the boot log with 'dmesg'.  We found a line
that says "Detected PS/2 Mouse Port".  Sound like good news...
We checked to see if the XF86Config file was written write.  Sure enough,
the mouse is PS/2.  This looks good too...

My plea:
I don't know what the heck is going on here.  What could be wrong?  Can
someone please help?

If I've commited any Netiquette rudeness or some such, I apologize in
advance.  I'm new to this! :-)  I think I've described the problem in
sufficient detail; however, if I've left some important information out,
then please tell me. I'll be more than happy to respond.

Thanks,
Peter
