configuring the mouse in Ubuntu

[Russel Caldwell]

OK, I've banged my head on this for quite a while and haven't been able to
figure it out. The mouse on my desktop is not responding and I'm not sure
how to fix it. One Ubuntu post said there were a couple of utilities called
xf86config and xf86cfg but I haven't been able to find them. I've tried to
change the file /etc/X11/xorg.config but I think I made things worse because
mdetect can't detect the mouse anymore. What do I need to do to make my
mouse work again in Ubuntu?

Thanks.
