PS/2 Mouse with Compaq Presario problem

["Ronald Castillo" <ronaldace@coolmail.net>]

When I try to run GPM using my PS/2 mouse, it seems like the program
disconnects my keyboard, because neither of them (keyboard and mouse) work.
I have a Compaq Presario 5030.  I used the following configurations:
gpm -t ps2 (didn't do anything)
gpm -m psaux (froze the computer)
Using gpmconfig and telling it to use the PS/2 Port also froze the computer.
I would really apreciate if you could help me configure my mouse (it's a
Logitech PS/2 Trackball).
Thanks in advance for your help.
