Sorry, I expressed myself wrong
, I was tanking about the protocol really ...
The mouse I had the problem used the same protocol, imps2, was configured in X just like yours, but in gpm was configured using just ps2, when I changed to imps2 it solved the problem. In my distro, the configuration file is /etc/sysconfig/mouse, is like:
FULLNAME="Microsoft IntelliMouse (PS/2)"
