'gmp.conf':

#  /etc/gpm.conf - configuration file for gpm(1)

#  responsiveness=15. append can contain any random arguments to be
#  appended to the commandline.

#  If you edit this file by hand, please be aware it is sourced by

responsiveness=5.

O mouse fica dando "saltos" na tela, ou seja, eu arrasto o danado, e de repente, ele se move para uma posição completamente distante, dando um monte de cliques, de modo que pop-up menus são acionados do nada!



Alguém tem alguma idéia?

Grato,
