Hi Adriano, Could you send us the whole output of /usr/share/bug/xserver-xorg/script 3>&1 so that we see your full X log and config and tell us whether you modified anything in your xorg.conf since then? Also could you send the output of lsmod so that we make sure all mouse-related kernel modules were loaded? (psmouse or so might be required for PS/2 mouse) Thanks, Brice
