tioantonio, Did you try this with the new kernel as Ben suggested above? Also, could you please provide the requested debug information (Which I repeat below):
Could you please provide the output from lspci by going to Applications->Accessories->Terminal could you also run sudo gedit /etc/X11/xorg.conf and try to change the Section "InputDevice" Identifier "Mouse1" Driver "mouse" ... Option "Protocol" "Auto" to Section "InputDevice" Identifier "Mouse1" Driver "mouse" ... Option "Protocol" "PS/2" and then doing ctrl alt and backspace but be carfull to have no unsaved documents open because this will restart your graphic system. You can attach logs and files when you add a new comment. Thanks in advance. -- optical mouse problem https://launchpad.net/bugs/36462 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
