After install Ubuntu on my laptop, i figure out that My logitech mouse doesn't work well on Ubuntu. I can't install setpoint on it therefor all the functionalities of logitech mouse gone. Digging the internet, i found out that many people has the same problem with me. And in Ubuntu forum i found out the way that you can setup your logitech mouse to have the "back" and "forward" button. (base on this
However be very careful when you follow the step because you my mess up your X session and it can't load any more. Make sure you follow the last step from the tutorial:
"Your touchpad may not be a Synaptics, but the main point is to show
that there is no "SendCoreEvents" option defined, and instead we give
the touchpad the CorePointer option which I highlighted. Basically it
becomes the "main mouse," and since the touchpad is always attached to
the laptop, you shouldn't get an X crash because of no mouse. If for
some reason you are using this mouse on a desktop with no other mice,
you'll want to place the CorePointer in with the logitech mouse
section, making sure you delete the SendCoreEvents line as well.
Finally, you need to head to the "ServerLayout" section of your
xorg.conf file and look for the "Configured Mouse" line, and change it
to "Logitech v450". Now, say your hail marys, and hit
CTRL+ALT+Backspace to restart X - make sure you understand how to
restore the backed up xorg.conf before you do.
"
Also backup your xorg.cof file before you modify it. So that you can restore if you have problem.
