I have been trying to install different packages via Terminal, like
xserver-xorg-input-mtrack, but it never works because I get the error:
Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package xserver-xorg-input-mtrack
Normally I have been able to install this stuff through the Synaptic Package Manager, but I can't find there the "mtrack" driver.
Any idea why
apt-get is not working? I have already run
sudo apt-get update several times.
EDIT: I'm running Ubuntu 11.10 in a MacBook Pro with dual boot (Leopard)
