I recently installed Ubuntu 14.04.4 on my Macbook Air (late 2015). I want to fix the horrendous touchpad configuration that comes by default. So I searched and found that mtrack does that. So I tried to install mtrack with sudo apt-get install -f xserver-xorg-input-mtrack. But then I get an error
xserver-xorg-input-mtrack : Depends: xorg-input-abi-20
Depends: xserver-xorg-core (>= 2:1.14.99.902)
So I then tried to install either xserver-xorg-core or xorg-input-abi-20, but then I get
The following packages have unmet dependencies:
unity-control-center : Depends: libcheese-gtk23 (>= 3.4.0) but it is not going to be installed
Depends: libcheese7 (>= 3.0.1) but it is not going to be installed
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.
I have also tried using aptitude to install the aforementioned packages, but that actually crashed my Ubuntu GUI system and so I had to reinstall Ubuntu after that and I don't think that approach works.
