I have a fresh, basic installation of Ubuntu 14.04 with Unity running through crouton on a new Chromebook, a Toshiba Chromebook 2 (CB35). You end up simply opening a chronos Chrome shell and calling
sudo sh ~/Downloads/crouton -r Trusty -t Unity
Upon installation, I immediately noticed that Gnome Terminal was not installed, or Ubuntu's Software Center or Software & Updates and others. I'm a first time Linux user so I used NetSurf to try to do a search and see what I could do but after a Google search but it kept refreshing, or re-sending the search before results appeared. I switched to ChromeOs and ended up using XTerm to install gnome terminal and the software center and grab a stable Chrome.
Now I'm trying to use Unity Tweak Tool to, well, tweak and I'm getting a lot of missing schema's from com.canonical.*. I've addressed two missing schema specifically but now I'm missing com.canonical.desktop.interface and solutions I've found don't resolve the issue.
It feels like I've missed something as my install is missing a lot of components. How do I check that everything essential or basic I need is installed or how might I be going about this wrong?
