Here's the situation: I'm using the tool "crouton" on an acer c7 chromebook to run xubuntu 12.04 alongside chromeOS. I mounted the 320GB partition onto "/media/test/", but the main partition which includes "/home/ryan/" (used by chromOS for most stuff) is only around 4GB and is completely out of space. I used ppa-repositories and apt-get to install a few programs in xubuntu and it looks like by default they were installed on the smaller drive.
My question is two fold:
1) Can I view hidden files and find any places in "/" that I can delete some files and free up space?
2) How can I do a apt-get uninstall & purge and reinstall the programs to /media/test/ where there is plenty of free space?
