Specifically, I'm trying to get RStudio to work on Ubuntu 12.04. Yesterday it was working fine, but now when I either click or try to start it from terminal, exactly nothing happens. The prompt returns nothing, the click produces nothing. What could have caused this and how do I fix it?

Found the issue.

For some reason, locale issues were causing it. When trying to run r from terminal, there was some locale related error message, so I just generated and reconfigured a new one as described here:

Suddenly RStudio was working fine.

Try putting apparmor in complain mode. this may allow Rstudio to work as well as give clues as to why it's throwing that DENIED at you.
