[SOLVED] sda3 = 100% full, and I can't figure how to clean it out.

Question

It turns out my sda3 partition is 100% full.  My immediate reaction to this apart from being irritated was to clear my pacman cache, thinking this would solve the problem.  It didn't.  I've also tried pruning out some egregiously large log files but that doesn't do anything either.
Apart from clearing the cache and getting rid of log files though I'm not sure what else I can do to get this thing trimmed down to size.  Presumably someone out there has run into a similar situation and solved it?  Any advice on how to deal with it?  Thanks for your time, everyone.

Answer 1

Oddly enough, I just came home with intent to keep hacking away at this issue and I found that I was able to run xinit.  I hadn't been able to do that before due to this disk space issue but I certainly won't say no to a little deus ex machina action.
Here's some more info now that I'm back on the machine itself:

Per your suggestion, karol, I downloaded ncdu and ran it.  Here are the results.
