Debian Multimedia :: X Broken After Update - Screen Remains Black

So I'm pretty awful at keeping Debian up to date, I guess. I'm using cron-apt to fetch updates every night, then apply them whenever I get around to it. Well, I neglected that last part for a month or two, and after some routine downtime to clear the case of dust, I decided it was time to upgrade. So I ran the command, everything checked out fine, and I was on my merry way. Until a half-hour ago when I accidentally shutdown the computer (I use the same zsh prompt on each computer, so I got them confused.) I turned it back on, only to be greeted with a black screen after all the services started up.

Everything works: ircd, MPD, etc. EXCEPT, of course, X. At first I thought the update broke SLIM, but after checking htop and doing a killall slim, it doesn't appear to be running (the screen remains black.) I hit Control-Alt-f2 to get to get back to a terminal, then tried doing startx, which freezes the computer entirely. All the network services stop, I can't SSH in, etc. It's dead. If I'm not mistaken, Xorg.0.log should say something, but I'm not a huge expert on it. The last line isn't an error, I can tell you that. So what's the deal here? apt-get remove xorg and start over?
