Debian Multimedia :: Graphics Stop Working After Upgrade To Jessie

I upgraded from wheezy to jessie, but now I just boot to a console. I've gone through and made sure all packages are up to their latest versions, and I've made sure gnome, xorg, and xserver-xorg are reinstalled (during the upgrade they got uninstalled..).

Here's what happens when I run startx manually:

Code: Select allcharlie@asimov:~$ startx
X.Org X Server 1.16.4
Release Date: 2014-12-20
X Protocol Version 11, Revision 0
Build Operating System: Linux 3.16.0-4-amd64 x86_64 Debian

[Code] ...

Note also that this whole time, gdm3 has been running:

Code: Select allcharlie@asimov:~$ ps ax | grep gdm3
 1058 ?        Sl     0:00 /usr/sbin/gdm3
 3993 tty2     S+     0:00 grep gdm3
charlie@asimov:~$ sudo service gdm3 status

[Code] .....

I'm not sure why it prints that it's starting gdm3, but it does that every time I run `sudo service gdm3 status'.

Here's a copy of my /var/log/Xorg.0.log.
