Bug#803112: gdm3: Black/grey screen with unresponsive mouse cursor on GDM start

Package: gdm3
Version: 3.18.0-2
Severity: important

Dear Maintainer,

When I boot up, upon gdm3 loading I am presented by an unresponsive mouse
cursor and either a black screen (if I have two monitors plugged in) or a grey
background (if I have one monitor plugged in). Either way I am unable to login.
I am also unable to switch console with Ctl+Alt+F*. The only thing I can do is
Alt+SysRq+(R,S) which kills gdm3 and gets me back to the console.
   * What led up to the situation?
        I ran an upgrade on 24 October.
   * What exactly did you do (or not do) that was effective (or
     ineffective)?
        I tried adding user Debian-gdm to the video group (see bug #799948),
which did nothing.
        I tried to access Xorg via the startx command which works.
        I tried enabling automatic login, this also works and so acts as a
workaround / temporary solution.

Am using the intel Xorg driver (for an Intel 4000 chipset) and have a feeling
this problem may have something to do with it going by the errors below.

***I found the following errors in my journal which started appearing almost
immediately after I upgraded on 24th:***
