[Bug 1302309] [NEW] X won't start after today's update on ubuntu 14.04

[jatin sachdeva]

Public bug reported:

I'm using a Lenovo x230 laptop and have been on ubuntu 14.04 alpha/beta
for last few months. Everything was fine with daily updates, till I
updated today and now X won't start up. The screen just hangs on the
ubuntu logo screen and sometimes gives a message "waiting for network
configuration" or "waiting for 60 more secs for network configuration".
However it goes nowhere and does not give me a login screen. If I change
display manager to lightdm, I get a login screen but nothing happens
post login - just the wallpaper n mouse pointer. I've checked and I do
have network connectivity from the terminal (ctrl-alt-f1). I've also
tried uninstalling and reinstalling xserver-xorg and then doing a dpkg-
reconfigure xserver-xorg but didn't help. Booting in fail safe graphics
also doesn't bring up X. Seems like an upgrade issue or bug. Let me know
if logs are needed.
