Yesterday, I did the automated software update for ubuntu gnome 14.04, and the machine has stopped booting since then. The upgrade gives out a new kernel which is 3.13.0-53-generic from the previous 188.8.131.52-generic
All I get is the infinite wait at the gnome boot screen. I am using a Thinkpad E430, This is the first time I encountered such an error, If any furthur info (logs etc.) are required, I can provide the same.
update: does this help??
