Driver 304.88 boots into a black screen

Problem started today after Ubuntu 12.04 update
Laptop Sony Vaio VPC CW

I do not have a stand-alone monitor, so I connected it to TV with HDMI cable. Upon connecting the login screen appeared both on TV and on laptop display. I can unplug HDMI and use the laptop screen, but upon reboot it becomes blank again.
