I have recently upgraded to 12.04 and all seems okay except adobe flash plugin doesn't work. But several days ago when I installed several update packages and rebooted, X session was unable to start and it automatically switches to console 1 for command line login.

What's frustrating is there's essentially no error messages when I click Alt+F7 to see what's going on with X session. There are a bunch of [ok]'s and the last line seems to be something like starting x font server and it just hang there.

The closest thing to an error is something like stopping system V compatability (\*words I can't remember\*) ... [ok]'.

This is nearly the most frustrating experience I've ever had with Linux in the past 10 years. Can anyone help me?

Try uninstalling the graphics driver and remove xorg.conf:

sudo rm /etc/X11/xorg.conf

Thanks. It turned out it was due to the graphic card driver. X started normally after uninstalling the graphic card driver. – chaos Sep 29 '12 at 17:26
