I have Ubuntu 12.04, which has been working great for me since I installed it a year ago.

Yesterday I ran the updates that update manager recommended. (Last time I ran updates before was about a week ago).

After the updates were installed, it asked me to reboot. So I rebooted it, and then it stopped at login prompt (as a command line, with no windows).

I logged in and tried to manually start the windows manager, and the screen went blank, and stayed blank I waited several minutes, and then turned it off.

How can I figure out what is the problem? Which logs should I check?

Will final version of 12.04 use the power management changes found in kernel 3.3

I have seen in some version of Ubuntu that instead of making a huge change to update to the latest kernel, they take some of the good stuff out of it, for the sake of stability and put it on a previous version. In this case, kernel 3.3 has seen some very good power management enhancements that are… >>> More
