Upgrading from 12.04 to 14.04 last night and everthing was chugging along nicely until I tried to open a browser. The screen went to black for a few seconds and then came back to the user login screen (as if I was changing users). There is only one user account on this machine, so I entered my password and up came the ubuntu 14.04 screen at a lower resolution.
The hard drive light continued to blink, so I was hopeful that the upgrade would continue even though I could no longer see the desktop with update screen, but it stopped after about 30 seconds. I can move the cursor around but get no response from keyboard entries.
So what should I do now? Is there a chance that I could log back in to the original desktop and continue the installation? As I remember, it was maybe a third of the way through the upgrade according to the bar at the bottom of the upgrade window (it had just asked me if it could replace settings for "Fuse").
Or should I restart the computer and hope for the best?
Any guidance would be truly appreciated!
