[PLUG] Blank screen after startup

[Dick Steffens]

As mentioned in my most recent post, I've swapped desktop machines. I'm 
mostly successfully using the "newer" installation, ENU-1. I have tried 
running the older installation, ENU-2, but it's not showing the screens 
(two monitors). I watch the initial startup text, then the Xubuntu 
splash screen, then  a "login" screen followed by a blank screen with a 
cursor at the top left of each monitor, so I know the video is working. 
The machine is up and running, since I can connect to it remotely and 
access files. Where do I start to troubleshoot this one?

Thanks.
