I have a Toshiba Satellite e205 dual booting Ubuntu and Windows 7. I just upgraded to 12.04 and I've been having an issue with the OS hanging on shutdown. It will close all the windows and go to the splash screen and then hang there indefinitely.
At first I thought the problem was related to Dropbox - if I turned Dropbox off or didn't connect to the internet it would shut down fine. I uninstalled Dropbox and that helped, but it still will occasionally exhibits the same problem. It seems anecdotally as if the longer I have the computer running the more likely it is to fail on shut-down.
Any ideas on what might be happening or how to troubleshoot would be great. Thanks!
