My first time trying to use Ubuntu. I clean installed the Ubuntu 12.10-beta2 on an old Dell Dimension 4600 today. Install seemed to go fine, but after restarting and entering the requested passwords I'm taken to a purple screen with no panels, launchers or anything else--just a purple screen. I'm able to access the terminal from the screen with ctrl-alt-t, but I'm not sure at this point in my Linux training how to search for errors. Also have no Internet connection (I'm typing this on a mac), but I'll have to deal with that later. Would appreciate any suggestions.
Those are the symptoms of bug 1039155, which was marked fixed by an update in Quantal today. Update and try it.
Update: the user who filed that bug has written: "Re-opening the bug as it is not fixed for me." So this looks up in the air for now.
For any errors in ubuntu, usually this command would help pin point if there was a major error. It is a way of viewing a snippet of your error log.
Also since you can bring up the terminal, my guess is, unity must have an issue. I recommend you run the following commands
first open the software properties window,
go to other software TAB, and enable the Cannonical Partners and the source code, and the independent, and their source code. Also in the Ubuntu Software TAB, enable all the following sources,
If the issue is that you've installed a buggy package, it will upgrade your system, with the latest fixes. Ubuntu repositories talks about each, and what is their role. Since you running beta anyways, i'll recommend it. But you can read up and see if you want to keep them enabled after the final release. Close the window
If error persist, we have to reset unity, from command line
Reset Compiz and Unity
