Ubuntu and BitCurator log in

[Matt Gorzalski]

I can't log back into Ubuntu to get me back to the BitCurator desktop.  Last week I updated Ubuntu (like a Windows update) and tried to get back into BitCurator through Virtual Box but I get stuck at a log in screen like this: http://i1-news.softpedia-static.com/images/news2/Ubuntu-12-04-LTS-Will-Get-Chameleonic-Login-Screen-2.jpg.  I select BitCurator and enter bcadmin as the password and it doesn't work.  Help?

Hi Matt,

Can you log in on a regular terminal? Press Control + Alt + F3 which will take you to a login prompt. Enter "bcadmin" for the user and "bcadmin" for the password and see what happens.

I did that and it brought me to the attached screen shot.

Okay, well the good news is that you can log into the system just fine. I would go back to the GUI login screen (press Control + Alt + F7) and make sure that the "BitCurator" user is available and selected, not the "Guest Session", and try to log in again with the "bcadmin" password. If that doesn't work, you can get to the GUI interface in a roundabout way by once again logging in via the terminal and then typing "sudo restart lightdm" at the command prompt. This should launch the regular BitCurator interface. Once here I would backup your work onto the host OS and create a new BitCurator VM. Here's a link on how to create a shared directory between BiCurator and your host OS: http://wiki.bitcurator.net/index.php?title=Share_files_to_and_from_the_BitCurator_environment

After playing with it some more and having some help, I discovered that the Ubuntu (Default) and GNOME Flashback (Compiz) crash upon opening and kick me back to the login screen.  But I can log in just fine using GNOME Flashback (Metacity).  Before I'm pretty sure we used Ubuntu (Default).  Has anyone experienced that before?

Nope, this is the first time I've heard of this issue. However, as a general rule I strongly recommend not updating BitCurator via the Ubuntu Software Updater. On more than one occasion Ubuntu updates have overwritten BitCurator customizations.

Hi Porter,

Do you also recommend against updating software elements within bitcurator, or just the OS as a whole?

On a slightly tangential note, I was wondering if any of the "additional software" one is given the option to download when installing BC (or any version of Ubuntu) are either recommended or necessary for BC to function properly.

Thanks,

Christie

You should be okay updating specific applications so long as they're not part of the digital forensics tools in BitCurator or major system components. The problem with the updater is that if you hit the "update all" button, you could be updating anything as trivial as a web plugin or something as significant as the Linux kernel, so it's best not to use it. Or, rather, to only use it to update applications you know you need to update and can back out of.

Regarding your second question, I would say that is totally up to the individual user. However, keep in mind that if you're installing BitCurator from the ISO and not just using the VirtualBox VM, none of your choices during the install process matter after disk partitioning. You get the customized BitCurator version of Linux no matter what you select (that's why the username and password are always "bcadmin"). So if there were additional software apps that you wanted, you would need to install them after the OS installation process.

Great, thanks for the clarifications, Porter!
