I installed 13.04 as a virtual machine using VirtualBox from Oracle. When it was done doing the install, it says that it needs a reboot. After the reboot, I got this message:

Sorry Ubuntu 13.04 has experienced an internal error /usr/bin/compiz

I'm not sure what it means and how to resolve it.

  • Welcome to Ask Ubuntu! We need more hardware information to help you, can you look at this question and then edit your question adding the information. Also, have you checked the BIOS for settings relating to virtualization?

    After a fresh install it is alwasy a good idea to update your guest OS by running sudo apt-get update && sudo apt-get dist-upgrade there. This may get bug fixed.

    It's a virtual machine that I'm running on VirtualBox 4.2.16. The 13.04 Ubuntu that I installed is 32bit. The host machine is Win 7, 64bit with 8GB ram and about 600GB free disk space. It's an HP laptop with Intel Core i5. Using nvidia geforce gt 630m 1gb. When I start the virtual machine (Ubuntu), I get the login page. After I put my login info, I get a black screen. Eventually the error message comes up. I clicked Continue then I'm back to a black screen. Just a mouse cursor and nothing else.

It just means there's been a problem with compiz, which is the window manager on Ubuntu. If you don't experience any problems, then it has corrected itself. However, you can file bugs if you want to tell developers what happened so that they can fix it.

If your desktop is working properly, you don't have to worry about it. But you'll probably want to install Virtual Box Guest Additions, which will provide drivers for your graphics and other things.

    +1 You definitely want to install the guest additions, especially if you are seeing problems.

I had the same problem. I solved it by selecting into VirtualBox properties "Activate 2D acceleration". After that the desktop is working.
