I have installed the Ubuntu phone SDK on a VirtualBox VM running Ubuntu Precise (12.04.2 LTS) as the guest OS. The "guest extensions" have been installed. The guest OS kernel is 32 bit 3.2.0-37 without PAE. I followed the installation instructions for the SDK on http://developer.ubuntu.com, and the installation seemed to go smoothly. However when I attempt to run the demo "Currency Converter" app, qmlscene reports many errors with the form

OpenGL Warning: XGetVisualInfo returned 0 visuals for 0x8db7f98

ultimately followed by the message

Unrecognized OpenGL version

A black box pops up, but nothing is drawn within it. Does anyone know what might be causing this problem?

I had been using a pretty old laptop to run virtualbox. I installed virtualbox on a newer Macbook Pro, and re-installed Ubuntu + Phone SDK. Now the demo app works, so my problem may have been trying to run on too old a machine.

For me , the black box was an error in the code , usually the UI part, look in the debug Qt Creator gives you and make sure you are using QML Scene (just to double check)

As far as I can see on the page of the currency converter app you need Ubuntu 12.10 instead of 12.04 (which I think is quite awkward btw).

I would start with upgrading to 12.10 and then try again..

Good luck!

ps. I am also starting to look into developing an app for the Ubuntu Phone.

That's correct but there were some problems using 12.04. See this thread. – Avedo Feb 18 at 22:37
I upgraded to 12.10. The problem did not go away. – Ken Young Feb 19 at 0:49
