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?
