Gray box instead of displaying video

[Thiago Padilha]

Hi

I can't get lightspark to work on my virtualbox running 12.04 ubuntu(windows host) all I can see is a gray box. I followed the instructions here: http://sourceforge.net/apps/trac/lightspark/wiki/Troubleshooting (first section: testing your installation) but it also didn't work. In the console output I saw this:

I must warn my environment is not so common:

- I use a minimal command-line install of ubuntu so I don't have the usual ubuntu desktop packages installed
- I installed only a few X apps in the VM and display them via Cygwin-X running in my windows system.
- I use windows version of pulseaudio to play sound from the VM(which runs in the background)

I alot of X apps works perfectly in my setup, like adobe flash and 3d games like armagetronad so I don't think it is a matter of configuring my system.

I have tried the both ppa version(7.1)and the packaged ubuntu version(5.5) but neither worked. I didn't try to use in a full ubuntu desktop but if I were to guess I would say some dependency is missing, maybe something that is always present in ubuntu desktop and wasn't declared as a package dependency.

This error

ERROR: Exception in RenderThread, stopping rendering: Could not compile fragment shader

indicates that the problem is lack of or insufficient OpenGL support. Lightspark uses OpenGL for rendering.
