I had installed ubuntu 11.10 on virtualbox 4.1.8 over windows 7(64-bit, graphics card ATI Radeon HD 5470) as the host. I was trying to run opengl es programs on ubuntu wherein I faced an error during execution:-
OpenGL Warning: Enable 3d acceleration on your VM. Segmentation Fault
I went to the Display options of my VirtualBox and found 3d acceleration to be disabled. I didn't knew that OpenGL required 3d acceleration to be enabled while installing ubuntu setup and missed doing the same. Now I am unable to Enable it from virtualbox and also I am unable to run Opengl exe's on ubuntu. Kindly help on the same.
