i am new to linux...

running virtualbox>>ubuntu i have amd 6950 graphics card on windows10.

the problem is only when i use 3d acceleration in virtualbox.

with 3d acceleration activated .....

.... < $ roslaunch gazeboros emptyworld.launch > works..

.. the willowgarage_world.launch also works....i can place 3d shapes and pan around with mouse...

but the problem is < roslaunch gazeboros shapesworld.launch > or mudworld or rubbleworld doesn't work.

< $ roslaunch huskygazebo huskyempty_world.launch > doesnt work...

< $ roslaunch huskygazebo huskyemptyworld.launch worldname:=worlds/willowgarage.world > doesn't work

when i say doesn't work.. i mean the gazebo runs but the graphics 3d window is all black....i can see the menu bars and fps is also showing about 60fps, but the visual display portion is all black .... any ideas...thank you
