Gazebo blank/black screen (not responding) [closed]

edit

Hello, I am a beginner at ROS and I tried today to run the gazebo for a start via ROS. I use ROS Jade.

I ran at the start :

roscore

then in a new terminal I ran :

 roslaunch gazebo_ros empty_world.launch

The gazebo gui popped up and it shows black/blank screen with a Real Time Factor = 0.0 and it's stuck there no matter how much time I let it to load . The same thing happens when I just run the command :

gazebo

with the exception that then the gui pops a "Does not respond" message .Does this mean that my pc requirements doesn't meet the requirements to run gazebo ?

I am at ubuntu 14.04 LTS (dual installed with Windows) and with the following system overview :
