Problem while launching Gazebo
whenever I "roslaunch gazebo_worlds empty_world.launch" the terminal freezes after displaying the following message
"Xlib: extension "GLX" missing on display ":0.0". Insufficient GL support [gazebo-2] process has died [pid 3093, exit code -11]. all processes on machine have died, roslaunch will exit shutting down processing monitor... ... shutting down processing monitor complete done
"
I think my laptop is working on onboard intel graphic card which is causing this problem. Although I have nvidia graphic card already installed I am not sure it is active. I don't know what the problem is.
