Can't launch Carla simulator

Hello,
I’m using the following specs:

Ubuntu 18.04
Nvidia Geforce GTX 950M
8GB RAM

and this is the driver I’m using (the recommended driver):

288422-screenshot-2019-09-26-screenshot-from-2019-09-26-1.png

and I have trouble launching CARLA simulator for the first time:
the command: ./CarlaUE4.sh gives the following result:

288424-screenshot-2019-09-26-screenshot-from-2019-09-26-1.png

and the command: ./CarlaUE4.sh -opengl3 gives this result:

4.22.1-0+++UE4+Release-4.22 517 0
Disabling core dumps.
