The output of my bug-log is below:

There is also another one attempt to reinstall driver, cuda, remove xorg.conf file …select-prime nvidia etc…I tried all solutions I have seen however for some reason does not work:

Well It seems that Nvidia is working along with Intel graphic card. However I do not understand why I cannot access nvidia-settings?
Can you help me please?

Please run nvidia-bug-report.sh as root and attach the resulting nvidia-bug-report.log.gz file to your post.

Thanks I have started from scratch and now the simulator is working
