I have a problem with X, it start correctly only after the command

Code:
$ nvidia-xconfig --prime


every time I reboot, I have to do this and after all works.
If I try to start X without this command I get no screen found error, this the extract from the log

Code:

$ more .local/share/xorg/Xorg.0.log | grep -i ee
