[Cherep <acherep@xxxxxxx>]

Hi all,

I've repeated on my Lenovo Z360 the test Daniel did. The results are below. 

I have just one question:
after I turn NVIDIA off, I can type something in Terminal but I can't move the mouse - everything becomes frozen :( how I can deal with it?

Thank you!
Cherep
