Cursor not moving

Hi,


I bought a new laptop, a MSIGT62VR with a GTX 1070.


I installed ubuntu 16.10 and everything work fine except one thing: my cursor !
It doesn't move from the left upper corner.. I can move the mouse virtually, I can click everywhere but the cursor is not moving..


I tried a lot of solutions !
Some says that is due to the nvidia driver... That why I post here.


I tried to install the 369 driver from the PPA and the 375 but after that, I can't boot.. It is blocked on the clean /sda5 line...
I tried some other tricks but anything worked....


It is maybe important to say that it is a fresh installation in dual boot with windows 10..


I'm out of idea !
Please help me ! It is really frustrating !
