please help me i can't click on interface elements

ok, so i just installed ubuntu and when i boot into it. i can't click on things (like my icons on the left) but when i run "compiz --replace &" and "unity --reset" in the terminal and log out and in, it works. but i dont want to do that every time i start up my computer. fresh install didnt work.

my specs:

i7-4790

gigabyte Z97-D3H motherboard

8gb ram

gtx 970

128gb samsung 840 pro

1TB WD blue

and my nvidia drivers are version 346.59 from nvidia-346-updates. i am just using unity, and didnt change anything other than numix circle theme (the problem started when i booted for the first time into ubuntu, not after any program install)

edit1: i am using ubuntu 15.04 installing 14.04/14.10 didnt change anything

edit2: i install nvidia-cuda-toolkit that also didnt change anything

edit3:
