If you know how you could try and go back to the 260.19.06 nvidia driver - see if that makes it work again for you.
I have filed a bug with NVidia - but it hasn't shown up on their system yet.
I can't do that just because on my system the display "freeze" just before the login dialog with the 260.19.06 driver
and if I try the xserver nv driver, Sketchup shows up an error : ChoosePixelFormat
