Just a heads up, Nvidia 535.54.03-1 broke my system
Rarely something breaks my system (other than me messing with it), but this update was one of them. At first I thought it was the kernel upgrade that also came by today, but downgrading this pkg to 530 ~ made X and gdm work again
I have been using the Frogging-Family Nvidia PKGBUILD for ages now. Easiest way I have seen to stay on the latest versions of the proprietary drivers with the least amount of headaches.
