Fedora19 scrambled login screen

The Fedora19 LiveCD functioned correctly. The LiveCD installed to the hard drive correctly. After booting from the hard drive the login screen looks and functions correctly. After updating to kernel 3.11.2-201.fc19x86_64, the login screen is distorted with large shaded triangles. After logging in, the first screen is also scrabbled. If I bring up the shell Terminal, everything straightens up.

What could be causing this?

I've seen similar (although maybe not identical) behaviour recently. On a brand new AMD FM2 system with integrated ATI graphics, until I got wonky graphics until I put the kmod-catalyst package from rpmfusion-nonfree. It sounds most like what you're describing.

I also saw this on an older nVidia chipset laptop. The video chip it used is so old that it was no longer supported by the standard kmod-nvidia module. It was only resolved by putting on the video driver that matched the chipset.

To solve this, then, I can only suggest that you find out which video chipset your computer user, then investigate which kernel module you need to make it work. Then install the relevant one from the rpmfusion-nonfree repository.
