Fedora 17 & Radeon HD 6450

Hi All,

This is my first post.

I installed Fedora 17 on my box (new to linux) last week. Everything was working fine till I installed new video card ( Gigabyte HD 6450). Now 3.5.0-2.fc17.x86_64.debug #1 SMP works properly but when I boot with 3.5.0-2.fc17.x86_64 in the grub menu, screen starts flickring and does not display anything.

Info about hardware/sw -
