how-to install?
If you have an HD4xxx series card, 12.4 is the newest driver to support it. This won't work with X version 1.12 (the one packaged with Fedora 17). To downgrade to X version 1.11, use the following commands (as root).
Note: I'm assuming x86_64
IMPORTANT: I'd highly recommend going down to runlevel 3 first. You can do this using the following command in one of the text consoles (<CTRL> + <ALT> + <Fx> where x is 1-9, just try them until you get to a console)
systemctl isolate runlevel3.target
Commands for downgrading X:
yum erase xorg-x11-drv-intel
yum --releasever=16 install libxcb* xcb-util startup-notification*
yum --releasever=16 downgrade *xcb* xorg*
You may also need libxcb.i686 from the Fedora 16 release. The intel driver has additional dependencies, and those with AMD/ATi cards don't need it anyway.
