I've been running Fedora 12 with x100e since April. I had written about the Fedora 12 installation here. I decided to install Fedora 13 last week. I think Fedora 13 installation is smoother than Fedora 12 installation. In addition, I've been more satisfied with Fedora 13 performance so far.
Installation consists 3 steps,
1. Put your Fedora 13 DVD to your driver and boot up from DVD drive. Follow the installation steps and install Fedora 13. I performed the installation with external DVD driver. There is no trick in the first step, it's similar to any other simple installation.
2. During the first boot after installation, Fedora 13 freezes. You need to edit kernel parameters as following. At Grub prompt, press 'e' to edit the command before booting, then select the second line and again press 'e' to edit the selected command. Type radeon.modeset=0 at the end of the command, press 'b' to boot up. This is the way to boot up Fedora 13 until display driver installation.
3. Install the ATI display driver and wireless adapter driver.
a. ATI Display Driver link (Notebook Graphics -> Mobility Radeon Series -> Mobility Radeon HD 3xxx Series -> Linux x86).
b. You need to get wireless adapter driver from Realtek website and build it (to install compiler and other development packages as prerequisite). The RTL8192SE driver works well in my system, even wireless adapter is reported as 8172 in lspci output.
Now, you can boot up without radeon.modeset=0.
