Open Source Intel Wifi Driver

Intel has created a new Linux Wifi driver project for Intel Wireless cards, "Iwlwifi". This driver is Open Source and no longer requires the Intel daemon to run in addition. This project will support the T61's Wifi Intel 3945ABG network adapter and Intel 4965AGN network adapter.

An automatic migration will occur when upgrading from Ubuntu 7.10 to Ubuntu 8.04. However, there is a caveat to be aware of:

  • The new driver wants to name the interface wlan0 (by default -- you can rename it to anything you want), and requires a different entry in /etc/udev/rules.d/70-persistent-net.rules, which handles the naming of interfaces. Simply edit this file and delete your old entry for the ipw3945 driver, then unload/reload the new driver, or simply reboot. A new entry will automatically be created that is appropriate for the new driver. Here's an example of the lines to delete:
# PCI device 0x8086:0x4227 (ipw3945)
SUBSYSTEM=="net", DRIVERS=="?*", ATTRS{address}=="00:1b:77:a4:0e:2f", NAME="eth1"


If you need to perform a manual migration, the Ubuntu Help Community has written some documentation that will make this very easy to do.

Compiz and XV Playback on Intel GM965/GL960

With Ubuntu 7.10 (Gutsy Gibbon) you currently have to choose between using Compiz and working video playback using XV. On 8.04 (Hardy Heron) alpha 5 you can play videos using XV under compiz, it works right out of the box using the Live-CD.
