Xorg-server 1.9 Upgrade Guide
Xorg can detect input devices using udev, removing its HAL support.
Users who used HAL before need to migrate to udev.
Migrating from xorg-server 1.8
The primary difference is that the deprecated HAL support has now been removed
in favor of udev. If you already used udev before, then no action is necessary.
If you used HAL with xorg-server-1.8 then read on.
Migrating from xorg-server 1.7 or 1.8 with HAL
Enabling udev just requires building xorg-server with USE="udev".
Systems which worked fine with the default HAL fdi will not need special
configuration. If you created custom fdi files, then refer to the Xorg-server 1.8 Upgrade Guide
how to migrate your configuration to udev.
