Comment 85 for bug 9068

Yes, HAL is dropped in Lucid so the fdi file technique is not relevant anymore. Instead, we have incorporated an xorg.conf.d snippets system, whereby you will configure things like this by dropping a file with the serial mouse snippet (like the ones in comments #12 or #49) into your /etc/X11/xorg.conf.d/ directory. We figure that the fdi file syntax (and the udev syntax that replaced it in earlier versions of lucid) only served to make configuration more obtuse - while editing config files is not a pleasant way to get things working, at least the xorg.conf syntax is reasonably well known and documented pretty heavily on the internet.
