The multiseat computer configuration has been carried out again on a new computer with the Ubuntu 7.04 release.
The main difference in this installation is that a brand new computer has been used. The computer was equiped with a PCI-Express card (nVidia 6600), instead of using an AGP card as we did in our first installation.
The big news are that the problems related to keyboard configuration seem to be solved. The page related to gdm and xkb has been updated with instructions on how to solve the keyboard missconfiguration problem reported by several users.
Update (20080114): Pics added. The pics were taken on 20070518
