Features Passthrough ports: Gigabit Ethernet (RJ45) VGA Microphone Headphone Additional ports: 4 USB ports (1 on the right side, 3 on the back) DisplayPort Battery slot Serial Ultrabay Slim Kensington security hole Pros & Cons Positives: ease up of portability of laptop, digital video output, option for optical drive, allows effective use of second battery Negatives: Reduces cooling capabilities (especially HDD) DisplayPort support in Linux Kernel support for DisplayPort in intel graphic chips using KMS (Kernel Mode Setting) was added by Keith Packard in version 2.6.31. Before that Keith experimented with supporting it in the userspace driver in display-port branch, but he's abandoned this idea as it was impossible to get proper support for some important features like hotplug, suspend/resume etc. See http://bugs.freedesktop.org/show_bug.cgi?id=19995 for details. For Ubuntu Jaunty you can try using driver built from Keith's branch from this PPA, but using kernel 2.6.31 with KMS is probably a better idea.
