Most Linux distributions still use 2.6.x version of Intel driver which does not have support for DisplayPort. This means that you will be able to use it only in low graphics mode with vesa driver.<br>

Kernel support for DisplayPort in intel graphic chips using KMS (Kernel Mode Setting) was added by Keith Packard in version 2.6.31.

Support for DisplayPort is developed by Keith Packard in [http://cgit.freedesktop.org/xorg/driver/xf86-video-intel/log/?h=display-port display-port branch] and will be hopefully merged to master before 2.8 release. [http://bugs.freedesktop.org/show_bug.cgi?id=19995 This freedesktop's bugzilla issue] tracks this work. Keith is also working on improving the support on the kernel side in his [http://cgit.freedesktop.org/~keithp/drm-intel/ private branch]. According to [http://www.phoronix.com/scan.php?page=news_item&px=NzMwMA this article] it will be hopefully included in 2.6.31 release.<br>

Meanwhile several people reported to successfully build and use the driver from Keith's display-port branch. For Ubuntu Jaunty you can try [https://launchpad.net/~morgwai/+archive/intel-displayport this PPA].

Before that Keith experimented with supporting it in the userspace driver in [http://cgit.freedesktop.org/xorg/driver/xf86-video-intel/log/?h=display-port 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.<br>

For Ubuntu Jaunty you can try using driver built from Keith's branch from [https://launchpad.net/~morgwai/+archive/intel-displayport this PPA], but using kernel 2.6.31 with KMS is probably a better idea.

Lenovo X200 UltraBase

Here is some basic info about X200 UltraBase: portable dock for the X200-series ThinkPads (X200, X200s, X200 Tablet) providing extra ports (notably DisplayPort), Ultrabay Slim slot and an additional battery slot.

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.
