DisplayPort support in Linux
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.
Support for DisplayPort is developed by Keith Packard in display-port branch and will be hopefully merged to master before 2.8 release. This freedesktop's bugzilla issue tracks this work.
Keith is also working on improving the support on the kernel side in his private branch. According to this article it will be hopefully included in 2.6.31 release.
Meanwhile several people reported to successfully build and use the driver from Keith's display-port branch. For Ubuntu Jaunty you can try this PPA.
