In almost all cases you want DRM, not X11.  The X11 option requires an active X session, and is not suitable for headless operation.  The only reason to use X11 is for local rendering, but this is not well tested or optimized since the focus is on server use cases.  In future releases (including the new R3 beta) there have been some updates to the stack so this question is no longer necessary in the installer.  

For kernel levels, today requirements are quite specific.  There are only a few supported configurations.  More info is in the release notes and install guides.

For 4th Generation Core/HSW:
  * Ubuntu Server 12.04 LTS: 3.8.0-23-generic (via apt-get)
  * SUSE Linux Enterprise Server (SLES) 11, service pack 3: 3.0.76-0.11-default

It is well understood that this needs to become more flexible, with better support for more advanced kernels, building your own i915 module, etc.  This is a work in progress, so please stay tuned.

Jeffrey,

how to get the R3 Beta for Linux Servers? I have purchased the Linux Server SDK, but the R3 Beta version is not available in the download options.

Thanks, Artem

Sorry for the delay in getting the release updated.  Checking on options to get this out ASAP.  I'll update as soon as there is news.
