To: linux-kernel@vger.kernel.org MIME-Version: 1.0 Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7BIT Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org If I have understood things correctly then X/x.org can not provide a flicker free update of the graphics on a display since the linux kernel does not provide a way to synchronize to the vertical retrace of a display. See http://lists.freedesktop.org/archives/xdg/2004-August/004561.html If a person with little previous experience of the linux kernel source tree would like to start on such a feature then how complicated do you believe it is to implement? (days or months of work) Where in the kernel source is a good place to start looking? I'm not on the list so please CC me with your reply.
