If you want to use Glamor you'd also want to comment out the intel driver line and uncomment the # Driver "modesetting" line to let the platform-agnostic modesetting DDX manage the Intel displays. I believe the modesetting DDX is the preferred driver going forward, although for HSW both drivers should have support for the platform and it's mostly a distro decision on which one to use. Glamor was initially developed by some Intel folks so during its very early development it was directly part of the Intel DDX, but eventually the glamor code moved into the Xserver itself. Since the Intel DDX has its own specialized acceleration model, it dropped its glamor support in commit 0aa2edbd29c8dd26a5f3748e3875c445ea358a6d Author: Chris Wilson <<a href="mailto:chris@chris-wilson.co.uk">chris@chris-wilson.co.uk</a>> Date: Wed Nov 5 11:56:20 2014 +0000 Remove defunct glamor support leaving uxa, sna, and noaccel as the acceptable acceleration methods.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
