Comment 24 for bug 1323967

Yung Shen and Po-Hsu Lin - the info that you both posted shows that you are both using Mesa 10.1.3. As per comment #11, you need Mesa 10.2. Ubuntu 14.10 "Utopic Unicorn" currently has mesa 10.3.0-0ubuntu3 and mesa 10.3.2-0ubuntu0.1 is currently in utopic-proposed.

I could not find any mention in the upstream changelogs of the new hardware support being backported to mesa 10.1.x point releases, nor is there any mention of it in the Ubuntu mesa changelog for Trusty at https://launchpad.net/ubuntu/+source/mesa/+changelog

Mesa 10.3 or 10.3.2 will probably be included in Ubuntu "Trusty Tahr " 14.04.2, which is scheduled for release on 5th February 2015.
