I was actually able to reproduce this with 3.14. I tried to reproduce this before with drm-intel-nightly on SNB, IVB and HSW, but failed. Turns out I needed a more recent xorg intel driver to uncover the bug. I bisected the first appearance of the bug to commit 975b9798be77b30cbed485583d0ccb48318708f7 Author: Chris Wilson <<a href="mailto:chris@chris-wilson.co.uk">chris@chris-wilson.co.uk</a>> Date: Wed May 21 08:58:24 2014 +0100 sna: Add support for Present The problem goes away after commit commit 105d478cdd70ac3b38be51c9014b22b7233c241e Author: Chris Wilson <<a href="mailto:chris@chris-wilson.co.uk">chris@chris-wilson.co.uk</a>> Date: Wed Aug 6 09:10:30 2014 +0100 sna: Enable kernel rotation support by default but oddly, after commit b6eeb7a1f7efa591504070b606be655e27e6e9c2 Author: Chris Wilson <<a href="mailto:chris@chris-wilson.co.uk">chris@chris-wilson.co.uk</a>> Date: Wed Nov 5 13:03:41 2014 +0000 Disable DRI3 by default turning the rotation on with xrandr causes a black screen that can be fixed by vt switching away and back to X. Anyway, I haven't looked yet into why the support for the Present extension uncovers the bug, but it seems this bug has been in the kernel for a while.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
