The patch does not work for me, neither applied to current nightly + unify-flip-modeset (attached dmesg) nor applied to unify-flip-modeset only. NB: My 4770 (HDMI 1080p + HDMI 1440p on IGP) has a new minor issue: Now at boot only one screen shows the tty. If I start X and switch back to tty, both again show the same tty output. Since it's minor, nothing wrong in dmesg and for lack of time I won't test further if it's due to the same cause.</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> </ul> </body> </html>
