I cannot actually test the whole chain as I'm faking having the monitor, but you'll hopefully be able to test it. So you need in addition of the 2 kernel patches already mentioned: - This patch to the X server - The master branch of the DDX driver (a bug fixed in the UXA part of the driver) <a href="http://cgit.freedesktop.org/xorg/driver/xf86-video-intel">http://cgit.freedesktop.org/xorg/driver/xf86-video-intel</a>. Or you can just cherry-pick "uxa/display: Keep the EDID blob around for the lifetime of an output"</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
