Before v3.15.7 all works fine for me. I can plug the second screen to my DELL e-port-dock and the display works as expected. After switching to > v3.15.7 (i.e. v3.16.0) my problems come back. When the system resumes from sleep it needs half a minute to switch on the external display. Same is when switching to console with CTRL+ALT+F1. It seems, that the bug initially fixed with <a href="https://bugs.freedesktop.org/attachment.cgi?id=92231">https://bugs.freedesktop.org/attachment.cgi?id=92231</a> is back again.</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>
