However in my case it was every second connection leaving external displays blank, the subsequent connection usually fixed the issue. I've fixed it in Xserver, which now works for me, however haven't yet pushed the changed for XServer. Can you try xrandr --output (your output name) --crtc (some number here). If that helps - then this is probably a duplicate of 106250.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
