I had to give a presentation with my laptop recently which has the same issue of having the second screen randomly turn black and then back on again.
Interestingly the presentation went without a hickup. The thing that was different, was that I am having the issue when the secondary screen was connected through HDMi ( with a minidisplay to HDMI adaptor). I wasn't having the issue using a mini display to VGA connector to a projector with a far lower resolution as my secondary screen. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1488719 Title: dmesg shows "[drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied (SDE)!"
