Could be, yes. However, I think that I had problems with linux 4.2 as well. 4.3 for sure. I bought this screen (the Eizo) in September and since 4.2 came out in August, this seems likely. I will try it out, though during my next test run tomorrow. > > P.S. How does this relate to <a class="bz_bug_link bz_status_NEW " title="NEW - xorg black screen after monitor power off, AMD r9 270X, aoc u2868pqu, displayport" href="show_bug.cgi?id=90987">bug 90987</a>? Not sure. The difference is, that in this one, only that single screen misbehaves, in <a class="bz_bug_link bz_status_NEW " title="NEW - xorg black screen after monitor power off, AMD r9 270X, aoc u2868pqu, displayport" href="show_bug.cgi?id=90987">bug 90987</a>, all of them do. I can reproduce both individually. Also, while this one is fixable by switching to VT2 and back, <a class="bz_bug_link bz_status_NEW " title="NEW - xorg black screen after monitor power off, AMD r9 270X, aoc u2868pqu, displayport" href="show_bug.cgi?id=90987">bug 90987</a> seems only fixable by restarting X (or at least I didn't find another way yet).</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
