I can go to 16.04, and my HDMI screen stops working (I have HDMI and display port on my Intel NUC); if I boot back to 14.x, it works great. More interestingly: it appears to be kernel related, because if I boot the 14.x kernel in 16.04, it's still happy. 16.10 seems to work most of the time, though I still had issues a day or two ago.</p> <p>-Ken</p> <p> </p> <p>On 2016-10-28 14:53, Kevin O'Gorman wrote:</p> <blockquote type="cite" style="padding: 0 0.4em; border-left: #1010ff 2px solid; margin: 0"> <div dir="ltr">I've had lots of problems with multiple monitors starting about 16.04. I have three. I can boot into 14.04 where there is no problem, or 16.04 where it's hard to get any monitors to work after they shut off from inactivity. There are other problems as well. This doesn't seem exactly what you're seeing, but could be another symptom of a similar underyling thing.</div> <div class="gmail_extra"><br /> <div class="gmail_quote">On Fri, Oct 28, 2016 at 7:30 AM, Liam Proven <span><<a href="mailto:lproven@gmail.com">lproven@gmail.com</a>></span> wrote:<br /> <blockquote class="gmail_quote" style="margin: 0 0 0 .8ex; border-left: 1px #ccc solid; padding-left: 1ex;">Anyone noticed this?<br /> <br /> I have a spare recovery install of 64-bit Ubuntu on my Mac mini's<br /> external Firewire backup drive. (Normally the machine runs Mac OS X<br /> 10.11.)<br /> <br /> It was a copy of 16.04 -- I reinstalled over the top of a copy of the<br /> OS from my old (BIOS-era) laptop, to "Macify" it and bring it back to<br /> life.<br /> <br /> Worked perfectly. Sound, wired and wireless networking, dual head (one<br /> HDMI + one Displayport), everything. The dual head uses the on-chip<br /> Intel HD 3000 GPU.<br /> <br /> A few days ago I updated the laptop the image came from to 16.10. No<br /> problems at all except with Nemo, so I removed Nemo.<br /> <br /> So last night I updated the Mac to 16.10.<br /> <br /> And now my Displayport monitor is dead. It's detected but there is no<br /> image. Blank, dead.<br /> <br /> Anyone else seen anything like that?<br /> <span class="HOEnZb"><span style="color: #888888;"><br /> --<br /> Liam Proven • Profile: <a href="http://lproven.livejournal.com/profile">http://lproven.livejournal.<wbr />com/profile</a><br /> Email: <a href="mailto:lproven@cix.co.uk">lproven@cix.co.uk</a> • GMail/Twitter/Facebook/Flickr: lproven<br /> Skype/MSN: <a href="mailto:lproven@hotmail.com">lproven@hotmail.com</a> • LinkedIn/AIM/Yahoo: liamproven<br /> Cell/Mobiles: <a href="tel:%2B44%207939-087884">+44 7939-087884</a> (UK) • <a href="tel:%2B420%20702%20829%20053">+420 702 829 053</a> (ČR)<br /> <br /> --<br /> ubuntu-users mailing list<br /> <a href="mailto:ubuntu-users@lists.ubuntu.com">ubuntu-users@lists.ubuntu.com</a><br /> Modify settings or unsubscribe at: <a href="https://lists.ubuntu.com/mailman/listinfo/ubuntu-users">https://lists.ubuntu.com/<wbr />mailman/listinfo/ubuntu-users</a><br /> </span></span></blockquote> </div> <br /><br clear="all" /><br />-- <br /> <div class="gmail_signature"> <div dir="ltr"> <div>Kevin O'Gorman</div> #define QUESTION ((bb) || (!bb)) /* Shakespeare */<br /><br /> <div><span style="line-height: normal; font-variant: normal; font-size: 10pt; font-style: normal; font-weight: normal;"><span style="line-height: normal; font-variant: normal; font-size: 10pt; font-style: normal; font-weight: normal;"></span></span> <table border="0" width="448" cellspacing="0" cellpadding="0"> <tbody> <tr> <td width="25"><img alt="" width="25" height="21" /></td> <td width="423"><span style="font-family: Verdana,Geneva,sans-serif; color: #009900; margin-left: 5px; font-size: 10px;">Please consider the environment before printing this email.</span></td> </tr> </tbody> </table> </div> </div> </div> </div> <br /> <div class="pre" style="margin: 0; padding: 0; font-family: monospace"> </div> </blockquote> <p> </p> <div> </div> </body></html>
