I've got that in progress. In the meantime, I realized there was a newer kernel+driver from yours and the xorg-edgers PPAs, so I did that upgrade, and now unity-control-center only sees one external monitor, with the second being treated as a mirror of the first. This is using: 3.16.0-28-generic xserver-xorg-video-intel 2:2.99.916+git20141210.04a09d35-0ubuntu0sarvatt
Here's some drm.debug logspam which may or may not be useful. I'm in the process of updating to the mainline 3.17 - I'll report back soon with results. ** Attachment added: "debug.txt" https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1104230/+attachment/4278747/+files/debug.txt -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1104230 Title: DisplayPort 1.2 MST support is missing in the Intel driver To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/1104230/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
