Mistakenly, the first laptop I tried was an earlier model Dell XPS which did not support DisplayPort 1.2, it supported version 1.1a and so it did not support MST (Intel 4000 Graphics, not 5000 as I reported above).
The second laptop which finally worked was the same Dell XPS but was a newer generation model which did support DisplayPort 1.2. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to 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 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
