In several questions on this site, I saw that Ubuntu 15.04 would have support for Displayport daisychaining/MST. I have a two monitors that have Displayport in and out, indicating that they can be connected together. When connected to my laptop, both monitors work, but only one display appears, and that display is mirrored over both monitors.
I am using integrated Intel graphics on a Dell XPS 13. I had to install Xubuntu over a Windows installation.
Any ideas about what I have to do to get Xubuntu to detect the daisychained monitor?
