Vincent, what you could do is to take a look at this instruction: https://01.org/linuxgraphics/node/358
Based on this you could: sudo add-apt-repository ppa:dgadomski/linux-mst sudo add-apt-repository ppa:xorg-edgers/ppa sudo apt-get update sudo apt-get install linux-image-3.16.0-19-generic # this will install the patched kernel for trusty sudo apt-get install xserver-xorg-video-intel # this should get you the xorg-edgers intel driver with all the dependencies needed Now you can reboot and verify with xrandr (like in the linked instruction) whether your displays are available or not. Please make sure you have ppa-purge available (sudo apt-get install ppa-purge) so you will be able to revert it later if anything goes wrong with: sudo ppa-purge ppa:dgadomski/linux-mst ppa:xorg-edgers/ppa -- 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/ubuntu/+source/xserver-xorg-video-intel/+bug/1104230/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
