What exactly do you mean by not work? (Monitor off, or has signal but black, or flashing no signal?)
Please describe the sequence of events and your observations. (Preferrably with something like xrandr at each point to see what the hardware thinks). E.g. 1. Before suspend. Obs: eDP at native, DP at native 2. Suspend. Obs: everything shuts down 3. Resume. Obs: eDP at native, DP off 4. Restart X. Obs: eDP at native, DP at native. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1269642 Title: X needs a restart after suspend to drive 1920x1200 over displayport Status in “xserver-xorg-video-intel” package in Ubuntu: New Bug description: After suspend, my displayport-connected monitor will (most often) no longer work at the native 1920x1200 resolution. Restarting X fixes it. This is not a new problem, but I always thought I had a wonky cable. I only recently noticed the suspend issue, and only just now the restart thing.
