Using Fedora 20 with kernel 3.13.6-200.fc20.x86_64 I can now use my Lenovo T440s and the ThinkPad Pro Dock and 1 external monitor. However if I connect a second monitor it just gets a mirror of the first external monitor. I can connect the first monitor to VGA or DVI and that works fine.
xrandr output with two monitor connected (same output with only one external monitor): $ xrandr Screen 0: minimum 320 x 200, current 3600 x 1080, maximum 8192 x 8192 eDP1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 309mm x 173mm 1920x1080 60.0*+ 1400x1050 60.0 1280x1024 60.0 1280x960 60.0 1024x768 60.0 800x600 60.3 56.2 640x480 59.9 DP1 disconnected (normal left inverted right x axis y axis) HDMI1 disconnected (normal left inverted right x axis y axis) DP2 connected 1680x1050+1920+0 (normal left inverted right x axis y axis) 459mm x 296mm 1680x1050 60.0*+ 3360x1050 60.0 2560x1024 60.0 1280x1024 75.0 60.0 1440x900 75.0 59.9 1280x960 60.0 1280x800 74.9 59.8 1152x864 75.0 1024x768 75.1 70.1 60.0 832x624 74.6 800x600 72.2 75.0 60.3 56.2 640x480 75.0 72.8 66.7 60.0 720x400 70.1 HDMI2 disconnected (normal left inverted right x axis y axis) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1275794 Title: Lenovo T440s freezes when connected to docking station Status in The Linux Kernel: Fix Released Status in “linux” package in Ubuntu: Triaged Bug description: This bug report looks to be for the same issue: https://bugs.freedesktop.org/show_bug.cgi?id=71267 I came across the above bug report here: https://bbs.archlinux.org/viewtopic.php?pid=1374408 I'm running with a Thinkpad T440s and ultra dock with hdmi<->hdmi. In my case if I dock when hdmi is connected to the dock, the mouse and keyboard freeze once connected. When I undock they unfreeze. If I dock when hdmi is not connected to the dock, the mouse and keyboard don't freeze.
