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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1275794 Title: Lenovo T440s freezes when connected to docking station To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1275794/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
