Just to make sure, I again repeated the sequence of events outlined above on the stock 17.10 kernel:
Linux magpie 4.13.0-16-generic #19-Ubuntu SMP Wed Oct 11 18:35:14 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux The behavior is identical to that reported above. One minor elaboration: when I open the control panel->Devices->Displays with the lid action set to "ignore", I have to toggle the external monitor, even if it is currently selected, in order to prevent the lid close from blanking the display. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-settings-daemon in Ubuntu. https://bugs.launchpad.net/bugs/1730093 Title: Gnome suspends or blanks external monitor when laptop is docked Status in gnome-settings-daemon package in Ubuntu: New Bug description: In the default configuration, resuming my T440s on the Lenovo ultradock results in not detecting the external monitor followed by a suspend. If I open the lid while on the dock, gnome detects the external monitor and blanks the laptop display. Then, closing the lid results in suspend. As a work around, using tweak tool (or UPower) to ignore the lid, does prevent the suspend. But it is not automatic; each time, one must bring up the gnome control panel->devices->displays and manually select single display. Then the lid may be closed without suspend. This worked fine in 17.04, so I'm hoping that the provides enough clues that this can be fixed easily. Thanks! I am enjoying the new Ubuntu 17.10 generally, but this situation is annoying.

Same behavior on stock 17.10 kernel.
