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 Ubuntu Desktop Bugs, 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 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-settings-daemon/+bug/1730093/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
