Same for me with a Lenovo W510 in dock, two external monitors and Ubuntu GNOME 16.04 LTS.
After waking up my notebook two or three times I am finally able to login via GDM and use my system as normal, but as soon as I switch to one of the ttys my laptop suspends again. Btw: I don't know if this is relevant, but for the sake of completeness I want to mention that hwinfo --monitors gives no output at all! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1450009 Title: [HP, Dell notebooks] suspends on closed lid, does not recognized external monitors/dock To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1450009/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
