I think there is issues in handling such case in gnome-shell/bionic itself. With an Intel card only platform, one may login via gdm displayed on the external monitor. But when logged in, the built-in display will have the content of a second one, and the external monitor will be blank. Then if you unplug HDMI and replug in, the external monitor will have the content of a second one, but the built-in display will be off.
So there might be an hardware/nvidia/i915 issue in `edp_panel_vdd_on()`, but upgrade the system to Disco/Eoan is still a must to receive new fixes for related behaviors. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1801359 Title: Notebook lid blank after booting with lid closed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1801359/+subscriptions -- ubuntu-bugs mailing list email@example.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
