I'm having the same issue (mostly) with Ubuntu 19.04. I'm using: WM: i3 DM: LightDM Dock: Caldigit TS3 Plus with 2 monitors connected through DP daisy chain
If I suspend after undocking, when I resume the screen is blank, but the laptop is not frozen because I can still type in commands and stuff. I can hit my configured shortcut to reboot and it does. For me, attempting to switch to a different TTY does not work. However, when it goes into the reboot sequence, the Ubuntu screen does show up before shutting down. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gdm3 in Ubuntu. https://bugs.launchpad.net/bugs/1802574 Title: laptop screen never comes on after undock / sleep / open of laptop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1802574/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
