Yes it does have hybrid graphics. I also use an external GPU. This occurs with or without the EGPU plugged in.
However, it may be that there was a problem in that specific version of SDDM in that particular daily build. Somehow, someway installing the Ubuntu Gnome desktop system and gdm2 fixed it. Then I did a full upgrade a couple days ago and got a new version of sddm, switched to that and that seems to have fixed it. The real problem is that a new user when confronted with a utterly BLACK screen won't know to Ctrl alt f6 into a terminal and do things from there. That sort of thing is a typical "why Linux will always be for geeks" moment. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1765923 Title: Nvidia driver leads to black screen on bionic 18.04 SDDM LightDM bug?
