We don't need any more logs as this bug is fully understood. Although it sounds like you might now be experiencing bug 1795760. Also there are other related bugs to that like bug 1790525 or bug 1795774. Plus there is the original bug 1727356. Those last three are all fixed in 19.04 so please don't use 18.04 any more - it doesn't have enough fixes for your hardware.
The other bug you are experiencing is bug 1760849. So the unresolved bugs you are experiencing in 19.04 are bug 1812359, bug 1760849 and maybe 1795760. But to avoid confusion we should really only talk about bug 1812359 here. And you should only use Ubuntu 19.04 because 18.04 contains a little too many of those bugs. If you would like to speed up the resolution of this problem (bug 1812359) then please follow the steps in comment #81. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1812359 Title: No login screen displayed on a NETBOX nT-435/535 (kernel reports an LVDS output which does not exist as connected and on) Status in linux package in Ubuntu: Triaged Bug description: On a machine with only one display (VGA), the kernel is reporting two: grep . /sys/class/drm/*/enabled /sys/class/drm/card0-LVDS-1/enabled:enabled /sys/class/drm/card0-VGA-1/enabled:enabled ls /sys/class/drm card0 card0-LVDS-1 card0-VGA-1 renderD128 version grep . /sys/class/drm/*/dpms /sys/class/drm/card0-LVDS-1/dpms:On /sys/class/drm/card0-VGA-1/dpms:On which then triggers bug 1760849 and the login screen is never visible. --- $ dpkg -s mutter Package: mutter Status: install ok installed Priority: optional Section: x11 Installed-Size: 101 Maintainer: Ubuntu Developers <ubuntu-devel-disc...@lists.ubuntu.com> Architecture: amd64 Version: 3.28.3-2~ubuntu18.04.2 Provides: x-window-manager Depends: libc6 (>= 2.4), libglib2.0-0 (>= 2.53.2), libmutter-2-0 (>= 3.28.2), libx11-6, libxcomposite1 (>= 1:0.3-1), mutter-common (>= 3.28.3-2~ubuntu18.04.2), gnome-settings-daemon, gsettings-desktop-schemas (>= 3.21.4), zenity Suggests: gnome-control-center (>= 1:3.25.2), xdg-user-dirs Description: lightweight GTK+ window manager Mutter is a small window manager, using GTK+ and Clutter to do everything. .
