Thanks. That's definitely a kernel bug (or a hardware fault, but let's hope a kernel bug).
I can now finally hand this over to the kernel people. Although it might also be helpful if you report the bug upstream here: https://bugzilla.kernel.org/enter_bug.cgi with a new title like: "i915 reports a nonexistent LVDS output (as connected and on)" and the details: grep . /sys/class/drm/*/enabled /sys/class/drm/card0-LVDS-1/enabled:enabled /sys/class/drm/card0-VGA-1/enabled:enabled grep . /sys/class/drm/*/status /sys/class/drm/card0-LVDS-1/status:connected /sys/class/drm/card0-VGA-1/status:connected grep . /sys/class/drm/*/dpms /sys/class/drm/card0-LVDS-1/dpms:On /sys/class/drm/card0-VGA-1/dpms:On then tell us the new bug ID. ** Changed in: linux (Ubuntu) Status: Incomplete => New ** Changed in: linux (Ubuntu) Importance: Undecided => Medium ** Changed in: linux (Ubuntu) Status: New => Triaged -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to 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) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1812359/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
