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 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

Okay thanks, Here I found something new in Ubuntu 18.04.2, I thought about to install kernel 4.15.0-43, login screen appeared but resolution issue and not network adapter, neither ethernet nor wireless, so just leave it Then for kernel 4.15.0-45-generic, I've disabled wayland During booting, ubuntu logo appeared (seems like when we set nomodeset), then splash divided into two(ubuntu logo left and right side) and after a minute login screen appeared, but after login, just a wallpaper and nothing like it's freezing, same issue. Please check a log if you can find something new. ** Attachment added: "journalctl -b-1 > 18.04.2_boot_4.15.0-45.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1812359/+attachment/5234958/+files/18.04.2_boot_4.15.0-45.txt -- 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

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
