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

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,

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

Generally for each version you try you need to install all the packages _except_ the "lowlatency" ones. So: linux-headers-4.19.0-041900_4.19.0-041900.201810221809_all.deb linux-headers-4.19.0-041900-generic_4.19.0-041900.201810221809_amd64.deb

[Bug 1812359] Re: No login screen displayed on a NETBOX nT-435/535 (kernel reports an LVDS output which does not exist as connected and on)

If I consider 4.19, then which of these files I need to install, linux-headers-4.19.0-041900_4.19.0-041900.201810221809_all.deb linux-headers-4.19.0-041900-generic_4.19.0-041900.201810221809_amd64.deb linux-headers-4.19.0-041900-lowlatency_4.19.0-041900.201810221809_amd64.deb

Next, please try some newer kernels (you only have kernel 4.18 with Ubuntu 19.04) from here: https://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D and then use the simple test of: grep . /sys/class/drm/*/enabled to tell us if a newer kernel has changed things. ** Changed in: linux
