Our company just purchased these laptops and we could really use a fix for them. Would you mind sharing the edid files you created to get the displays functioning?

Staff Sergeant, U.S. Army Grovetown, GA Cell: (334)294-4932 "Two things are infinite: the universe and human stupidity; and I'm not completely sure about the former." - Albert Einstein -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1821533 Title: drm fails to accept edid version 2.4 Status in linux-hwe package in Ubuntu: Confirmed Status in xorg-server package in Ubuntu: Confirmed Bug description: Booting very new laptop hardware (ASUS Zenbook UX431FA) from 18.04 usb install (also 18.10, also 19.04 daily) leads to black screen. Adding "nomodeset" to kernel boot parameter gives 800x600 video only and permits installing OS to disk. Applying updates and hardware enablement packages does not solve problem: the system will still only boot with nomodeset kernel option, and X is limited to using fbdev module at 800x600 resolution. The "modesetting" driver appears to be loaded and then unloaded during X startup. Trying to force intel module from xserver-xorg-video-intel by setting up 20-intel.conf file in /usr/share/X11/xorg.conf.d/ does not help. The PCI id for the graphics device appears to be 3ea0 and the place where that might be relevant is the i915 module. This problem occurs with every other Linux release I have tried including Fedora 29, Elementary OS latest, Mint 19.1, Manjaro latest. The one open source OS that I have found where it might be fixed is DragonFlyBSD (see https://bugs.dragonflybsd.org/issues/3167). I have verified that the patch referenced in that bug report does make DragonFlyBSD boot past the video problem which I think is the same problem I experience with every Linux OS I have tried including Ubuntu. guest@guest-ZenBook-UX431FA:~$ lsb_release -rd Description: Ubuntu 18.04.2 LTS Release: 18.04 guest@guest-ZenBook-UX431FA:~$ dpkg -l | grep hwe | egrep "linux|fbdev" ii linux-generic-hwe-18.04 4.18.0.16.66 amd64 Complete Generic Linux kernel and headers ii linux-headers-generic-hwe-18.04 4.18.0.16.66 amd64 Generic Linux kernel headers ii linux-image-generic-hwe-18.04 4.18.0.16.66 amd64 Generic Linux kernel image ii linux-signed-generic-hwe-18.04 4.18.0.16.66 amd64 Complete Signed Generic Linux kernel and headers (dummy transitional package) ii xserver-xorg-video-fbdev-hwe-18.04 1:0.5.0-1ubuntu1~18.04.1 amd64 X.Org X server -- fbdev display driver Expected result: Video at 1920x1080 Actual result: Video limited to 800x600 ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: xorg 1:7.7+19ubuntu7.1 ProcVersionSignature: Ubuntu 4.18.0-16.17~18.04.1-generic 4.18.20 Uname: Linux 4.18.0-16-generic x86_64 ApportVersion: 2.20.9-0ubuntu7.6 Architecture: amd64 BootLog: Error: [Errno 13] Permission denied: '/var/log/boot.log' CompositorRunning: None CurrentDesktop: ubuntu:GNOME Date: Sun Mar 24 10:36:51 2019 DistUpgraded: Fresh install DistroCodename: bionic DistroVariant: ubuntu ExtraDebuggingInterest: Yes, including running git bisection searches GraphicsCard: Intel Corporation Device [8086:3ea0] (prog-if 00 [VGA controller]) Subsystem: ASUSTeK Computer Inc.
