** Description changed: Hi, we've been running 18.04 (w/ Xubuntu) + 4.15.0-47 kernel for a while now (on Minix Z83-4 devices w/ Intel X5-Z8350 CPUs), which is working fine. After upgrading the kernel to a newer version (> 4.15.0-47), HDMI output is not available anymore, i915 reports an invalid EDID version via dmesg I dropped the full dmesg output on Pastebin: https://pastebin.com/jXTqAzkQ As a start I'm blaming the Linux kernel since booting 4.15.0-47 kernel works just fine. Known faulty kernel versions are: - 4.15.0-58-generic - 4.15.0-59-generic - 5.0.0-25-generic Not sure how to best collect logs and system information for you since I'm not used to debugging black screens. However, SSH access is possible. I am happy to provide more information, if needed. We can also install and test experimental kernel versions. - Note: This happens then attached via a standard HDMI cable as well as - with a HDMI-DVI cable on different monitor setups. + Note: This happens then attached via a standard HDMI cable as well as with a HDMI-DVI cable on different monitor setups. + --- + ProblemType: Bug + ApportVersion: 2.20.9-0ubuntu7.7 + Architecture: amd64 + AudioDevicesInUse: Error: command ['fuser', '-v', '/dev/snd/pcmC1D2p', '/dev/snd/pcmC1D1p', '/dev/snd/pcmC1D0p', '/dev/snd/controlC1', '/dev/snd/by-path', '/dev/snd/pcmC0D1p', '/dev/snd/pcmC0D0c', '/dev/snd/pcmC0D0p', '/dev/snd/controlC0', '/dev/snd/seq', '/dev/snd/timer'] failed with exit code 1: + DistroRelease: Ubuntu 18.04 + InstallationDate: Installed on 2019-01-12 (220 days ago) + InstallationMedia: Xubuntu 18.04.1 LTS "Bionic Beaver" - Release amd64 (20180725) + Lsusb: + Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub + Bus 001 Device 002: ID 046d:c52b Logitech, Inc.
