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.
