Probably worth trying xorg to start with. You need to run reportbug on the affected machine i.e. on HDMI, as it collects various system information as well as your report. Something you might try is to download the latest Knoppix CD, and try that from USB. It's a few years old now, so it may not help, but if it does you can investigate the modules in use and anything else you can find in the X log to see what it's doing that's different. https://www.knopper.net/knoppix-mirrors/index-en.html This is version 9.1, there is a 9.2 but it was only distributed with a magazine, and is probably only slightly different. It is a hardware test and troubleshooting distribution based mainly on Debian unstable, so there is a better chance of getting some useful error messages than with standard Debian. -- Joe
