I have a machine with Ubuntu 18.04 with a Nvidia card in it and am attempting to connect it to a monitor through a HDMI KVM. When the machine powers on I see the normal BIOs screens and the Ubuntu loading splash screen, but once it gets past that nothing is displayed on the monitor. When connecting directly to the monitor everything seems to work and I get the normal login screen and can use the machine as normal.
I assume that the problem has something to do with the negotiation process between the nvidia driver and the monitor but I have no idea where to even start looking. Are there any suggestions on how to troubleshoot this? I’ve included bug reports for when plugged into the monitor directly and then again when plugged into the KVM if this is helpful.nvidia-bug-report_notworking_through_kvm.log.gz (339.4 KB) nvidia-bug-report_working_direct_to_monitor.log.gz (322.0 KB)
