February 8, 20233 yr Hi have two N2s (an N2+ and N2). Both are connected to a Viewsonic 2560x1440 2 HDMI ports monitor where they both work well. One system (N2+) is running Ubuntu 22.04 the other is running Armbian jammy 22.04.01 Kernel 6.0.13 #22.11.2. I have purchased a ATEN CS22H 2 port HDMI/USB KIVM switch. When I connect both systems to the monitor via the KVM I only get a picture from the Ubuntu system. The Armbian system is always black. Can I force the kernel/firmware to be 2560x1440x60hz. I was looking at this post : Regarding forcing the kernel to be a fixed resolution but wasn't sure it was relevant. I am able to connect to the Artmbian system via ssh if I need to. Any suggestions welcome!
February 13, 20233 yr Author I suspect something is missing from the Armbian meson hardware/firmware, because if I boot two copies of Ubuntu then the KVM appears to operate correctly and if I boot two copies of Armbian I see neither system. Edited February 13, 20233 yr by Walter Zambotti
