Thank you for your quick reply. Yes, I am using an HDMI-HDMI cable with no adapters. I have tried bot booting with the external monitor already attached and attaching/reattaching it later. No SVGA plugs. The monitor is an Acer S230HL monitor. I am using the nouveau driver and inxi reports the presence of both Intel UHD Graphics 620 and Nvidia GM108M (GeForce 940MX).
