Subject: Forcing display size on Pi4
Date: Tue, 17 Dec 2019 13:05:33 -0800	[thread overview]
Message-ID: <f4e5442d5afb8586@orthanc.ca> (raw)

I have a 2K display that Plan9 forces to 1920x1080 resolution.
Poking around 9/bcm/screen.c indicates that setting vgasize=WxHxD
should force the size, but adding a suitable entry in cmdline.txt
just gives me a blank display.

Before I dig deeper, is this expected to work?  If it is I'll start
adding some kernel prints and try to find out what's not working.
