Hello,
Just trying to set up my RPi 4 for Plan 9. It boots into Plan 9 no problem, but at a pretty low resolution with big black borders.

I'm using a 2560x1440 screen connected with HDMI, I run it at 60Hz with other OS on the Rpi.

Could someone please suggest a cmdline.txt config for it? At the moment I've just followed this guide:

Plan 9: Setting up 9front on a Raspberry Pi (luksamuk.codes)

and used:

console=0 user=glenda nobootprompt=local!/dev/sdM0/fs

vgasize just doesn't seem to make any difference on it.

Thanks

Garry
