Switching between HDMI and internal display on A311D

Hello! Bumping this thread because I wonder if anyone is currently able to switch to HDMI on a311d and back to the internal display on Pocket Reform.

This works for me to switch to an external HDMI display (on Pocket Reform):

swaymsg output DSI-1 disable
swaymsg output HDMI-A-1 enable
swaymsg output HDMI-A-1 modeline 148.50 1920 2448 2492\
                                 2640 1080 1084 1089\
                                 1125 +hsync +vsync

However, none of the following allow me to switch back:

swaymsg output HDMI-A-1 disable
swaymsg output DSI-1 enable

swaymsg output HDMI-A-1 disable
swaymsg output DSI-1 enable
swaymsg output HDMI-A-1 disable
swaymsg output DSI-1 enable

(These turn off the external display, but otherwise fail silently)

wlr-randr --output DSI-1 --on --output HDMI-A-1 --off

(That gets me failed to apply configuration).

I messed with kanshi a little as well, which fails in a couple of different ways, but I figure it’s all the same root cause?
