Switching between HDMI and internal display on A311D

MNT Pocket Reform
1

As it is known, noone has yet figured out how to make A311D output to the internal display and HDMI on MNT Reform / MNT Pocket Reform at the same time, and switching from one to the other is not automatic. We might integrate buttons for this in a future wayland desktop panel, but in the meantime here are two commands I use (you could also bind these to keyboard shortcuts in .config/sway/config).

To use these, you need to sudo apt install wlr-randr once.

Switching to HDMI (and a resolution of choice)

wlr-randr --output DSI-1 --off --output HDMI-A-1 --on --custom-mode "1920x1080@60Hz"

Switching back to Internal Display

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

Interesting… on MNT Reform Classic with A311D I used to have:

Switching to HDMI (and a resolution of choice)

swaymsg output eDP-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

Switching back to Internal Display

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

Especially when switching back, enabling and disabling the display twice used to be necessary. This restriction is gone with wlr-randr? That’s nice! :smiley:

I’ve just tried Kanshi on my A311D Reform and it seems to work wonderfully! I added this to my Kanshi config:

profile "Reform - Home" {
        output "Philips Consumer Electronics Company PHL 246V5 AU01438007831" enable mode 1920x1080 position 0,0
        output eDP-1 disable
}

profile "Reform Undocked" {
        output eDP-1 enable
}

…and my Reform now outputs to my HDMI monitor if it’s plugged in and switches back to the internal display automatically when I unplug it.

Uuuh kanshi is for wayland what autorandr is for xorg. I used to be a autorandr user. This is perfect! If only one display can be used at a time, why would one not automatically switch to hdmi right as it is plugged in? Thank you!

No problem! :slight_smile:

I used to use autorandr too, and the one thing I miss about it when using Kanshi is that you have to manage the config file manually; there’s no equivalent of autorandr --save. But the upside to that is that I have my Kanshi config in my dotfiles so it applies to all my machines as well.

For now I only have it configured to switch if I plug into specific monitors, but if you find a way to have it switch to any connected HDMI device when plugged in I’d be interested in seeing what that config looks like.

Unfortunately, I don’t seem to be having much success with kanshi. It works “sometimes” but after a few unplugs and replugs I start getting messages like:

failed to apply configuration for profile 'Reform Undocked'

So my internal screen stays black. Re-plugging HDMI brings at least that one back but at some point, turning on HDMI will fail as well with:

no profile matched

And then I have literally no output anymore. :frowning:
