Running in raspberry pi using bookworm desktop

[ashah7]

I'm trying to get cage using by starting a kiosk browser on boot
I'm just in the first instance trying to get it working
When I run the command

cage -- chromium --kiosk

I'm getting the error
00:00:00.000 [../cage.c:328] Unable to create the wlroots allocator

I've tried using
DISPLAY=wayland
WLR_BACKENDS=headless
WLR_BACKENDS=wayland1
WLR_BACKENDS=xwayland0
WLR_BACKENDS=xwayland1

but nothing works

I have two screen connected
I'm using the latest bookworm (Nov 2024) desktop build (and tried the lite build as well)
This version is using labwc, not sure if that makes a difference. On the labwc github they recommended cage for kiosk setups that how I found this

If Labwc is running, there is great change for Cage to be able to run.
Are you trying to run Cage as the primary Wayland compositor or as a nested one in Labwc?
Where your Cage binary comes from? Official Debian APT repositories or you compile it youself?

I installed from the repo
sudo apt-get install cage

Not sure about the nested question, whatever bookworm desktop uses I suppose (sorry!)

Just tried using it from sway after installing it on bookworm lite

sudo apt-get -y install sway cage xwayland-protocols

After launching into the sway desktop I run

cage chromium

And I get the same error
Unable to create the wlroots allocator
