I have an IoT project that uses an SPI LCD (480x320), showing 1 full screen application on top of X11, which starts automatically, almost in kiosk mode.

 

Is it worth a lot trying to switch to Wayland? I have 2 roadblocks, which I am trying to drill through:

* tkinter app re-write in pyqt

* starting from a minimal armbian image, and install the bare minimum to have wayland and start the app

 

Solid advantage:

* Future proofing the product

 

I have these preconceived advantages:

* less resources needed: my application is fine with an OrangePi Zero 3 with 1 GB RAM, I don't want to upgrade RAM

* faster startup (now I need to wait 1 minute from power-on to app ready to use, reducing it to 30 seconds would be nice)

 

I know that I can't expect these advantages, since I use SPI instead of HDMI or DSI:

* 30 FPS

* No frame tearing

 

But really, my main objective is faster startup: will Wayland help me with that? (without having disadvantageous side effects)

I suggest you simply try. What is holding you back?
