SOLVED:
Because I replaced my Mac Mini 2028 by an MacBook Air I could now use the Mac Mini as new Smart Home Center positioned in my server rack.
It is now running Proxmox with several VMs and LXCs including HomeAssisitant.
I was running a NanoPi r67s on a iiyama 22" touchscreen to show status of my home and Music Assistant to select my music. It worked fine but I missed a bit snappiness.
So I had the idea to also use the Mac Mini to show my dashboard, because it is way faster than any of the smal systems like raspi or nanopi or similar.
I have now a VM on proxmox running debian 13 and KDE via Wayland and on top oft that TouchKio.
I made the gpu of the Mac Mini available to this VM via passthrough and transfered HDMI and USB to my touchscreen via a KVM over IP (ezcoo ROFAVEZCO). The transmitter is powerd in the severrack while the receiver gets its power through the network cable.
This setup runs fine so far and even the on screen keyboard pops up automatically. The new gained performance makes it very fun to use.
I found this project and built one for my desk with a RPI4 and its working perfect minus one issue. When I "turn off the display" via the HA switch the screen starts to flash red, green, and blue till its turned back on. I assume this is a screen saving feature of the display but how could I just have it turn off or go to a "blank screensaver" till its back on?
Thanks!
The screen flashing seems weird, but there are some known issues with HDMI screens. Please read FAQ section about Turning HDMI screen off via MQTT causes it to turn back on and create an Issue on GitHub with logs if you can't solve it.
Could you please develop this part further?
I don't seem to find how to make the touch screen sleep/wake correctly with Wayland.
I have created the autorun file in ~/config/labwc/ and it goes into sleep, but it does not want to wake up on touch (no mouse nor keyboard connected).
File is based on this example:
