I have a Thermalright Frozen Vision liquid cooler with display for my CPU. On windows it works perfectly with all sensors details due to a dedicated app released from the manufacturer. Unfortunately the company seems to not consider to release the same app for ubuntu, so using this OS the AIO screen remains powered off without chance to activate it via software.
The device works with a usb cable header-to-c, and by removing and re-plug manually the usb-c from the AIO, the screen magically starts, showing the wallpaper previously set on windows without sensors data, but only for 10 seconds after which it will shutdown again.
Recording events with udevadm that's what happen removing/re-plug the usb-c:
$ udevadm monitor --udev
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing

The strange thing is that no event are recorded when the screen shuts down. In fact the event list stops with a bind line.
Here the usb1/1-11 details:
$ lsusb -v -t | grep -A1 '11:'
|__ Port 11: Dev 11, If 0, Class=Vendor Specific Class, Driver=, 480M
ID 0e8d:201c MediaTek Inc.
My goal is to power on the screen only to show the wallpaper. I'm not interested about sensors measurations because simply I hate the black square. That's all.
How I can do this? Why the screen shuts down by itself?
