52pi 7" touchscreen 1024x600 for VIM1 with ubuntu?

have tried 52pi multitouch 7" screen (to be connected via HDMI and USB). Works perfectly with Win10 out of the box.

With Khadas Vim1 the image is OK, adjusts automatically. Touchscreen does not work however. dmesg shows the following:
603.953597] usb 1-1.4: new high-speed USB device number 5 using xhci-hcd

Has anyone any experience how to get that touch screen working?

I think that one is still in the “HDMI resolutions” testing, please check over there
