evdi driver + intel xorg driver tearing
 

Hello! I've got the following system configuration: qml mediaplayer on fullhd display(i915 GPU) + displaylink usb screen with UI. By default, Ubuntu 18.04 uses udl driver for usb screen + some driver for xorg, everything is ok, but there is tearing in mediaplayer. So, according most popular solution in the internet, i've created 20-intel.conf for Xorg with "TearFree" parameter. Tearing now is off, but system doesn't see usb screen. Then, i've installed evdi driver, usb screen is listed by xrand, but when i'm trying to set mode for it, it stills black. Here is output of DLSupportTool. So does anyone know, how to setup DL usb screen + teared off fullhd screen?

Thank you!
