Problem with KlipperScreen

[zdzihu]

Hi, I followed the tutorial and installed everything without any errors. However after final phone restart the KlipperScreen isn't working. XSDL starts and shows error: "Error: X server failed to initialize. Try to use different display.".

I have tested this with 1 smartphone Android 6.0.1 and Tablet Android 7.1.1, with both Debian "Oldstable" and Ubuntu Focal - same problem. Thank you in advance for help.
