unable to display when using vnc

[xelcho]

Ubuntu 18.04 kde 5.15.x pynsource 0+git.8095336 4 stable tigervnc 1.9x when connecting via vnc I am unable to load pynsource. I get this response: Running Community Edition No protocol specified Unable to access the X Display, is $DISPLAY set properly?

Is there cli I can use to set the display, that I am missing?

I’ve never tried that particular use case, a quick google suggests some possible clues/solutions:

• https://github.com/kevinhughes27/TensorKart/issues/54
• possibly setting export DISPLAY=:0 as per https://www.cnblogs.com/tibetanmastiff/p/4428714.html

Please report back if you have any success!
