My USB AVR V2 has just arrived and I am trying to get it working. I have installed the utilities but…
Running as a user, I get this message:
me@wsta1:~> /usr/local/bin/pavr2gui Invalid MIT-MAGIC-COOKIE-1 keyqt.qpa.screen: QXcbConnection: Could not connect to display :0 Could not connect to any X display.
… and as Root, I get:
# pavr2gui QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root' qt.qpa.screen: QXcbConnection: Could not connect to display Could not connect to any X display.
I guess it is a problem with my local setup, but I am hoping that someone here can tell me how to correct?
I am running openSuSE Leap 15 64bit, with the KDE plasma desktop.
