Qt.qpa.screen: QXcbConnection: Could not connect to display

When I attempt to connect to the GO1 remotely and run “rviz ./build_map_rviz” I get the following error:

qt.qpa.screen: QXcbConnection: Could not connect to display 
Could not connect to any X display.

I’m using the docker image supplied by Droneblocks.

docker image remote lidar

Hello all:

This issue was occurring because I was attempting to launch RVIZ remotely from the Go1 instead of my local computer. All is working well. Thanks.

Hi Jeff, really sorry to not get back to you sooner. I’m just now seeing your messages, but glad you have it sorted out. Yes, running RVIZ on Go1 is not something we have been able to achieve. All or our development/testing has been done with RVIZ running on a host machine connected to Go1 over the network. Let us know how everything is coming along. I’d love to hear what you’re up to!

Thanks Dennis. I put a few post on LinkedIn. :grinning:
