Error: QXcbConnection: Could not connect to display :0 #1

The wallet was working for a moment.

Wallet is running

However sometimes it does not run, I get an error as below:

$ ./solarcoin-qt.sh 
QXcbConnection: Could not connect to display :0

(Running Ubuntu 17.10 with i3 and x11)

I will see if I can debug it. Any idea?

It must be something to do with the generated xauth file. I wasn't able to reproduce it so far. I am not an expert in the xauth area, but if you can provide some additional info eg. the contents and permissions of /tmp/.docker.xauth when you get that error, I could do some research. As a workaround running something like xhost + before you start solarcoin-qt.sh might help.

Hmmm. I was not able to reproduce it. Now it works without issue (I did not change anything on my system). I will reopen and provide additional info if it occurs again.
