Re: [X2Go-User] Unable to start firefox docker inside x2go
No it only works on the console (through spice/vnc in this case, but display is :0 ) and I need to do a 'xhost +' first (not needed on my laptop strangely) With the x2go remote display it simply don't work (not via unix socket, or tcp or hard coded $DISPLAY with the IP of the docker host) On 16-04-18 16:05, Ulrich Sibiller wrote: Hmm, if it works with xhost+ this looks like a cookie issue.
