Comment # 4 on bug 1031501 from Simon Fels

After some more research the real problem comes down to XAUTHORITY being set to
/tmp/xauth-1000-_0 which can't be passed into the snap environment as each snap
gets its private /tmp. The environment variable is correctly set in the snap
environment but no application can access the referenced xauth file as it is
not available.


This needs a change in snap-confine to correctly pass the current xauth file
into the snap environment. Filed an upstream bug for this at
