[X2Go-Dev] Bug#511: Cannot resume session, automatically suspends after connecting

[Mario Becroft]

I encountered the same problem, characterised by:

1. Warning about fonts in the log.

2. Session resumes briefly but then automatically suspends after about 1
second.

3. Log messages in ~/x2go/*/session.log as follows:

---
nxagentReconnectFailedFonts: WARNING! Font server tunneling not retrieved.
nxagentReconnect: WARNING! Unable to retrieve all the fonts currently in use. Mi
ssing fonts have been replaced.
nxagentSighupHandler: WARNING! Ignoring the signal in state [SESSION_GOING_UP].

The cause of the problem was indeed that some fonts were missing on the
client (a gentoo system). I simply installed all the font packages I
could find one at a time until the problem went away.

In my opinion, the x2go client is not capable of running with missing
fonts, despite the message indicating that missing fonts will be
replaced. I think this may be a bug.

Tested with x2goserver version 4.0.1.15 and x2goclient version 4.0.2.0.
