Re: [X2Go-User] nxagentReconnectFailedFonts: does anyone have a solution?
Hi Uli,
I can't easily reproduce the problem since I have to travel to a different
location to use the computer that triggered the problem, so I haven't been able
to try your fix.
I will upgrade to 3.5.99.26.

Re: [X2Go-User] nxagentReconnectFailedFonts: does anyone have a solution?
As you can see the reconnect goes on after the fonts stuff. So have
you tried my suggested fix?
Please ignore the kde stuff, that is irrelevant and caused by some
default setting in x2go.
Please try upgrading to 3.5.99.26, there are more than 380 patches
included since 3.5.99.23...

Hi Uli,
Thanks for your quick response.
The nxagent version on the server is 3.5.99.23. The server is an ancient Ubuntu
14.04LTS system. I do have /usr/bin/nxdialog.
Here is my full session.log with the failed font problem:

Re: [X2Go-User] nxagentReconnectFailedFonts: does anyone have a solution?
On more thing: You can also install the nxdialog package and point the
NX_CLIENT variable to /usr/bin/nxdialog. This way you will even see
the dialogs! This is how it was intended from the beginning and it is
the correct way but unfortunately nobody has fixed that in x2go yet -
for years.

Re: [X2Go-User] nxagentReconnectFailedFonts: does anyone have a solution?
Honestly I have never seen this. Interestingly when those messages
appear it means that the system will NOT stop the reconnect but go
on:
if (!nxagentReconnectAllFonts(reconnectLossyLevel[FONT_STEP]))
{
if (!nxagentReconnectFailedFonts(reconnectLossyLevel[FONT_STEP]))
{
failedStep = FONT_STEP;
goto nxagentReconnectError;
}
else
{
#ifdef WARNING
fprintf(stderr, "nxagentReconnectSession: WARNING! Unable to
retrieve all the fonts currently in use. "
"Missing fonts have been replaced.\n");
#endif
nxagentLaunchDialog(DIALOG_FONT_REPLACEMENT);
}
}
What version of the nxagent package do you have on the server? And
what distribution do you have on the server? Please post the lines
before and after the messages you posted (from
/tmp/.x2go-/C/session.log)
Update: after thinking for some time you probably suffer from a bug
that is old indeed: dialogs are displayed using the binary that is
referred to by the NX_CLIENT variable. This variable is set wrong
inside x2go and will call a binary that suspends the session. So to
fix this
do the following on the server (as I don't know what distribution you
are using I do not know where the x2gosuspendagent binary resides, so
please adapt the path accordingly):
1. mv /usr/bin/x2gosuspendagent /usr/bin/x2gosuspendagent.orig
2. ln -s /usr/bin/true /usr/bin/x2gosuspendagent
Unfortunately you will have to fix it again after an update of the x2go stuff.
Alternatively you can change the line in x2gosuspendagent that sets
the NX_CLIENT variable. But this will only affect future sessions
while above change will also work for running sessions. You will have
to fix this after an update again, too.
Hope that helps,
Uli
