Hello,
I'm trying to compile and RPM-package the X2GO Client, Server and the NX-Libs and I'm having a problem with the X2Go Server. I tried the following:
- install the NX-Libs from the source
- install the X2Go Server from the source
- tried to create a X2GO database with 'x2godbadmin --createdb' (how can I really check if the database was successfully created?)
- started the X2Go server with the init-script (I see a process "/usr/bin/perl /usr/sbin/x2gocleansessions" running)
- I try to connect with the X2Go client to the server and I get the following output on the client's console:
Fontconfig warning: no <cachedir> elements found. Check configuration. Fontconfig warning: adding <cachedir>/var/cache/fontconfig</cachedir> Fontconfig warning: adding <cachedir>~/.fontconfig</cachedir> ONMainWindow constructor

Any ideas where the problem could be? Where does the X2GO Server log it's messages?

Hello,
Do you have x2goagent installed or at least a wrapper script arround nxagent named x2goagent? I had the same on Mageia, when building x2goserver.
I will most likely finish the package tommorow and submit it to the distribution build service. I can give you a linkt to my spec as soon as it is in svn, you can compare it to yours then.

Hi Oliver,
thanks for your reply! No, I had no idea I need a x2goagent wrapper. I found one in the nx-libs-source/bin/ directory, but it doesn't make any sense, because it calls another x2goagent:
NX_LIBS=/usr/lib/nx exec $NX_LIBS/../x2go/x2goagent "$@"
How did you solve the problem?
Thanks, Bogdan

How did you solve the problem? You'll find my spec here: http://svnweb.mageia.org/packages/cauldron/x2goserver/current/SPECS/x2goserv...
But it's not quite ready yet. First of all I should build the real x2goagent (to be found here: http://code.x2go.org/releases/source/x2goagent/), but I didn't get it to build till now. But Mike told me, I would be without upstream support if I used nxagent instead of x2goagent. And second I'm just writing a systemd service file for it (something I never did before).
But those things said, my package does work :)

Just for the record, x2goagent is now provided in nx-libs.git, tarballs at http://code.x2go.org/releases/source/nx-libs

Create a link to nxagent:
ln -s /usr/lib/nx/nxagent /usr/lib/x2go/x2goagent
I assume it is because of backward compatibility. The nxagent from nx-libs (NX redistributed) is patched so that it knows when it is run as "x2goagent" and when as "nxagent".
You can also have a look at the debian package to see what is installed and where:
http://packages.x2go.org/debian/pool/main/n/nx-libs/x2goagent_3.5.0.10-0+whe...
Do not use x2goagent version older then 3.5.0.10, since these were a separate binary, not just a wrapper to NX redistributed nxagent.

Hi,
I'm trying to connect to a self-compilted and rpm-packaged X2GO Server (the self-compiled/packaged NX LIbs are installed). I also liked x2goagent to nxagent:
[root@rhel6-64 x86_64]# ls -al /usr/lib/x2go/x2goagent lrwxrwxrwx. 1 root root 16 Feb 4 04:01 /usr/lib/x2go/x2goagent -> /usr/bin/nxagent
But the connection still doesn't work. This is what the X2Go Server logs (debug mode):

Install the nxagent binary and the NX-X11 libraries to
/usr/lib/nx/
Create a symlink for x2goagent, pointing to nxagent (the binary, not
the wrapper):
/usr/lib/x2go/x2goagent -> /usr/lib/nx/nxagent
For x2goagent place a wrapper script that tweaks LD_LIBRARY_PATH into
/usr/bin/x2goagent, the following link shows a patch from our patchset

Also just for the record...
The above assumption is not as precise as it could be. The merge of
nxagent and x2goagent has only one reason. That is getting rid of 20mb
of forked code. The 20mb fork (formerly known as x2goagent.git on X2Go
Git, http://git.x2go.org) has now been reduced to 7-8 patch files
against NoMachine's original NX sources.
