Why is it trying to create that in there ??
Normal users shouldn't have write access there . . .

This error message comes from

        libXcomp.so.x.y.z

Which on my machine (OpenSuSE)lives in 

        /usr/lib/NX/lib/

so it could be defaulting to it's own directory as a last resort
if yours is in /usr/NX etc etc

So

It might be an issue with the 3.5.0 libraries writing there
as a last resort, or the nomachine coders may have changed
something here in tis version.

Hmmm

If it can't create the session file directory, then where did you get
the session file from ???

As far as the server is concerned,
        you should have a session file in:-

/var/lib/nxserver/db/running/sessionId{ABCDEF1234567890ABCDEF1234567890}
created by user nx (unless ubuntu put it elsewhere)

        and :-
a session directory below your home directory eg.

/home/myuserid/.nx/C-server-1001-ABCDEF1234567890ABCDEF1234567890/


If you log on to the server and try the following:-

        sudo su -l -s /bin/bash -c "echo \$HOME" nx

        sudo egrep -i "(NOMACHINE_(SERVER|NX_HOME_DIR)|USER_FAKE_HOME)=" 
/etc/nxserver/node.conf /usr/bin/nxloadconfig
        ^ All on one line

        sudo find /var/lib/nxserver/ -type d -ls

        grep ":" /etc/passwd|cut -d":" -f6


. . . then the results will tell us what FreeNX thinks
it's doing as a first start.

Which versions of FreeNX are installed ??

Did you move up to 3.5.0, if so did it work before ??
