I changed the title of this thread. I believe this error message is the cause of the problem, but I don't know how to fix.
Right now, among the dozen Ubuntu 14.04 servers I run, half of them x2go works, and other half do not work.
all machines have applied the latest updates (x2go 4.1.0-1517 for the server components, 4.1.1.1-1719 for the client, and libnx-x11-6: 2:3.5.99.16-0)
I compared the package versions, I can't see any difference between the servers that x2go works vs those failed - all x2go/nx components have identical versions.
when connecting to the machine have problems, the server side log gives "|Unable to open display 'nx/nx|", full log see below.
this issue only happens in March after some x2go package updates.
please help!

hi Mihai and other x2go users,
I am wondering if you have any further comments or suggestions, I am still unable to connect to more than half of my servers. All failed in the same messages:
*On the client side:*
|Connection failed.||Failed to start X2Go Agent session with ID fangq-...._stDXFCE_dp24. X2Go Agent terminated unexpectedly. Aborting session startup. |
*on the server side:*

all updated with the latest version of Ubuntu 14.04

Looks good, all old packages are in rc state (i.e., uninstalled, but not purged). Sorry, that should have been ls -ldh /usr/lib/*86*/nx/X11/*
I'm interested in the files in there.
here you go | ||*fangq@zodiac:~$ ls -ldh /usr/lib/*86*/nx/X11/**|| ||lrwxrwxrwx 1 root root 20 Mar 17 08:41 /usr/lib/x86_64-linux-gnu/nx/X11/libX11.so.6 -> ../../libNX_X11.so.6|| ||lrwxrwxrwx 1 root root 24 Mar 17 08:41 /usr/lib/x86_64-linux-gnu/nx/X11/libX11.so.6.3.0 -> ../../libNX_X11.so.6.3.0|
Like the other user on the mailing list wrote, purging sessions can be done using rm -vf /var/lib/x2go/x2go_sessions; x2godbadmin --createdb (both as root), but if there are no sessions currently that won't do anything useful.
I see. are there other logs that I can find/provide to narrow down the issue?
thank you again for your help.
