[X2Go-User] Failure negotiating the session in stage '7'. Wrong version or invalid session authentication cookie.

Mon Jul 29 08:42:23 CEST 2013

Hi Roland,

sorry to let you down on this, I'm still busy doing other stuff all the
time.

The error you're getting seems to be related to your X-Server installation.
The KDE part of the agent starting is completely normal, it's just about
setting your
color depth AFAIK.

Sorry about messing arround with Master and Shadow stuff... What I ment was
this: When you're starting a GNOME session. You can just close the window
when
you're leaving the desktop. Then just start the GNOME session again once
you want
to come back. And you'll see the old one is still running and resumable.

There is another way to connect to an opened session, via the
desktopsharing feature
of x2go. But that seems unrelated...

It seems that you've messed up a part of your X or X configuration. This is
acutally
what stops your x2go client from really doing something:

check command message

X Error: BadWindow (invalid Window parameter) 3
  Major opcode: 20 (X_GetProperty)
  Resource id:  0x4004bbc
X Error: BadWindow (invalid Window parameter) 3
  Major opcode: 15 (X_QueryTree)
  Resource id:  0x4004bbc

Try to find the problem related to this. It seems that your problem is not
about
x2go...

Greetings,
Kjellski
