[X2Go-User] Best client/server pairings for RHEL 6 server and linux/windows clients?

[John Stoffel]

Guys,

I'm using x2go server on a CentOS 6.9 box, kept quite upto date, and I
have no problems connecting to it from both the desktop of that
system, and from home when I'm connecting in from a Linux desktop.  My
versions are:

Server (Linux CentOS 6.9):

  x2goclient-4.0.1.4-1.el6.x86_64
  x2goserver-4.0.1.20-1.el6.x86_64
  x2golxdebindings-debuginfo-1.0.2.4-1.1.x86_64
  x2goserver-xsession-4.0.1.20-1.el6.x86_64
  python-x2go-0.5.0.3-1.el6.noarch
  x2goagent-3.5.0.32-3.1.x86_64


Linux Client (Linux Mint 18.3):
  ii  nxproxy 2:3.5.0.33-0x2go1+git20180204.776+8.main.1   amd64        NX proxy
  ii  x2go-keyring 2012.07.23~jessie~main~17~build1             all          GnuPG keys
     of all X2Go developers and the X2Go archive
  ii  x2goclient  4.1.1.1-0x2go1+git20180302.1732+8.main.1     amd64        X2Go Client
     application (Qt4)


But when I try to use the latest client stuff from my Windows 7
system, I just get a connection which shows up for a second, then
disconnects and returns me to the connection screen.  I can't figure
out what I'm doing wrong.  But I'm loathe to upgrade my server just in
case I break a working setup.

In the meantime I've built a new CentOS-7.4 system, which is using the
same packages as my CentOS 6.9 server, but for some reason I just
can't reliably connect there either.

Been following the mailing list for a while, since this is really my
best option to be able to have my linux sessions travel around with
me.  But debugging has been a chore, since there are so many files and
places which need to be looked into.  And it's not clear WHY
connections fail.

And actually, does RHEL/CentOS 7 with a Gnome desktop even work?  Is
there an issue with OpenGL like there is with VNC desktops?

Thanks,
John
