Hi Burnce,

thanks for your detailled feedback.

Note, that non of the upstream developers works under rhel or  
opensuse. We have to rely on people like you giving feedback. So, may  
I ask you to help us improving X2Go for RPM-based distributions.

Please sign up for our wiki and prepare such a page. I have just  
provided a skeleton.

http://wiki.x2go.org/doku.php/wiki:x2go-repository-redhat

Please point us to the relevant (outdated) pages in the wiki. Send us  
the URLs please.

The RPM repositories are not maintained by us directly (at the  
moment). I know that Alex has got involved with RPM packaging lately,  
so he might give an update here. The RPM packaging had been induced by  
Michael Kromer, the developer was Jan Engelhardt.

-> PING at MichaelKromer -> this needs fixing in the RPM repositories

This is not so on Debian. If all packages mentioned in Debian control  
files of x2goserver and x2goagent / libnx-x11 are installed (on  
Debian/Ubuntu) then it is possible to draw in a minimal GNOME setup  
(gnome-session package) and to use that with X2Go.

http://code.x2go.org/gitweb?p=x2goserver.git;a=blob;f=debian/control
http://code.x2go.org/gitweb?p=nx-libs.git;a=blob;f=debian/control

About the runlevel issue, I am not sure. Is SSH started on runlevel 3?  
I guess so. Hmmm... Once you can login via SSH, X2Go login should  
normally work as well...

An example script can be this:
http://code.x2go.org/gitweb?p=x2goserver.git;a=blob;f=debian/x2goserver.init

If that is not in the RPM x2goserver package, then this needs fixing.

Please give us a hand and help improve the RPM aspects of X2Go! Thanks!
