Re: [Xen-users] cant get X on domainU
1. ssh -X domainU
steps: on domain U
$ export DISPLAY=:0
$ xhost +
xhost: unable to open display ":0"
on domain0 ssh -X domainU
result: ssh conection established no X forwarding starts.
after login tried startx, but get message user not authorized to start x
You shouldn't really need to do all that... If X forwarding is enabled in
the sshd config in the domU, it will do all the setup required
automatically when you ssh -X in. startx won't work in any case because
it'll try and start an X server, but just running random X programs ought
to work.
2. vnc
installed vncserver on domainU,
$ vncserver
New 'X' desktop is playbox-breezy-01-U:1
Starting applications specified in /etc/X11/Xsession
Log file is /home/slava/.vnc/playbox-breezy-01-U:1.log
$ cat .vnc/playbox-breezy-01-U\:1.log

27/12/05 19:22:49 Desktop name 'X' (playbox-breezy-01-U:1)
27/12/05 19:22:49 Protocol version supported 3.3
27/12/05 19:22:49 Listening for VNC connections on TCP port 5901
on domain 0 tried to connect with gnome terminal server client using vnc
but connection gets refused
Sounds weird... Can you try telnetting from dom0 to port 5901 in the domU
to see if the connection is open an accessible? What error does the Gnome
client give? Have you tried just using plain vncviewer?
3 freenx
install freenx on domainU, nxclient on domain0, added user, setup
password. when try to connect i cant get past authentication completed

Ick, that doesn't look nice. Whose version of FreeNX were you using?
Personally I like NX but I've generally not found it straightforward to set
up.
Cheers,
Mark
