HOWTO: Install FreeNX

[melchior]

freenx is great, 10 times faster than vnc out of ubuntu!

but, i need to have the same behaviour as vnc. i.e. when I start a vnc session it displays it as display :1 and continues to display on display :0

so, for what i want, i have display :0 as my tv. and display :1 as the remote window. mirrored.

there are apparently ways to do this with kde, but how with gnome?

Please help!

Except FreeNX can use VNC and generally does it much faster. If you're
using krfb or X11vnc (I don't know if there's a similar tool for Gnome),
you can use FreeNX to connect to the session exactly as VNC would.

edit: Ok, well I figured out I can run xvncviewer from within the freenx session... which is a good start, but it would be better if i could just use freenx...

oh, and i get major image encoding problems unless i set the image to standard bitmaps... is this just me or everyone? i'm using an nvidia mx440

edit #2 : Well, I've read people talk about using freenx as a proxy to tunnel a vnc connection.... how do I do that? I am using the mac client.... Any help would be appreciated!

Anyone have any idea why?

Apparently he changed the repos but never updated the HOWTO: http://free.linux.hp.com/~brett/seve...seveas/freenx/

anyone have an update on how to make freenx work with dapper?

[Mikieboyblue]

Hello, I am new to linux and am very familar with Windows. I would like to use FreeNX as a true desktop sharing utility and now start a new x-session. I have KDE installed and both KRFB and X11VNC. How can I set these up to work with FreeNX Server? The FreeNX portion works fine.

Thanks!!

[acegolfer]

I really like FreeNX. Much better than VNC when working. But there's one critical problem that I'm facing.

My UBUNTU machine is at my office running 24/7 and I access it via FreeNX from my home WIN XP. My DSL connection using a router is usually stable. But sometimes it drops and my FreeNX session terminates before I have a chance to save my session.

When I tried to reconnect using FreeNX, I get a new session instead of the resumed one. I can locate the applications running from the existing sessions but how do I restore it?

This is a major problem for those who work on documents. Any clues?

[Infernal]

i have 2 problems

1) i've downloaded the freenx client, but i can't connect to my server, i get this error:

NX> 203 NXSSH running with pid: 3012
NX> 285 Enabling check on switch command
NX> 285 Enabling skip of SSH config files
NX> 200 Connected to address: 10.0.0.40 on port: 22
NX> 202 Authenticating user: nx
NX> 208 Using auth method: publickey
NX> 204 Authentication failed.

i'm using root to login

2) is it possible to connect to server using the Remote Desktop Connection that's standard in win XP?

[vyktor69]

Ok, I have a silly question but I have to ask it. I got freenx setup and I'm able to connect to it from my windows xp box at work. (Had a time figuring out I had to enable SSL on the NX client) and I get connected. The only problem is that I use Gnome and I can't see the top of my screen using the NX client. Anybody have any ideas?
