[lug] VNC and gdm

[Bonnell, Doug]

It's the end of the work day and my brain is fried, but
I'll try to help.

First of all, if you are using the vnc that is supplied 
with the more recent versions of RedHat, then get to the
VNC website and get their version instead:

http://www.uk.research.att.com/vnc/

The RedHat version doesn't have the -inet option, which is
required for the vnc server to be used with gdm via the
xdmcp protocol.

Do a search on the BLUG archive:

http://archive.lug.boulder.co.us/

use vnc gdm bonnell to see my posts about this.

Hope this helps,

Doug

Hi all-

I've been trying to setup a VNC server to be run from gdm.  I've dug around
the net a whole bunch and everyone seems to be having the same problem: they
set it up, the vncXserver gets launched, but no gdm login screen is actually
presented -- just a blank screen as if X doesn't have a window manager.
I've added VNC to xdm, and it works just fine, but I'm trying to sell the
idea to some management and xdm is "too ugly."

Here's what I have in gdm.conf:
[servers]
1=/usr/local/bin/Xvnc :1 -depth 8 -geometry 800x600 -httpd
/usr/local/vnc/classes

Here's what I put in Xservers for xdm that works:
:2 local /usr/local/bin/Xvnc :2 -depth 8 -geometry 800x600 -httpd
/usr/local/vnc/classes

I've searched through Google, newsgroups and a whole bunch o' other
resources and it appears that no one has the answer.  Has anyone here
battled this and found one?  I've looked at the inetd option for VNC, but I
can't see any way that I would use it to provide a web accessible session?
Does anyone have any ideas on how I could use it in this manner?  The
ultimate goal is to get a clean gdm style login using a web browser -- and
the compression advantages of VNC would be nice for remote administration.

I guess if I find out that I'm SOL, I'll try to spiff up xdm a bit ... But
it's been a looong time and I'd prefer the flexibility of gdm.

As usual, thanks a million!
