Description Jonathan Loh 2008-06-09 00:04:24 UTC

Description of problem:

Trying to run vnc and gdm it worked on FC6-7.  But I upgraded to 9, and it does
not work.  I suspect it may be due to the fact that gdm was upgraded.

What I mean by it does'nt work is that vnc connects and a window is brought up
on the remote computer but rather than having me log in.  It just gives me a
blank screen.  Previously, I was presented with a login screen.


Version-Release number of selected component (if applicable):

vnc-4.1.2-30.fc9.i386
gdm-2.22.0-5.fc9.i386

How reproducible:

Just did a fresh install on another box and it doesn't work either.
I'll include my pertinent config files


Steps to Reproduce:
1.  Need gdm, xinet, and vnc installed
2.  Add the configs
3.  vncviewer localhost:0

Oh and then you'll need to punch the requisite holes in your firewall.
I'm not using SELinux so it isn't that.

  
Actual results:

get a grey window.

Expected results:

Should be prompted for a login.

I'm having the same problem with a configuration that worked with F8.  When Xvnc
starts from xinetd on F8 two new processes start:

/usr/sbin/gdm-binary -nodaemon
/usr/libexec/gdmlogin

On F9, no extra gdm related processes start (hence the blank screen).

Comment 3 Ian Mortimer 2008-06-10 04:09:06 UTC

Similar result with vnc-ltsp-config.

It seems that you are running machine in runlevel 3. I think that in F8 you
modified /etc/inittab to start gdm also in runlevel 3 (line
"x:5:respawn:/etc/X11/prefdm -nodaemon" changed to "x:35:respawn:/etc/X11/prefdm
-nodaemon" or something similar). Would it be possible confirm it, please? Thanks

Next problem is in gdm because it parses custom.conf configuration file wrongly
- see bug #452528

In this case (on F8) the (server) host is in runlevel 5:

# runlevel
N 5

Small misunderstood. I'm talking about that broken F9 machine. Does it also
running in runlevel 5? If yes then gdm-binary should run. In other runlevels gdm
doesn't run.

Both hosts (working f8 and failing f9) are in runlevel 5 and gdm-binary is
running on both.  I was talking about an *additional* gdm-binary and a gdmlogin
process which gets launched on f8 when you make a vnc connection.  No
*additional* gdm related processes get launched on f9 when you make a vnc
connection.

What this indicates (I think) is that it's a gdm problem rather than a xinetd or
vncserver problem.
