I'm not sure if I set this up properly. I want to start Eclipse CDT on my Ubuntu 8.04 install using X11 through VNC.

When I try to run eclipse through vnc viewer command line using ./eclipse it hangs for a few seconds then fails. No error message is output on the command line.

Is there a startup error log or some place I can look to find out what's happening? Or am I doing this wrong?

    So, you are using a remote client running VNC to connect to your Ubuntu 8.04 system, and are trying to run Eclipse w/ CDT on Ubuntu? One assumes other desktop stuff works ok? Read More

    So, are you connecting to the desktop, or a frame buffer X-server? Also, what is your client? Windows? Linux? And what is the Linux distribution+version+kernel and X-Server you are running on the host? And what VNC version are you running on host and client? Read More

Yeah like I can run firefox from the command line through the vnc viewer and some stripped down version of it starts up, like without a minimize button, but it still works. I haven't tried any other apps except eclipse/firefox.

Connecting to a frame buffer x server as described here, "For Unix, the traditional VNC implementation includes a "virtual" X11 server Xvnc"... http://www.karlrunge.com/x11vnc/

Although I am actually connecting to Ubuntu desktop so I might be able to connect to the real thing. I would rather get this working though.

client: vnc viewer 4.1 for windows 7 64-bit ultimate
server: ubuntu desktop 8.04 lts
kernel: 2.6.24-22-generic
vnc: vnc4server, 4.1.1+xorg1.0.2-0ubuntu7

X-server: I did X -version result was,
X.Org X Server 1.4.0.90,
Release Date: 5 September 2007
X Protocol Version 11, Revision 0
Build Operating System: Linux Ubuntu (xorg-server 2:1.4.1~git20080131-1ubuntu9.2)

I found the vnc log file which shows what happens after I connect, start firefox successfully, start eclipse unsuccessfully and disconnect.

I tried to find the log file for X11, /var/log/Xorg but there was no file like it.
I searched through xorg.conf but couldn't find an option to enable logging.
I think if I could enable logging for X it would help.

These lines are probably what is relevant:

Could not init font path element /usr/share/fonts/X11/TTF/, removing from list!
Could not init font path element /usr/share/fonts/X11/OTF, removing from list!
Could not init font path element /usr/share/fonts/X11/CID/, removing from list!

Check if these directories exist, and have appropriate permissions set.

Ok I've verified that the problem is eclipse.

Is there some kind of version clash here?

desktop: ubuntu desktop 8.04 lts
kernel: 2.6.24-22-generic
CDT 7.0.2 for Eclipse Helios
jre1.6.0_24

When I do ./eclipse it just hangs for a few seconds and I get no error at all. I also don't know if there is a log file that would store startup errors. Is anyone familiar with this kind of problem?

My eclipse.ini is the default file with the -vm argument added,

-startup
plugins/org.eclipse.equinox.launcher_1.1.1.R36x_v20101122_1400.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.gtk.linux.x86_1.1.2.R36x_v20101019_1345
-product
org.eclipse.epp.package.cpp.product
--launcher.defaultAction
openFile
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize

I booted into my ubuntu 10 partition on my windows machine, did the exact same thing installing eclipse 3.6 helios with jre 1.6 and eclipse ran fine.

Right now I need to know how to get a description of the error that is occurring even though it is not output to the command line or ubuntu's system log /var/log/messages.

./eclipse just hangs and then returns to the command line

Ok I'm formatting my server to ubuntu 10 desktop.

I tried upgrading some packages to be able to install eclipse, after doing a sudo apt-get install eclipse, and am just running into too many package upgrade problems.

Some of them don't smoothly upgrade

Thats fine, I would rather format to ubuntu 10 in this case than troubleshoot package upgrade errors.

shwick- you programmed it from the ubunto tunnel.
Do you know if and how can I do it without using the tunnel? (remoting vnc through eclipse on ubunto)
