I did a reinstall of Jaunty this weekend.
All is working well. The previous install I had was Kubuntu 7.10.
I run this box as a headless server and connect to it vis VNC tunneled through ssh.
In the Kubuntu install, I had no monitor connected. I had no issues connecting via VNC to this machine. I could reboot with no monitor attached and when I connected via VNC i had my KDE desktop.
Now that I am using Ubuntu 9.04, If a monitor is connected at boot-time I can connect via VNC. I can remove the monitor and it can still connect via VNC. If I reboot with the monitor disconnected. I can connect via SSH but VNC will not connect. If I plug the monitor back in I see the following error dialog:

Ubuntu is running in low graphics mode.
The following errors were encountered:
(EE) intel(0): No valid Modes
(EE) Screens found but none have a usable configuration.
The other interesting thing is that this box also runs a squid proxy. Squid appears to be running, but not functioning.

If I reboot with the monitor connected, all is well again.
I do not want to have a monitor connected to this box when it will not be used 99.9% of the time.

Here is my /etc/X11/xorg.conf

# xorg.conf (X.Org X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the xorg.conf manual page.
# (Type "man xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
#
# Note that some configuration settings that could be done previously
# in this file, now are automatically configured by the server and settings
# here are ignored.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following command:
# sudo dpkg-reconfigure -phigh xserver-xorg

The monitor I used when it is attached is a Dell E153FTPc.

Any thoughts?

Exactly the same problem here. How do I VNC into a monitor-less Ubuntu 9.04 system?

There is some info here (see below), but I have still yet to solve this. Anytime I need to reboot I have to connect a monitor. Total pain.
