Ubuntu won't boot without monitor plugged in

Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Device"
SubSection "Display"
Depth 24
Modes "1280x800" "1024x768"
EndSubSection
EndSection

PS I don't think that the vesa driver supports that resolution

Adding that to the screen section did not work..

any other ideas?

OK i have figured it out

In the Device section you have to add

Driver "vesa"

In the monitor section you have to add

HorizSync       28-73

Then reboot.

Thats what worked for me.

Below is my 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

Hi to all,

the title of the discussion says it all, i have the same problem BUT with ubuntu 9.10 therefore there is no xorg.conf or gmd.conf. What can i do to have a headless unit?

I tried to create a xorg.conf "default" file, but all i had at reboot was a weird (because montior kept on flashing) logging in screen (which i didnt have before as i set it to automatic login) and the impossibility to type to actually login! .... I formatted and installed again 9.10.

i've already posted a similar argument in the italian forum , but with no success: nobody seems to know anything about it!

Those who wonder why i re-installed 9.10 rather than 9.04 here is the answer: i did the awful mistake of using ext4. So if i want to use my /home without formating it and lose all my data i have to keep on using 9.10.

Please, help me! There is no sense in having a little server with a huge monitor plugged in!

Thanks,

Andrea

Hi, what version of ubuntu do you have? because i would try to use your xorg.conf.

I'm currently using 9.10

i solved it, using the first xorg.conf details... Problem is i cant get more than 800x600....

Obviusly i set the xorg file under modes at "1024x768" but it doesent work!

this worked for me. You have do disable KMS (KernelModeSetting) . Here you can see how to turn it off for Intel, Ati,Nvidia: https://wiki.ubuntu.com/X/KernelModeSetting


I had to type for my intel graphics chip :
sudo su
echo options i915 modeset=0 > /etc/modprobe.d/i915-kms.conf


reboot and done.

I just finished configuring my headless home server (AKA: old PC i wanted to give some use).

I followed this post: HERE

Works like a charm now.

Hope it helps you guys.
