Booting ubuntu with no monitor

[stroyeror]

Ok i have managed to get ubuntu to boot with no monitor but its at a low resolution. I access the computer by remote desktop connection. The current resolution is at 800 X 600. below is the current xorg.conf file what do i need to do to make the resolution higher. basically i edited the xorg.conf file in the device section of the xorg.conf file and change or added Driver "vesa"

Thanks

You are using vesa drivers. You need intel ones.
Run this command in terminal and see if it fixes your resolution:

sudo apt-get update && sudo apt-get install xserver-xorg-video-intel

Just reboot after this.

Can you run below command and follow the steps:

sudo dpkg-reconfigure -phigh xserver-xorg

[stroyeror]

Can you run below command and follow the steps:

sudo dpkg-reconfigure -phigh xserver-xorg

When i ran that i got this

fileserver@Fileserver-01:~$ sudo dpkg-reconfigure -phigh xserver-xorg
xserver-xorg postinst warning: overwriting possibly-customised configuration
   file; backup in /etc/X11/xorg.conf.20091114140258

OK after that i rebooted and it it still stopped every thing. And when i plugged a monitor into the machine it had the Ubuntu booted into low graphics mode message.

[stroyeror]

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
