Previously I had Ubuntu 11.04 and I could boot with no monitor attached.

Now I have installed Ubuntu 12.10 with autologin and I've found that is incapable of booting correctly if the monitor isn't attached.

Is there a way to "force" Ubuntu to "remember" last monitor attached or to define a virtual one to allow a "normal" booting?

  • @john I've tried to clarify your question for others, but let me know (or re-edit) if I've gone the wrong way. – belacqua Nov 02 '12 at 17:22

You need to do this :

go to directory :

cd /etc/X11/

cp xorg.conf xorg.bak

sudo gedit xorg.conf

Look for this section "Device" in the file, and update the file to be like this :

Section "Device"
     Identifier "Configured Device"
     Driver "vesa"
EndSection

If you dont find this section then put it at the top of the file.

Try to keep the complete file consistent.

  • Thanks Vikash, my driver is already vesa, and it isn't working. Here is my xorg.conf: Section "Device" Identifier "Configured Video Device" Driver "vesa" Option "NoDDCValue" "True" EndSection Section "Monitor" Identifier "Configured Monitor" HorizSync 31.5-48.5 VertRefresh 50-70 EndSection Section "Screen" Identifier "Default Screen" Monitor "Configured Monitor" Device "Configured Video Device" DefaultDepth 24 SubSection "Display" Depth 24 Modes "1024x768" EndSubSection EndSection – john Nov 02 '12 at 17:20
  • Try and change the < Identifier "Card0" > and see if it works... – Vikash Singh Nov 02 '12 at 18:02
  • Nope, and sorry about the raw xorg.conf I couldn't figure it how to format it properly. – john Nov 02 '12 at 18:28
  • Anyone know why this feature is broken from previous versions? Is this a bug? – john Nov 02 '12 at 19:41
