This is I what I did with the HP laptop's vga port and my Old Samsung
CRT Monitor (http://reviews.cnet.com/crt-monitors/samsung-syncmaster-
591s-crt/4507-3175_7-31312643.html) following the directions on this
video as an example for me (http://www.youtube.com/watch?v=9tHruGnmGjY).
So I had a LED display and a CRT display.
1. Connected CRT VGA port to laptop VGA port. Turned on laptop and CRT display.
2. Grub Menu → Ubuntu. That is, booting Ubuntu as normal mode with this Boot
options:
linux /vmlinuz-3.8.0-16-generic root= ..... ro quiet splash --
vga=792 $vt_handoff
3. A graphical prompt login window appears on both LED and CRT displays.
4. Logged on. LED display turns off. CRT display shows Ubuntu graphical desktop.
5. On my HP laptop I pressed the F4 key to load the Display settings window
with these options:
■ Laptop
□ Samsung 14"
□ Both displays cloned
6. Selected 'Both displays cloned':
□ Laptop
□ Samsung 14"
■ Both displays cloned.
And both LED and CRT diplays show the Ubuntu desktop.
8. Executed $ dmesg > file_on_usb_drive
9. Copied /var/log/Xorg.0.log to folder_on_usb_drive.
10. Copied /etc/default/grub to folder_on_usb_drive.
11. Searched on dmesg.log file for "nomodeset" text string but no matches were
found.
That'all.

Title:
Ubuntu 13.04 Beta 2- Intel HD Graphics 3000 - No screen
Status in “xserver-xorg-video-intel” package in Ubuntu:
New
Bug description:
I've tried to install Ubuntu 13.04 Beta 2 on my HP laptop HP 1000-1220LA
Notebook
(http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&lc=en&dlc=en&docname=c03503799)
but there's a problem with the video/screen.
My HP laptop comes con Windows 8 preinstalled with UEFI and in order to
install Ubuntu 13.04 Beta 2 I deactivated the secured boot feature of the UEFI.
The screen resolution is 1366 x 768, 32 bits.
First, the graphical installer didn't show, so I modified the CD BOOT Option
Configuration Line using nomodeset and vga=792 (1024x768, 24 bits) (
http://en.wikipedia.org/wiki/VESA_BIOS_Extensions#Linux_video_mode_numbers)
(https://help.ubuntu.com/community/BootOptions#Changing_the_CD_Boot_Option_Configuration_Line)
to:
BOOT Options ..... nomodeset quiet splash --
vga=792
After, pressing F10 key the graphical install opened and I proceeded
with installation, hoping a dual system. Then, I had to fix the dual
system using refind (www.rodsbooks.com/refind). I know this dual
system is another kind of bug. I'm just telling what I did.
Then, the GRUB screen shows the options to launch Ubuntu 13.04 and Windows 8.
If I select Ubuntu, the screen becomes blank again.
I modified the boot options using nomodeset and vga=792:
linux /vmlinux-3.8.0-16-generic ..... nomodeset
quiet splash $vt_handoff -- vga=792
Which resulted in a command line system. After logging in this command
line system I executed this command to activate the graphical system:
$sudo startx
But the Org video server is unable to run and shows me this log Xorg.0.log
(Attachment).
I think it is a problem with the xserver-xorg-video-intel package.
