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.
