To make ubuntu installer shows up in intel graphics: add "nomodeset" to parameters (F6).
To make ubuntu shows up after install, add "nomodeset" in /boot/grub/grub.conf like this:
linux /boot/vmlinuz-2.6.31-14-generic nomodeset root=UUID=f2fbc756-0f16-434b-90b1-9a740040b6e3 ro quiet splash
To make ubuntu identify the correct graphic card, edit /etc/X11/xorg.conf like this:
Driver "intel"


I'm installing ubuntu 9.10 desktop amd64.
The new version of ubuntu installer did not recognized my graphics card, which is Intel GMA 4500MHD. The CD booter shows up, but I could not pass to test the disk, or to test ubuntu with no install nither installer was not showing up (but it was loading).
What happen is that a strange thing splashes in the screen, and then all gets black, and still black. EVEN WITH SAFE GRAPHICS MODE.
I got EXACTLY the same problem installing FEDORA 11 x86_64 (anaconda) (didn't tryed other versions). So I will explain how I did in fedora, and how I did in ubuntu.

To workaround this problem in Fedora there are two alternatives:
The first one is to use the safe graphics mode. By this way, the installers shows up with the basic driver and the video all unconfigured. The instaled OS gets in the same way, but to correct it is easy, just change the file /etc/X11/xorg.conf in the driver line from "vesa" to "intel". Restart the xorg and all working.
The secod option is to add the following to the installer parameters: "nomodeset --xdriver=intel". This options forces anaconda to use the intel at xorg. The OS installed cames all configured, with no need to correct the problem in xorg.conf, like using safre graphics mode.

IN UBUNTU you can do this also, since I was without a computer I added the parameters "nomodeset xdriver=intel" (without the --), becouse of this I can tell right now if it will work, but adding nomodeset make it work the installer, now it shows up... BUT when the OS is installed, IT ALSO DID NOT SHOWS UP, we need to boot in live cd (with "nomodeset") and edit the /boot/grub.cfg in the line that says "linux ...", adding the nomodeset there... Also go change in the file /etc/X11/xorg.conf from "vesa" to "intel", if you dont do it, you will need to do it later to make ubuntu use the correct driver for the video card.
