    12.10 USB live boot hangs on splash screen

    I have originally posted this on ask ubuntu, but haven't got any responses. So I'm just crying here for help.

    I've been a good Ubuntu user since 11.4 on my 64bit Dell Inspiron N4010 laptop, and everytime installed with USB stick but this time, I can't install Ubuntu 12.10 on my laptop. I had this issue again but then the networking solution didn't work since 12.10, so everytime it happened I made an upgrade on my existing installation and it just worked. But now I can't fix it, because the USB live Ubuntu is not booting up and it hangs on the splash screen.

    Here's the logs

    I thought it might be because of my swap partition, because on any mode on in the recovery menu(from friend recovery) it hanged on fsck, so I just removed my swap partition and removed the /etc/fstab entry for the swap. Not sure it was the right way, but it didn't change anything.

    The USB works perfectly with a Dell Latitude E6500 laptop, even though I get the `not a typewriter message`.

    As I researched the 'cannot mount to /dev/sr0, no medium found' is also ok.

    Note that I don't want to remove all my partitions and make a clean install, that's gonna be my last resort.

    Any keyboard shortcut won't after that. Up and down arrows that shows the splash screen won't work after it's hung. `alt + ctrl + F1-7` won't do anything. Same goes to `alt + ctrl + delete`.

    One more thing is that having persistent storage or not having it, wouldn't make any difference. I made the usb with `dd` but, same results obtained with unetbootin or pendrivelinux.

    Your Dell Latitude E6500 laptop uses an Intel video chipset while your Dell Inspiron N4010 laptop uses an NVidia video chipset.

    The Intel GPU chipset has native support in xorg-xserver, while xorg-xserver usually needs to be told to use an NVidia driver or not to set KMS modes for higher end NVidia GPU chipsets.

    An easy test to see if this is going on in your instance may be to visit the Graphics Resoltution link in my sig line for instructions on how to add a nomodeset parameter during bootup of a LiveCD (USB), first half of Post #3...
