Comment 4 for bug 648165

I really do sympathize with your situation but in order to help you, you have to provide more info about your issue and hardware. If you looked at the page I referred to, https://wiki.ubuntu.com/X/Debugging, it would steer you in the right direction in terms of what is possibly going wrong with your computer and provide some workarounds. I am assuming that you are trying to use the Live CD on a computer that already has a version of Ubuntu installed on it. Even if you can not fully utilize the 10.04 and/or 10.10 Live CD to retrieve logs of usplash or Xorg crashing, you can provide more than just a description about your hardware and issues via your already working OS, 9.10.

https://wiki.ubuntu.com/X/Debugging lists several methods for retrieving debugging info such as entering the following commands in a terminal and attaching the files to this bug report.

lspci -vvnn > lspci-vvnn.txt

sudo dmidecode > dmidecode.txt

With these files we could view the hardware you are using and search other bug reports and/or ubuntuforums.org, to see if other people are experiencing similar issues.

In one way that 10.04 and 10.10 differ from previous versions of Ubuntu is that the kernel handles setting screen resolutions (kernel mode setting, KMS), while in previous versions screen resolutions were handled by X (xorg.conf). That is why there is no "Low Graphics Mode", with KMS, the kernel is attempting to set the highest possible resolution that both the monitor and video card are capable of displaying.

While using the Live CD, I would suggest pressing the F6 key at the menu screen (where you can choose to install or just try K/X/Ubuntu) select the "nomodeset" boot option and continue to install/boot.
