Re: Black Screen When Attempting Using the Lubuntu LiveCD
Don't know if it will solve the problem or not, but the I945 is one the gpu's that sometimes requires nomodeset. I *think* for that series of Intel it might be either "i915.modeset=0" or "i915.modeset=1" that you need to add to the boot line. You should be able to add that entry via an entry on the menu before selecting Try Ubuntu. There are MANY posts on the forum about using nomodeset (used to be for nVidia only, but it may be all-inclusive now) - follow one of those posts but replace "nomodeset" with one of the options I put in quotes above (don't include the quotes).
A duck is a duck is a duck, unless, of course, it's a horse or a table.
