I am having difficulties, to get Ubuntu 11.10 to work. For the 11.10 version, if I click install, or if I click try Ubuntu, I only get a blank screen, that just stays there.

If I use "nomodeset", it changes to a loading screen and after about 2 minutes it goes back to black screen - however, before it goes black, i get a few errors, like:

bad target number, or passwd error mode (something like that). I've also tried (xforcevesa, i915.modeset=0, nomodeset, radeon.modeset=0, i915.modeset=1)

I have also tried the alternate installation, which installed fine, however when I boot up, select it from "grub", it goes black.

I did manage to install 10.04, however the screen resolution was 800x600 and I couldn't fix it to 16:9 (my resolution). I don't wanna use 10.04, because I would like the new one 11.10, and would like to use it.

Any help would be GREATLY appreciated. Thank you
