I tried installing Karmic onto a fresh partition of my hard drive the day it came out, and have had nothing but a huge head-ache ever since. I've tried everything I and Google can think of, and none of it has worked, so I'm hoping someone here can help me out.
Here's the problem. First, the Live CD would not start. After selecting "Try Ubuntu without changes to your computer" it proceeded to a black screen instead of the boot screen, and eventually made the startup noise but the screen never worked. After some Googling, I tried starting it with 'i915.modeset=0' and it worked! I installed Ubuntu to the fresh partition with ext4, and restarted with hope that my new system might work.
It didn't, but then I remembered the i915 workaround, and added 'i915.modeset=0' to the list of boot options. Here's the weird part: it seemed to start up, got to the login screen and... was unresponsive. It was like the keyboard and mouse were completely disconnected from the computer. This really confused me because the Live CD didn't have that glitch at all, and this was a fresh installation so it should behave much like it.
Anyway, I tried booting to recovery mode, which the keyboard did work in, and using 'X -probeonly' got some rather cryptic errors, which I would greatly appreciate some help in interpreting.
