I agree, I was very happy with Ubuntu 10.10 but went to 11.04 thinking it would be great and was disappointed. Nice to hear Kubuntu isn't the same, maybe I'll load that one up today.
I had the same issue with two different laptops. Very disappointing.
The same thing happened to me. I ugraded to 11.04 and the machine would no longer boot. Tried a fresh install with no luck either.
I switch to Mint Linux after that. It seems pretty nice so far.....
