Besides a number of other issues, I still cannot enable Compiz or any effects with Maverick on a Thinkpad X201. I understand this laptop is supported by Ubuntu, yet I have found a good number of posts reporting problems. I would like to know if they have been solved by now.

Here are further details on some of the failures after another clean install:

I feel your pain as the proud owner of a T510 with i915. I had way too many freezes to be productive, and this was 10.04. I ended up disabling compiz completely, and eventually installed Enlightenment which was much more stable and faster.
So how does this help you? I type this post on an Acer aspire one D255E which is using i915 on Natty and have not encountered a single graphics issue, all the eye candy works, it's responsive, no hangs, no nothing. Suspend/Resume is fine but there's minor graphics glitch with hibernate, I can live with that.
So give Natty a try, you might find that your graphics trouble have gone away. Barring that, you should be able to install the Natty kernel on Maverick via backports. That could help things. I don't know about a backports for Xorg, I presume that's alot of extra packaging work. Hope that helps.
