I have a Lenovo X1 i5vPro 2.50Gh x 4, which works fine with 12.04 LTS 64.... except the right click on the touch-pad, which I can live with.. However, I have just bought a Genuine Lenovo 39+ slice to extend usage.
If I boot with the slice attached I have two strange events:
- The battery shows as one battery so I can't tell the state of the internal batteries from the slice.
- If I then suspend by closing the lid when I open it again the screen is black with just the mouse pointer. I have tried just typing my password but it just sits there and does nothing.
If I boot with no slice attached all is well and works fine. If I then attach the slice the slice is detected and shows as another battery so can see the state of both. However, the time left is shown in % of charge and not time left before flat.
The other strange thing is that with the two batteries showing if I check the Power statistics they are shown as separate batteries with their own statistics. However, if booted with the slice on and showing only one battery attached the Power Statistics falters and show nothing despite the batteries both being there ans showing as 100% next to the Icon next to the BlueTooth icon.

For your problem with black screens when resuming, I suggest you keep an eye on this bug. It's currently affecting me on my ThinkPad X200, and I'm using GNOME Shell as a workaround while the bug is being fixed.

Since X1 Carbon hasn't gone retail yet, I'd be surprised if you get a lot of feedback on this issue. However, from the "i5vPro 2.50Gh x 4" description I figure you have the regular X1 (with glossy gorilla display) which should be "Ubuntu Certified" according to this.
From what I can gather from the internet (sorry no personal experience, hopefully with the X1C though!) no one else seems to experience the same problem. Have you tried the recommended 32-bit install? Or even an dist-upgrade?
