I too am having problems with the digitiser.
I started with CM11 which worked for a little bit but I found these bugs:
a) If you leave the install so it goes into sleep then the digitiser doesn't work when you bring the phone back with the power button.
ii) After a while the digitiser stops working (maybe a half hour - could be related to deep sleeping?). A clean install (from the very beginning with TPT) brings it back. Power cycling is not enough.
I am now trying 10.2 to see if it works....
Well initially the tocuscreen was unresponsive but I got it working by pulling the battery after the first time round during the initial setup session language selection (no touch screen=no power off confirmation!) and the second time it seemed to come up to the first config screens a bit quicker and the digitiser then worked.
So I'll monitor this and report back if it survives or not.
I wonder if there are different hardware revisions out there that are behaving differently?
The IMEI of this one is 3554580403xxxxx and I have a job lot I bought off ebay for a fiver each so I'll try a few more out.
I had a couple more digitiser lock-outs but running CWM and rebooting via that seems to clear the condition - in case that helps to track it down.
