[Q] Unresponsive touch screen

view story

http://forum.xda-developers.com – So I have a problem with my CUBE U30GT-H. I bought it almost 3 months ago, all have worked very well, but now touch screen doesn't. Problem occurs when I have to unlock screen, it simply doesn't work after sleep. But when I restart it works again, tablet totally works with my mice. I tried to wipe cache and reinstall firmware, but nothing changed. So i think it will be a good option if touch screen doesn't shut down when tablet put to sleep. I was searching for a touch screen config, but didn't find. I hope you can help me with problem and give some ideas. Now I use this firmware Evolution (HowTos)
