Didn´t happen to me, yet.

You could workaround it for the time being with disabling lockscreen and assigning wake up to the volume keys, no idea though if that option is in the rom. it is in cyanogen, so even if not there should be an app for that

 

Or it´s a problem with the rom installation, maybe you should consider giving the 1.05 or the 4.2.2 beta a go...

Thanks Mate,

I had tried:-

1) Upgraded to 4.2.2 and downgraded to 4.1.1 several times but nothing has been improved. Still unable to sleep/wake up with any buttons.

2) Edited Keypad.kl and assigned WAKE_DROPPED on volume buttons and reboot but which also not working too.

There is still no way to wake the screen up and turn to back on, I am still reboot the system when the device are into sleep moed......
