After complete installation, when you see in status bar the notification, you should click that notification... if not you will get this problem with the keyboard...try to reboot and if you see any notification acknowledge it, it will resolve this keyboard problem..
did you change the kernel?
are you using dual boot? if yes, it happen also to me, that is why i revert to single boot only...
But, I will check this, as this is not happen to me after I revert to single boot...
didn't change the kernel. also didn't get any notification in the status car either.
I wiped everything twice before I flashed as well. I would love to try this rom if I can get it to work.
