Afrer installing new rom I no longer have the landscape on screen board any ideas on how to get it back
This thread contains one way to get it back:
AllDroid - View topic - [release]Launcher 2.0.1 w/ 5Screens v1.1a AuRot *Upd 1/6/10*
To be honest, unless you are pretty savy, this might be problematic.
The easiest way is to pick a rom with what you want. And, you and I are in the minority it seems. Most folks don't want autorotate. And most folks want wifi, so the rom developers tend to err on the side of no autorotate, and wifi. And if not careful, wifi can break other things. These can be patched, but it means more step for you.
