I have MacBook Pro 13" (early 2011) hooked up to an external display. With Snow Leopard this setu worked fine. But after upgrading to Lion the external screen constantly blacks out. I've seen some suggestions saying that it might be the adapter but, as I said, this setup worked fine in Snow Leopard so I find it unlikely to be an adapter issue.

Does anyone have any suggestions on how to fix this problem? It's extremely annoying.
