From cede2cb6ee9b0ddaa3dbc9939418ff177a831600 Mon Sep 17 00:00:00 2001 From: Pekka Enberg Date: Tue, 16 Jun 2009 19:28:45 +0000 Subject: [PATCH] eeepc-laptop: enable camera by default If we leave the camera disabled by default, userspace programs (e.g. Skype, Cheese) leave the user out in the cold saying that the machine "has no camera."
