The patch 7409 from upstream fixes the issue for my laptop, when using the latest git version. Now I ported the patch (the best I could) to the Edgy version, and it still works. Currently, the Edgy and Feisty versions are almost the same, so I expect this patch to work in Feisty as well.
However, upstream is not totally happy about their patch, as it is kind of a workaround and not fixing the real issue at its origin. ** Attachment added: "upstream patch 7409 modified for Edgy" http://librarian.launchpad.net/6456764/13_fdo_att7409_bug5473.diff -- [x700] fails to infer lvds for primary connector on acer ferrari 4005 | card detected, but driver fails to use right output port https://launchpad.net/bugs/22985 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
