Jeff Lane  (bladernr) wrote : [ThinkPad T510] Ext VGA/DisplayPort does not function

Natty testing on the ThinkPad T510. Neither the external VGA nor DisplayPort ports work when connected to an external monitor. I tried both waiting for the automatic config that should happen as well as using the hotkey to turn on the external monitors.

Nothing I tried was successful.
