<pre>Hmmm so this could be Optimus related? In the BIOS, the Display has 3 separate
modes:
- Integrated (works, using Intel driver)
- Discrete (uses nouveau driver)
- Optimus
All my attempts so far to get this to work with nouveau have been using the
"Discrete" setting - I don't really care about switching between cards on the
fly, I'd just like to be able to use the external DisplayPort connector.</pre>
