Dual-LVDS Acer Iconia laptop

Hi Guys,

I've seen on the list that some of you (as we were) have troubles with
the second screen on the iconia laptop.

In our lab, we managed to make it work by using two patches:
* http://web.archiveorange.com/archive/v/rNRcWX4nB2U5uRmbLm9h (LVDS are
digital as well), this solved the "xrandr disconnected" issue
* a small patch we are finalizing to call the right DMI function to
light up the second LCD.

So, as soon as we have clean this code, this bug will be solved.

Cheers,
Benjamin

PS: I'm sorry to start a new thread as I just registered myself on the
list and was not able to get the previous Message-ID.

Awesome, thank you! It's quite frustrating to see that this patch was written
almost 6 months ago then forgotten...

It's already compiling, let's see if it works :)

This first patch seems indeed based on an old tree, it requires some
small changes to apply.

No problem, I'll post on the original thread for the record.

Thank you again,
