Comment 22 for bug 742544

I just stumbled across a very useful blog post which fixed my dual-monitor setup problems!

The short python script works like a charm for me and cloning/extending my laptop screen to a second monitor only takes me 1 click! The launcher appears on the right side as well, without enabling/disabling everything twice (as described in my post above).

AFAIK, disper (the display-switching utility) only works with Nvidia graphic cards at the moment...
