A little (successful) experiment

Which actually made a whole mess (and produced a worst picture...)

The old and trusty Apple Cinema Display hooked to the Thinkpad T140 via DisplayPort... On Lucid Lynx... With NVIDIA's proprietary drivers.
The thing works marvelously.

Got the adapter dirt cheap during the holidays, and it is actually rather nice to know that it is possible to use that hugemongous external monitor on Linux with this laptop.
