After a few hours of toil and despair of trying to tweak my Dell Mini with Ubuntu in an attempt to enable the ability to use the 2GB of RAM instead of being limited to just 1GB. At one point I had the 2GB recognized but lost wifi and sound. In the end I completely reinstalled the initial Dell Ubuntu 8.04+ OS, did a full apt-get update and install…. and everything worked (2GB of RAM, wifi, sound, and on board webcam). And by now in Ubuntu I can add my network printers and permanently mount my networked shared drives with my eyes closed.
And yes, the Dell Mini is just a bit more zippy with 2GB of RAM humming under the hood.
